## Introduction

**Introduction**

**Who am I?**
- I work for Astrium, Europe’s largest space company
- Astrium is a founder member of Galileo Industries, an industry group:
- Acting as infrastructure prime for Galileo
- Preparing & promoting a PPP financing scheme for Galileo
- Supporting our EC and ESA customers on a number of Galileo initiatives
**What do I do?**
- Led industrial design team for the SIS last year, member of EC Signal Task Force, engineering lead on some UK studies, plus technical co-ordination between Astrium engineering & business teams
**What will I talk about?**
- Why Galileo? & what is it?
- Roadmap & Status Report
- Progress update (more technical)

## Why Galileo?

**Position and timing information is an essential part of everyday life**
- E112/E911, Global clock / time synchronisation, Financial transactions, Fleet & traffic management, M-Commerce, Location-based services
**A complementary system to GPS is essential for Europe**
- Offers significant macro-economic and social benefits for Europe
- Avoids economical and political European dependence on GPS
**A single satellite system ultimately limits market development**
- Need for redundancy (and certification) in safety critical applications
- Dual system enhances existing & emerging markets:   GPS only   Galileo+GPS
- 			Accuracy (95% availability)	  20m 	5m
- 			Availability (4m accuracy)	  10 % 	90 %
- Dual system enables the user to evaluate the achieved accuracy level even in urban areas
**Only Europe is capable of delivering a second system**

## Galileo Key Features

**Provides accurate & reliable Position, Velocity & Timing information**
- Equals or exceeds GPS IIF performance
- Comprises an open access service and restricted access services
- Restricted services offer guarantees & liability
- Provides continuous measure of PVT accuracy (Integrity)
**Global service, European-led under civil control**
- Independent but compatible and interoperable with GPS
- (Galileo+GPS) offers better availability than either alone
- Galileo is open to international partnerships
**Funded through Public-Private Partnership (PPP)**
- Basic infrastructure publicly funded
- Substantial investment from private sector (owner/operator)
- Services are designed to maximise the potential for revenue return

## Preferred Galileo Hierarchy

**Operate infrastructure**
**Deliver public services**
**Deliver commercial  services**

** ****Define Public Service****	****Requirements**
** ****Select Private Partner**
** ****Procure Services**

**Preferred Galileo Hierarchy**

## Roadmap

## Galileo Programme Status

**EU Council of Transport Ministers:**
**April, 2001**
- EC Released 100 M€ (with matching contribution from ESA)
- EC 5th Framework and ESA Phase B2 contracts, plus others...
- Interim management structure (EC / ESA) proposed; starts September
**June, 2001**
- Cost benefit analysis verified
- Preliminary services identified:
- Navigation services: Open, Safety-of-life, Commercial, Public regulated, & GNSS-1 augmentation
- Navigation-related services: Search and rescue, & Navigation related communications
- Tendering process initiated for business plan
- Enabler for long-term private sector involvement

## Technical Update – Signal (1)

**The preferred frequency plan and signal structure are being developed by the EC Signal Task Force**
- Expert body comprising Member States, EC/ESA, industry, academic and government advisors
- Has design authority, mandated from Programme Management Board
- Puts forward signal/frequency plans for international discussion where needed
- ...Leading to a formal SIS ICD
**Key signal scenarios are defined by STF and studied by ESA and industry under the Phase B2 contract **
- Galileo Industries is prime for B2 study
- Signal team comprising several companies in Europe is led by Astrium
**Teaser: see the STF and Astrium papers in the IoN A3 Session!**

## Technical Update – Signal (2)

**L5 (E5a in European filings)- high chip rate, low data rate, pilot tone**
- Improved reception indoors
**E5b- high chip rate, high data rate, pilot tone, integrity**
- Fast acquisition
**L5 & E5 can also be used for aviation**
- Complements GPS, has no common failure modes
**E6- high chip rate restricted access signal & possible 3****rd**** open signal**
**E2/L1/E1- Complex signal...**
- Wide Binary Offset Carrier, e.g. (14,2) plus central (2,2); pilot tones
- Can be used for aviation; combinations of the signals for open and/or restricted access

**STF discussion scenario (others are also being studied):**

## Technical Update – Signal (3)

**Now approaching 1****st**** key output of the ESA Phase B2 study (KPM)**
- Can speak about themes here, but can’t give results
**Current industrial activities include-**
- Review of scenarios
- Consolidate requirements documents, perform initial analysis & simulations
- Receiver models for multipath mitigation, DME interference etc.
- Navigation message definition
- Establish information content for navigation & integrity functions
- Signal definition
- Optimise signal parameters and message structure
- Update signal & message specifications
- Performance evaluation / payload impacts
- Looking at payload implementation, code & data performance, ionospheric effects, fading channels etc.

## Technical Update – Mission Consolidation & System Engineering

**Lead-in activity of Phase B2**
- Review and harmonise results & requirements from previous phase
- Next iteration of service definitions: Safety, Search & Rescue, Comms
- Perform system-level trade-offs:
- Integrity: (Global + regional) or (Europe + other regions)
- Affects architecture, satellite uplinks, SIS data rates, system cost
- Inclusion / exclusion of GPS integrity; EGNOS integration
- Affects architecture, SIS capacity, system cost
- Impact of signal accuracy update rate
- Sensitivity analysis of availability vs. Time-to-Alarm and SIS Accuracy validity
- Signal
- See previous slides

## Technical Update – Architecture (1)

## Technical Update – Architecture (2)

**Constellation**
- Medium Earth Orbit, 30 satellites (3 are spares)
- 56° inclination, circular orbits at approx. 27000 km altitude & 14 hr period
**Space Segment**
- Reviewing/updating design status to reflect requirements evolution
- E.g. incorporation of Search and Rescue payload into costing baseline
**Ground Control Segment**
- Assisting system level trade-offs; next stage is drill-down into specifications
**Integrity Determination/Dissemination Segment**
- Assisting system level trade-offs; next stage is drill-down into specifications
**User Segment**
- Support to system & signal activities

## What’s Next?

**Technical:**
- Phase B2 completes Q1 2002
- Status point on design maturity and cost
- Then progress to Risk Reduction
**Business:**
- PriceWaterhouseCoopers study into the business case and benefits of Galileo
- Concludes Q4 2001
- Transport Council will be invited to approve the formation of a Joint Undertaking
- Dec 2001
- Implementation of a Long Term procurement strategy
