Explanatory memorandum

1. SETTING UP THE GALILEO JOINT UNDERTAKING

The Galileo satellite navigation programme is the first major
programme to bring the European Union and the European
Space Agency together. It aims to develop cutting-edge tech-
nology to enable a user equipped with a receiver to receive
signals from several satellites and thus determine his exact
position in time and space anywhere at any given moment.
Galileo is based on a constellation of 30 satellites placed in a
approximately
medium earth orbit

earth. The final component

lation setting up the Galileo Joint Undertaking was formally

Thereafter,
associated with the growing satellite navigation service
markets in many areas,
the programme will be managed
during the deployment phase (2006-2007) and the commercial
operation phase (after 2008) by a private entity. The Galileo
Joint Undertaking will therefore issue a call for tenders in order
to select the private consortium which will be awarded the
concession for the deployment and operation of the system.

Four months after the historic decision of 26 March 2002, it
seems appropriate to review the state of progress of the Galileo
programme. The following five aspects will be discussed in
turn:

— establishment of the Joint Undertaking,

There have been delays in setting up the Galileo Joint Under-
taking following problems within the European Space Agency
in finalising the respective contributions of the participating
States contained in the programme declaration relating to
Galileo. Some Member States
are, mainly for political
reasons, claiming the status of the foremost contributor to
the programme, difficult
situation to deal with in the
framework of the European Space Agency Convention. If no
solution is found in the short term, the matter will have to be
referred to the European Union. The Joint Undertaking must be
set up as quickly as possible so that the plan for the call for
tenders for the development phase can be approved.

When these problems have been overcome, the first meeting
of the Administrative Board of the Joint Undertaking can be
held, preceded by the meeting of the Supervisory Board in
accordance with Article 3 of the Regulation. The Commission's
representative on the Administrative Board of the Joint Under-
taking has been appointed (2). According to the statutes, the

invitation to tender to the Council to enable the latter to
have all the facts when deciding upon the concession holder.
It will be a very important decision as it will also determine the

of the concession holder will be the financial contribution they
can make to the programme, which will determine the

private sector.

2. SYSTEM SECURITY

Article 7 of Regulation (EC) No 876/2002 stipulates that a
Security Board shall be established in order to deal with
security matters regarding the Galileo system.

The Council did not set up this body at present. In the interests
of efficiency, and in order to begin work on the fundamental
questions at the earliest possible opportunity, the Commission
has wasted no time in convening an initial meeting with the
security experts of

committee meeting chaired by the Commission on 8 May
2002, which was followed by other meetings on 25 June
and 13 September 2002.

At the meetings, some Member States expressed the wish for
these meetings to be chaired by a Member State representative,
and even co-chaired by a Member State and the Commission,
with the Commission fulfilling the role of Secretary. The
Commission is of the opinion that, until the Security Board
is in place, these expert meetings should continue operating in
its present form.

The Commission considers that the missions of the Galileo
Security Board are as follows:

3. DEFINING SERVICES AND THE FREQUENCY PLAN

3.1. Definition of services

Work has been carried out for several years on defining the
services and the frequency plan. The first version of
the
technical document defining Galileo's mission and, hence,
also the range of associated services, was produced at the
beginning of 2001.
It has been widely distributed and
discussed, by both user groups and Member States, particularly
at a meeting of the Member State representatives held in the
European Space Agency in March 2001. The second version of
the document, widely circulated in April 2001, was the result
of this consultation.

Following the Council Decision of 26 March 2002, and devel-
opments in the technological concepts resulting from work
carried out during the definition phase, a new version was
produced (see summary in Annex 1)
taking into account
fresh consultations of large user groups for whom a number
of forums were specifically organised in May and June 2002.
The consolidated version of the technical document has just
been forwarded to the Member States. It should help define:

— the list of services which Galileo should offer,

— service performance (quality),

— technical characteristics of services.

If the programme is to run smoothly, it is essential to make
final decisions on these aspects by the end of 2002 since they

(satellite design, ground station architecture,
frequency plan,
etc.) which must be identified before issuing the invitation to
tender for the whole of the development phase (2002-2005).
Making substantial amendments to these specifications would
significantly increase the costs of this phase of the programme.

C 248/4

In addition, the services must be defined before progress can be
made in international negotiations, particularly with regard to
aspects of interoperability with the American GPS and Russian
Glonass systems, and in order to define the specification for the
the Galileo system. The industrial and
future operator of
financial groups interested in tendering for
the operating
concession must have the information in order to draw up
their bid and their business plan. Lastly, European equipment
manufacturers have to start designing their products as of
today. Failing to define and make known the services will
compromise the design of the receivers (with the sale and
provision of associated services accounting for 85 % of the
market created by Galileo) and the development of
the
satellite navigation applications market.

Galileo will offer several service levels, from open access to
restricted access of various levels:

— an open, free basic service, mainly involving applications
for the general public and services of general interest. This
services is comparable to that provided by civil GPS, which
is free of cost for these applications, but with improved
quality and reliability,

— a commercial service facilitating the development of

The guarantees regarding the specific basic parameters of the
services provided (precision, availability, etc.) will be of benefit
not only to the insurance sector (tracking stolen vehicles,
premiums adjusted to the actual movements of the vehicles,
monitoring movements of goods, etc.), but also in high-tech
sectors such as oil prospecting, precision crop management,
freight management, etc.

The provision of an integrity message to determine the relia-
bility of the satellite signal is also essential in the many sectors
where a legal guarantee is required (service industries) and in
cases where human life is at risk. For example, in some phases
of flight, civil aviation demands that there be a delay of no
more than six seconds between the detection of abnormal
operation and the user's receiving an appropriate warning
signal.

The existence of a very low speed communication channel (in
the order of 500 bits per second) can also be used to transmit
commercial
information from service centres to users. The
detailed content of such information (distribution of encryption
decoding keys, traffic information, routing of different users,
etc.) may be determined by the future operator according to
their business plan.

local
All services are directly accessible worldwide. However,
bodies may have to make some adaptations
to specific
environments or user communities (tunnels, airports, ports,
etc.). In addition, the satellite infrastructure can be comple-
mented by regional components, particularly for producing
the integrity message.

It is worth emphasising that the services offered by Galileo will
cover the whole planet, particularly areas at a geographical
disadvantage and the outermost

The real needs of future Galileo users need to be identified
before the characteristics of the package of services can be
decided. Studies have already been carried out in various stan-
dardisation institutes and international bodies, such as the
International Civil Aviation Organisation,
the International
Maritime Organisation, etc.

The range of Galileo services is designed to meet practical
objectives and expectations, from improving the coverage of
open-access services in urban environments (to cover 95 % of

3.2. The need for a public regulated service (PRS)

Satellite navigation enables a user to determine his position in
time and space to an unprecedented degree of precision at very
little cost, thus explaining why it is widely used in all sorts of
areas. However, open signals are extremely sensitive to inter-
ference or to deliberate — potentially hostile — manipulation.
The need for a PRS service is conditioned by the vulnerability
of satellite navigation signals, the special features of the service
and the very sensitive nature of the anticipated applications.

3.3. The problem of the overlay of signals

A number of signals and frequency bands are associated with
the various services offered.

the overlay of

Considering the limited space in the frequency spectrum
allocated to satellite navigation,
frequency
bands used by GPS and Galileo is inevitable, particularly for
secured signals. Such overlay complies with international regu-
lations provided that there is no harmful interference to either
of the two systems. However, the United States, who until now
enjoyed a de facto monopoly of satellite radionavigation, are
currently — for strategic reasons — opposed to overlay of one
of the two PRS signals and one of the two military (or code M)
GPS signals at a specific modulation in the high frequency
band.

The selection of frequencies for Galileo's PRS signal is perfectly
justifiable in technical terms, however, as this is the frequency
spectrum which offers the best performance in peacetime,
particularly in terms of resistance and robustness, the best
cost/benefit ratio, and the best guarantee of continuity and
integrity. These qualities are equally valuable in a crisis. The
arguments put forward by the European Community are as
follows:

— it has the know-how to operate a secured signal,

— it believes that the complementary operation of the GPS
and Galileo systems must depend on mutual trust, and

spectrum needed for the transmission of the corresponding
signals. The World Radiocommunication Conference (WRC),
under the aegis of the UN, is the international forum where
over 150 countries negotiate the allocation of the frequencies
available within a physically limited spectrum to different
services. It is vital that the next WRC in June and July 2003
confirms the frequency plan already allocated to Galileo, as
well as its characteristics. This conference will be prepared
pursuant to the provisions of the Radio Spectrum Decision
of the Council (1).

4.1. Rights gained at WRC-2000 in Istanbul

At
the Istanbul World Radiocommunication Conference, a
further frequency spectrum was allocated to satellite radionavi-
gation services. No frequency spectrum was, however, allocated
specifically to Galileo or to other radionavigation systems.

International Telecommunication Union (ITU)

Following the Istanbul WRC, a number of countries applied to

the
allocated frequencies for different satellite navigation systems,
particularly Galileo. Given the limited frequency spectrum
available, the next WRC in 2003 must validate the coexistence
of different systems within that spectrum. What is more, a
large part of the frequency spectrum allocated to satellite radio-
navigation is already reserved as a priority to aeronautic radio-
navigation services (ARNS) (2). All new satellite navigation
systems,
including Galileo, must therefore demonstrate that
they do not cause interference with these priority services.

— it has a prior claim on the right to use the signals.

4.2. Objectives for the next WRC

Accordingly, the total overlay of one of the two PRS signals on
one of the M code signals is not only possible but desirable,
especially as:

— overlay is authorised by international regulations,

— the possible alternatives are less efficient and have not been

technically validated.

In order to settle this difference of opinion with the United
States, the Commission has in particular proposed an exchange
information to the American authorities. It has

Committee was a trustful interlocutor to discuss matters with

4. RESERVATION OF FREQUENCIES

The definition of services and the frequency plan presented
below presuppose that Galileo has access to the frequency

At WRC-2003 there will no longer be the need to seek access
to the frequency spectrum for Galileo, unlike the situation at
WRC-2000. What we must do, however,
is ensure that the
frequency spectrum allocated to satellite navigation affords
the flexibility needed for Galileo to provide all the planned
services. We must therefore ensure that the WRC ratifies the
technical characteristics of the frequency spectrum to be used
for Galileo services and their compatibility with other systems
in terms of the acceptable level of interference.

The outcome of WRC-2003 will be crucial to the coordination
of the various satellite radionavigation systems (Galileo, GPS,
Glonass, the Chinese systems) within the allocated frequency
spectrum.

We must therefore prevent countries such as the United States
or the Russian Federation or organisations such as the Inter-
national Civil Aviation Organisation (ICAO) imposing excessive
restrictions on the frequency spectrum already allocated to
Galileo.

4.3. The strategy to be adopted to defend Galileo's

interests at WRC-2003

Preparations for WRC-2003 should focus on the following four
priorities:

— final definition of the services and the frequency plan (see
section 3 below) in order to complete the technical spec-
ifications for Galileo,

— ensuring consistency between the various EU policies on

frequencies and between the various EU players,

— maintaining close relations with the main non-EU players
involved in preparing WRC-2003 (CEPT, ITU, Eurocontrol,
ICAO, etc.),

— enlisting the widest possible support for Galileo from third
countries and world regions at the WRC. The necessary
action should be taken on these priorities.

know-how and reduce the technological and political risks of
the programme. As well as assisting technical standardisation
with existing systems, cooperation is essential for penetrating
markets and developing ground-based equipment. It therefore
also falls into line with the European Union's objectives in
terms of foreign policy, development cooperation, employment
and the environment.

Since the Council Decision to launch the Galileo programme, a
number of third countries have expressed a wish to be involved
in the programme in some way. Moreover, the Commission
regards the Galileo programme as being of world importance
and, as such, of interest to all third countries.

terms, cooperation with third countries means

In this context, consideration must be given to the differences
in the application of export controls noted between the

international systems, particularly with regard to arrangements
for monitoring intangible technology transfer, the extraterri-
torial aspects of some legislation, re-exporting conditions, etc.

(a) United States

The principal partner

displayed renewed interest in signing an agreement with
the European Community. A successful initial negotiation
meeting was held in Brussels on 21 and 22 June 2002. The
next meeting is planned for October. The aim is to reach a
cooperation agreement with the United States by the end of
2003, outlining the principles of
interoperability and

Galileo and GPS.

is covered by the multilateral

It should however be examined whether some loopholes
(goods or services) would require introducing a special
clause in the future bilateral agreement presently under
negotiation.

A great step forward was also achieved in terms of inter-
the
operability. The United States were notified that
European Community would be using its own standards,
often identical to the international standards, rather than
the GPS system standards, a choice dictated by the quality
of the services to be offered to users (signal continuity and
reliability, precision, low cost of receivers, etc.). Galileo is
also a commercial project, after all, and GPS is not the
international standard. Galileo will be a constellation that,
while complementary to GPS and interoperable for GPS
users, will be quite independent of the GPS system.

The European Community also presented the project's state
of progress and illustrated the suitability of the technical
solutions adopted (time, geodetic, frequency planning) in
terms of quality of service and interoperability with GPS
for the user. The best experts from the Member States were
brought in to participate in the meeting. They presented a
united front. The European and American experts will meet
before the next negotiations in October. Technical work on
the specific questions at issue should make it possible to
overcome the final obstacles to defining the principles
governing Galileo/GPS interoperability.

It has not, however, been possible to make progress on the
thorny issue of the overlay of one of the frequency bands
intended for Galileo's future public regulated service on one
of the future American military (code M) signals. The US
negotiators are not authorised to tackle this matter, given
its high political sensitivity. The United States regards
NATO as the only forum in which the matter may be
discussed.

The Europe Community's political decision to equip itself
with its own satellite navigation system is based on the
supposition that it should retain genuine control of the
secured PRS signal
to
accepting a situation of relative independence in which
the use of the ‘government’ signal would be subject to
certain conditions.

in its negotiations with the Americans,

Until now,
the
Commission has put forward the scenario that the United
States will not be able to jam one of the planned PRS
signals because it will be overlaid on one of the future
military GPS signals and it is not possible to selectively
jam one of
two signals overlaid on a single frequency
band with the same modulation. As explained in point
3.3 above,
the modulation used for the overlay would
enable Galileo to transmit a much more ‘robust’ and
reliable signal. As a result, the United States would not
be able to selectively jam Galileo PRS users. A political
agreement on the cooperation necessary between the two
radionavigation systems is required in preparation for a
crisis or in the event of a crisis.

Contacts with Russia and China regarding Galileo cover
many areas of cooperation. Both countries have advanced
satellite radionavigation programmes and view cooperation
with the European Community as a strategic objective. One
major issue is the relationship between Glonass and Galileo
systems and standards. In tandem with its expressed wish to
participate in the Galileo programme, China is
inde-
pendently developing a regional system adapted to its
own needs and has applied to the International Telecom-
munication Union for access to frequencies dedicated to
satellite navigation.

As well as promoting industrial and scientific links, it has
been agreed that negotiations will be resumed with a view

People's Republic of China: The demographic, economic
and political role of China and its satellite radionavigation
activities warrant the country a special place in the Galileo
programme. Following the Sino-European summit held in
June 2001, cooperation with China took the form of visits
by experts and two major conferences bringing together all
the Chinese scientific, technical and commercial operators.
The last such conference, held in Beijing on 3 and 4 June
2002, was organised with the help of the European Space
Agency.

When Vice-President de Palacio met Minister Xu Guanhua
on 17 June 2002, an announcement was made regarding
the future establishment in China of a Sino-European centre
for cooperation on satellite radionavigation. It is intended
to set up teams of European and Chinese researchers
working on Galileo and on radionavigation in general
with a view to promoting industrial partnerships
to
research and exploit the applications of this technology.

The Chinese Prime Minister, Zhu Rongji, expressed his
in being fully involved in the Galileo
country's interest
programme financially,
technically and politically. The
Chinese Ministry for Research presented a list of areas of
cooperation which could be covered by formal agreements
between the European Community and China.

Considering both the state of progress of potential coop-
eration with China, the importance of the stakes of colla-
boration with this country in terms of markets, policies on
standardisation and frequencies, and the political objectives
of both parties in terms of sovereignty, technology transfer,
etc., the Commission will shortly present a proposal for a
directive on specific negotiations with China.

The Mediterranean region has expressed great interest in
Galileo and in its precursor, Egnos. Because of
their
geographic and economic proximity, the countries of the

‘cooperating State’. The matter is currently under discussion
in Ottawa. In technical terms, Canada is still taking part in

5.2. Participation of third country members in the Joint

Undertaking

On the subject of the possible forms of cooperation with third
countries, it should be noted that Article 5 of the Regulation
setting up the Galileo Joint Undertaking specifically provides
for third country members to take part in the joint under-
taking.

In addition to the negotiating directives issued by the Council
which, by definition, cover a wide range of subjects (scientific
and industrial cooperation, commercial matters, etc.), there is
the specific issue of third country participation in the activities
of the joint undertaking.

India: The Indian aviation and research authorities are
trying to set up a first-generation (Egnos or WAAS type)
satellite radionavigation system. European and American
industries are in competition over
this. The aviation
sector is of critical
importance in this project because of
the imperatives of air safety, with Indian airspace crossed
by a considerable number of international flights.

At present, a number of countries have expressed interest in
becoming involved in the Galileo programme in this way. This
means, however, that the countries concerned and the Joint
Undertaking will have to have discussions in order to work
out appropriate arrangements.

cooperation with India to allow it
to use Galileo's
precursor, the Egnos system. The aim is to ensure that
European technology forms the basis of any future navi-
gation system developed by India, which claims to own its
own radionavigation system.

The founding members of the Joint Undertaking, applying their
own decision-making procedures, will have to assess the terms
of this participation, including, in particular, the amount of the
financial contribution to the joint undertaking, the approval —
by the country concerned — of the key elements of Galileo
strategy (1), protection of Galileo infrastructure, acceptance of
the EU principles regarding the transfer of technology and
intellectual property.

The Council still has to approve their participation, on the
basis of Commission proposals, and any conditions attached.

ANNEX 1

GALILEO MISSION AND SERVICE DEFINITION

General introduction

The main characteristics of the Galileo programme and the services and performances offered are presented in the
high-level definition document. It is used as the framework for the Galileo programme and is applicable to the mission
requirement document. The document prepared by the European Commission and the European Space Agency results
from a consultation process with users, Member States and prospective investors and takes into account the latest results
of technical definition studies performed so far.

The European objective of full autonomy in satellite navigation will be achieved in a two-step approach, starting with
the EGNOS system in 2004 and then with the Galileo system, which is aimed at full operational capability by 2008.
Galileo will be the first civil satellite positioning and navigation system, designed and operated under civil control.
Galileo will be interoperable with other systems to facilitate their combined use. For safety of life and commercial
applications, the navigation services will offer a guarantee, which is not only advantageous, but also an important
differentiation with respect to the current GNSS. Special attention has been given to security aspect of Galileo, to protect
its infrastructure and to avoid the potential misuse of its signals.

Four navigation services and one service to support search and rescue operations have been identified to cover the
widest range of users needs, including professional users, scientists, mass-market users, safety of life and public regulated
domains. The following Galileo satellite-only services will be provided worldwide and independently from other systems
by combining the Galileo's signals in space:

(i) The Open Service (OS) results from a combination of open signals, free of user charge, provides position and timing

performances competitive with other GNSS systems.

C 248/12

EN

Official Journal of the European Communities

15.10.2002

(ii) The Safety of Life Service (SoL) improves the open service performances providing timely warnings to the user when it
fails to meet certain margins of accuracy (integrity). It is envisaged that a service guarantee will be provided for this
service.

(iii) The Commercial Service (CS) provides access to two additional signals, to allow for a higher data rate throughput and
to enable users to improve accuracy. It is envisaged that a service guarantee will be provided for this service. This
service also provides a limited broadcasting capacity for messages from service centres to users (in the order of 500
bits per second).

(iv) The Public Regulated Service (PRS) provides position and timing to specific users requiring a high continuity of service,
with controlled access. Two PRS navigation signals with encrypted ranging codes and data will be available.

(v) The Search and Rescue Service (SAR) broadcast globally the alert messages received from distress emitting beacons. It

will contribute to enhance the performances of the international Cospas-Sarsat search and rescue system.

The Galileo satellite-only services can be enhanced on a local basis through combination with local elements for
applications with more demanding requirements.

Galileo signals can also be combined with other GNSS system (Glonass, GPS) or non-GNSS systems (e.g. GSM and
UMTS) to allow enhanced services for specific applications.

A service-oriented approach has been used to design the Galileo architecture. The Galileo global component, comprising
the constellation of 27 active satellites + three spare satellites in medium earth orbit and its associated ground segment,
will broadcast the signal in space required to achieve the satellite-only services. The local service enhancements will be
facilitated, as the global component will be designed to easily interface with local elements. In the same way, the
interoperability between Galileo and external components will be a major driver of the Galileo design to allow the
development of applications combining Galileo services and external systems services (e.g. navigation or communication
systems).

OPEN SERVICE

Purpose

The Galileo Open Service provides positioning, velocity and timing information that can be accessed free of direct
charge. This service is suitable for mass-market applications, such as in-car navigation and hybridisation with mobile
telephones. The timing service is synchronised with UTC when used with receivers in fixed locations. This timing service
can be used for applications such as network synchronisation or scientific applications.

Performance and features

The performance objectives in terms of position accuracy and availability will be competitive with respect to existing
GNSS and further planned evolutions. In addition, the Open Service will also be interoperable with other GNSS, in order
to facilitate the provision of combined services.

Implementation

The Open Service signals are separated in frequency to permit the correction of errors induced by ionospheric effects by
differentiation of the ranging measurements made at each frequency. Each navigation frequency will include two ranging
code signals (in-phase and quadrature). Data are added to one of the ranging codes while the other ‘pilot’ ranging code is
data-less for more precise and robust navigation measurements.

COMMERCIAL SERVICE

Purpose

The Commercial Service will allow the development of professional applications, with increased navigation
performances and added value data, compared with the Open Service. The foreseen applications will be based on:

— dissemination of data with a rate of 500 bps, for added value services,

15.10.2002

EN

Official Journal of the European Communities

C 248/13

— broadcasting of

two signals, separated in frequency from the Open Services signals to facilitate advanced
applications such as integration of Galileo positioning applications with wireless communications networks, high
accuracy positioning and indoor navigation.

Performances and features

The Galileo Operating Company (GOC) will determine the level of performance it can offer for each commercial service
together with ascertaining the demands of industry and the needs of the consumer. It is intended to provide a guarantee
for this service.

The Commercial Service will be a controlled access service operated by commercial service providers acting after a
licence agreement between them and the GOC.

Commercial service providers will make decisions on the offered services: e.g. integrity data, differential corrections for
local areas, etc., which will depend on the final characteristics of the other services offered by Galileo.

Implementation

The Commercial Service signals will be the Open Services signals, plus two encrypted signals (ranging codes and data),
on the E6 band.

SAFETY OF LIFE SERVICE

Purpose

The target markets of the Safety of Life Service are safety critical users, for example, maritime, aviation and trains, whose
applications or operations require stringent performance levels.

This service will provide high-level performance globally to satisfy the user community needs and to increase safety
especially in areas where services provided by traditional ground infrastructure are not available. A worldwide seamless
service will
increase the efficiency of companies operating on a global basis, e.g. airlines, transoceanic maritime
companies.

Performance and features

With regard to Safety of Life Services, there are certain levels of service that are stipulated by law in various inter-
national transportation fields, for example, standards and recommended practices (SARPS) by ICAO. A very specific level
of service from Galileo will be needed to comply with legislation applicable for all considered domains of transport and
existing standards. It is intended to provide a guarantee for this service.

This service will be offered openly and the system will have the capability to authenticate the signal (e.g. by a digital
signature) to assure the users that the received signal is the actual Galileo signal. This system feature, which will be
activated if required by users, must be transparent and non-discriminatory to users and shall not introduce any
degradation in performance.

The provision of integrity (1) information at global level is the main characteristic of this service. Non-European regions
could also support the provision of this service on a regional basis by delivering regional integrity information through
the Galileo satellites.

The Safety of Life Service will be provided globally. Its specification include two levels to cover two conditions of risk
exposure and are applicable to many applications in different transport domains, for example air, land, maritime, rail:

— the critical

level covers time critical operations for example,

in the aviation domain approach operations with

vertical guidance,

— the non-critical level covers extended operations that are less time critical, such as open sea navigation in the

maritime domain.

(1) Integrity is the ability of a system to provide timely warnings to the user when it fails to meet certain margins of accuracy.

C 248/14

EN

Official Journal of the European Communities

15.10.2002

The SoL Service signals are in the E5a + E5b and L1 bands. Galileo will offer a robust service to the Safety of Life
community providing also alternative levels of service for degraded modes of operation (e.g. where one or two
frequency would not be available due to interference).

Implementation

The Safety of Life Service signals are separated in frequency to permit correction of errors induced by ionospheric effects
by differentiation of the ranging measurements made at each frequency. Each navigation frequency will include two
ranging code signals (in-phase and quadrature). Data are added to one of the ranging codes while the other ‘pilot’
ranging code is data-less for more precise and robust navigation measurements. The integrity data will be broadcast in
the L1 and E5b bands.

PUBLIC REGULATED SERVICE

Purpose

The Public Regulated Service (PRS) will provide a higher level of protection against the threats to Galileo signals in space
than is available for the open services (OS, CS and SoL) through the use of appropriate interference mitigation tech-
nologies.

The need for the PRS results from the analysis of threats to the Galileo system and the identification of infrastructure
applications where disruption to the signal in space by economic terrorists, malcontents, subversives or hostile agencies
could result in damaging reductions in national security,
law enforcement, safety or economic activity within a
significant geographic area.

The objective of the PRS is to improve the probability of continuous availability of the signal in space, in the presence
of interfering threats, to those users with such a need. Applications include the following:

(a) Europe-wide:

— the European Police Office (Europol),

— the European Anti-fraud Office (OLAF),

— civil protection services, safety services (Maritime Safety Agency), and those emergency response services

(peacekeeping forces, humanitarian response teams);

(b) in the Member States:

— law enforcement and security services,

— forces or services engaged in fighting crime,

— intelligence services responsible for national security,

— services responsible for controlling and supervising external borders.

The introduction of interference mitigation technologies carries with it a responsibility to ensure that access to these
technologies is adequately controlled to prevent misuse of the technologies against the interests of Member States.
Access to the PRS will be controlled through key management systems approved by Member States' governments.

Performance and features

The Public Regulated Service access will be controlled by the authorities to be defined at European level, through the
encryption of the signals and the appropriate key distribution.

15.10.2002

EN

Official Journal of the European Communities

C 248/15

Implementation

The Public Regulated Service signals are permanently broadcast on separate frequencies with respect to open Galileo
satellite-only services, so as not to lose the PRS when the open service is denied locally. They are wide band signals so as
to be resistant to involuntary interference or malicious jamming and therefore offer a better continuity of service.

The use of PRS will be restricted to clearly identified categories of users authorised by EU and participating states.
Member States will authorise users through the implementation of appropriate controlled access techniques. Control of
distribution of receivers will be maintained by Member States.

SEARCH AND RESCUE SERVICE

Purpose

The Galileo support to the Search and Rescue service — herein called SAR/Galileo — represents the contribution of
Europe to the international Cospas-Sarsat cooperative effort on humanitarian search and rescue activities. SAR/Galileo
shall:

— fulfil the requirements and regulations of the International Maritime Organisation — via the detection of emergency
position indicating radio beacons of the Global Maritime Distress Security Service and of the International Civil
Aviation Organisation via the detection of emergency location terminals,

— be backward compatible with the Cospas-Sarsat system to efficiently contribute to this international search and

rescue effort.

Performances and features

SAR/Galileo will allow for important improvements of the existing Cospas-Sarsat system:

— near real-time reception of distress messages transmitted from anywhere on earth (the average waiting time is

currently one hour),

— precise location of alerts,

— multiple satellite detection to avoid terrain blockage in severe conditions,

— increased availability of the space segment (27 medium earth orbit satellites on top of the four low earth orbit

satellites and the three geostationary satellites in the current system).

In addition, SAR/Galileo will introduce a new SAR function namely, the return link from the SAR operator to the
distress emitting beacon, thereby facilitating the rescue operations and helping to identify and reject the false alerts.

Implementation

The search and rescue transponder on Galileo satellites detects the distress alert from any Cospas-Sarsat beacon emitting
an alert in the 406-406,1 MHz band, and broadcasts this information to dedicated ground stations in the ‘L6’ band.
Cospas-Sarsat Mission Control Centres (MCC) carry out the position determination of the distress alert emitting beacons,
once they have been detected by the dedicated ground segment.

Galileo signals — main characteristics

The following chart describes the Galileo navigation signal emissions:

— four signals are transmitted in the frequency range 1 164-1 215 MHz (E5a-E5b),

— three signals are transmitted in the frequency range 1 260-1 300 MHz (E6),

— three signals are transmitted in the frequency range 1 559-1 591 MHz (L1).

Both the ranging code and data carry the specific information needed for a specific service. Among the 10 navigation
signals:

— six are designed for OS and SoL (signals 1, 2, 3, 4, 9, 10),

— two are designed specifically for CS (signals 6, 7),

— two are designed specifically for PRS (signals 5, 8).

ANNEX 2

ISSUES RELATING TO GALILEO SIGNALS

Introduction

The European Commission, European Space Agency (ESA), certain Member States (1) and the business world, notably
firms active in receiver design, have taken part in the work of the ‘Signal Task Force’ attached to the Galileo Steering
Committee. This Task Force began work in March 2001. One of its missions was to help define the signals to be
transmitted by Galileo. In this context, the best possible scenario in terms of the frequency and type of signals used was
devised to ensure that signals transmitted by Galileo would deliver optimum performance and thereby enable it to
penetrate the satellite navigation market. The experts appointed by the Member States reached a consensus on this
scenario.

Galileo will offer a range of services each using at least two frequency bands. Two of these services use unencrypted
signals. Two others rely on encrypted signals, one for commercial purposes and the other for critical and sensitive
applications under government control. This ‘governmental’ or Public Regulated Service has a high level of protection.

The American GPS system has two types of signals: civilian and military. The current GPS military signals are called P(Y)
and the future military ones are called code M.

The Signal Task Force has allowed for interoperability between GPS and Galileo. It works by overlaying the Galileo open
signals with two of the GPS frequencies, which will enable future open-signal satellite radionavigation receivers to use
GPS and Galileo signals together. It also allows for partial or total overlay of one of the encrypted PRS signals with one
of the forthcoming GPS code M signals. These overlays are possible from the technical and legal points of view.

For the moment the United States is opposed to the overlay of one of the Galileo PRS signals with one of the GPS code
M signals. It cites its defence policy priorities as its reason for wishing to retain the possibility of jamming the Galileo
PRS signal.

The analysis below first explains the issues raised by the United States and then goes on to set out the EU's position
regarding the choice of the Galileo PRS frequencies.

I. OVERLAYING THE PRS AND CODE M SIGNALS

1. The Galileo PRS signal

Of the various navigation services to be provided by Galileo, the PRS service is designed to ensure continuity of
service for certain sensitive applications (security, police, customs, fraud prevention), even in an emergency.

To ensure continuity of service and to prevent access to unauthorised users, the PRS signals are continuously
encrypted by a cipher or a government code and supervised by an appropriate European body.

PRS receivers will therefore be specific and very strictly controlled: users are identified by name, receivers are
traceable, stolen receivers are reported and disabled in accordance with a special procedure.

The PRS is composed of two signals: one in the medium-frequency band known as E6, the other in the high-
frequency band known as L1. The signal located in the E6 band is defined without any overlay with GPS signals as it
has sufficient bandwidth. The GPS code M also uses the L1 band, however.

2. Worldwide regulations (ITU)

According to current international regulations laid down by the International Telecommunications Union (ITU), the
frequencies that can be used by satellite navigation systems do not belong to any particular country or system. If a
countries wishes to use a frequency band it must file an application with the ITU. The first country to file an
application for a frequency has a priority claim on its use. However, any country may use the same frequency for its
own navigation system provided that it does not cause excessive electromagnetic interference affecting other systems
in use, including those having a prior claim.

3. Overlaying PRS and M code signals

The GPS code M and Galileo PRS signals each use different frequency bands. At the World Radiocommunication
Conference (WRC) held in Istanbul in 2000, it did not prove possible to obtain sufficient bandwidth in the L1 band
for all the potential signals. The GPS M code therefore overlaps with the Galileo PRS signal.

Two years of studies on interference by the best European experts have led to the firm conclusion that the European
Union is capable of designing a PRS navigation service that will not interfere with the GPS M code, including in the
high L1 band.

Therefore, international regulations allow the Europe Community to use for its own Galileo system the frequencies
on which GPS operates, including the GPS military signals and in particular M code, provided that Galileo does not
cause interference harmful to the American system. There is no technical or legal obstacle standing in the way of
overlaying one of the two Galileo PRS signals with one of the GPS code M signals.

4. The military, industrial and commercial stakes

There are several reasons why the Americans oppose the overlay of the two signals.

(a) Military reasons

The United States considers that any civilian satellite navigation signal may be used for hostile or even terrorist
purposes against national or NATO interests. In order to counter that threat, the US and soon NATO plan to
develop an electronic warfare system called Navwar, that can locally jam civilian signals without interfering with
the GPS M code.

In accordance with that approach, the Americans also want to be able to jam the Galileo signal where circum-
stances dictate, since it is not a military signal. However, the use of a single frequency band with the same
modulation by one of the two PRS signals and one of the two GPS M code signals does not allow this jamming
system to be applied directly. It would indeed be technically difficult to jam one of the two signals selectively
without degrading the other.

The following political question therefore arises: does overlay create unacceptable risks for the EU and NATO and
how can any such risks be managed?

(b) Industrial and commercial reasons

It cannot be ruled out that, in 10 years' time, the GPS M code could be used not only for military purposes as it
is today, but also by other categories of users, such as coastguards, customs, etc., in many countries. Over 25
countries already use it. The potential market probably embraces hundreds of categories of users.

However, the Galileo PRS signal is also designed to meet the needs of all applications in the European Union
requiring secured signals (transport of nuclear materials, customs, police, etc.).

Even though Galileo is a civilian system, the European Union's PRS is an encrypted signal potentially as well
protected as the GPS military signal.

Since it is impossible to selectively jam a navigation signal using the same modulation and frequencies as another
signal without seriously degrading it, allowing a full overlay with the same modulation of one of the two Galileo
PRS signals with one of the two GPS M code signals means that the United States must reach an agreement with
the Europe Community to ensure that its policy on any exports of PRS receivers is coordinated and compatible
with theirs.

II. ARGUMENTS FOR OVERLAY

1. Technical justification

(a) The need to overlay the GPS signal

In order to attain metre precision and reject interference, the Galileo PRS signal must use two frequency bands
that are wide enough and spaced far enough apart. It was this frequency configuration, which was also adopted
for the most demanding signals of the American GPS and Russian Glonass systems, that led to the choice of the
Galileo signal scenario (1).

Taking account of international telecommunications regulations, the only available frequencies are in band L1
which is reserved for satellite navigation. This band is already used by GPS and Glonass for their top-level signals.
The frequency band used by the PRS signal must therefore be overlaid on either the GPS or the Glonass band.
The latter is ill advised for technical reasons since Glonass is based on a totally different design from GPS and
Galileo.

As stated earlier, the Galileo PRS signal in the L1 band is in any case overlaid by the GPS signals in the same
band, without leading to any degradation of performance according to ITU criteria, as is demonstrated by
i.e. a good
interference calculations. Overlaying automatically requires reciprocity between GPS and Galileo,
level of interoperability between the two systems (a similar level of interference, for example).

(b) Choice of signal type in band L1

The specifications of the Galileo PRS signal are defined so that they are flexible. There are two main options for a
signal located in the L1 high band, one using a signal with ‘BOC (10,5)’ type modulation, the other a ‘BOC (14,2)’
type signal. BOC (10,5) modulation involves a full overlay with one of the two GPS code M signals, whereas a
BOC (14,2) type signal corresponds to a 75 % overlay (6 MHz of code M overlaps with the 8 MHz allocated at
the World Radionavigation Conference held in 2000 in Istanbul).

The choice remains open but BOC (10,5) is the preferred option for the following reasons:

— this type of signal costs the same but is more efficient than BOC (14,2) modulation. The two GPS code M
signals and the PRS signal in the E6 medium-frequency band are of the BOC (10,5) type. If the European
Union were to give up this type of signal for Galileo PRS in band L1, we would end up with a less efficient
and less competitive system,

— it has not been proven that a BOC (14,2) signal can provide certain technical functions essential to the

smooth operation of a PRS receiver,

— a BOC (14,2) signal could be unilaterally jammed by the United States, which in practice would mean giving
them the right to control Galileo PRS users. On the other hand, the Americans would have no technical
means of jamming a BOC (10,5) signal that was fully overlaid on the GPS M code in band L1. Control of the
users of this signal would be exercised by an appropriate European body using encryption techniques.

(1) Scenario A.

15.10.2002

In order to respond to American concerns, the Commission suggested the choice of a generic signal, known as
BOC (n,m), in the high-frequency L1 band for one of the two PRS signals, leaving the modulation type flexible at
this stage of the project. However, of the available modulation types, BOC (10,5) is the most efficient.

2. Political arguments

(a) The European Union has the essential security know-how

Although a civilian signal, PRS will be restricted to certain strictly governmental applications and secured under
government control. The argument that the PRS signal should be jammed in the same way as the other Galileo
signals carried much less weight if that signal is appropriately secured (government encryption, users approved by
the European Union, service controlled by a European body).

Some EU Member States have the know-how to design and implement effective government encryption. The
resulting technology could be made available to the European authorities controlling the Galileo PRS signal.

(b) The need for mutual trust

Since October 1993, when the Memorandum of Understanding between the American Department of Defense
and the NATO member countries for access to the GPS encrypted navigation service was signed, a dozen
non-NATO countries and a few civilian administrations (American federal agencies and the Norwegian police,
for example) have had access to the service. However, the NATO member countries were never consulted on this
American policy of exporting a service which has become the main navigation system in the NATO Countries.
Similarly, the NATO member countries never worried about the possible consequences of that export policy for
NATO security because they knew that American and NATO interests were compatible and because they trust
the security mechanisms that the Americans have put in place for GPS.

Moreover, the choice of the GPS frequency band for the Galileo PRS signal was governed not only by technical
compatibility issues but also by a high level of trust in American security capabilities. This choice represents a
clear distinction between the secured signals (GPS M code and Galileo PRS) on the one hand and the unsecured
signals (all except M code and Galileo PRS) on the other. This split is compatible with the implementation of the
local jamming technology favoured by the United States and NATO.

The EU would like the US to show the same trust regarding its capability to implement a secure Galileo system.

Conclusion

The European Union acknowledges the wish of the United States to have a properly secured signal (M code) for military
and security reasons. The Commission's proposal takes account of both parties' security concerns, firstly by using
flexible modulation for the PRS code, which can be adapted as required, and by setting up a security structure to
monitor and control the use of the PRS code during the operational phase of Galileo. This security structure would be
an appropriate interlocutor for the American security bodies. The European Community is prepared to seek a political
agreement with the United States on the cooperation necessary between the two satellite navigation systems in
preparation for a crisis or in the event of a crisis.
