The Society of Japanese Aerospace Companies

Prologue
The Society of Japanese Aerospace Companies (SJAC) is the solepublic entity representing the interests of the Japanese aerospaceindustry. SJAC was established with the purpose of contributing
to the expansion of the Japanese aerospace industry, together withthe overall improvement of national welfare −through production
enhancement and trade expansion of aerospace related products−,
and contributing to the sound growth of the aerospace industry as
a whole.
SJAC was founded in 1952, in the year the Japanese aviationindustry reopened, as a private forum for aircraft industrialists.
Over the years, companies involved with space development
gradually began to include themselves as well. SJAC was
reorganized in 1974 as The Society of Japanese Aerospace
Companies, and has grown steadily to become what it is today. In
addition, SJAC joined the International Coordinating Council of
Aerospace Industries Associations (ICCAIA) in 1972.
SJAC is active in the International Civil Aviation Organization(ICAO) and ICCAIA, and continually works on increasing bothunderstanding and cooperation with overseas aerospace industrial
societies including the AIA in the U.S., the ASD in the EU, the
ADS in the U.K., GIFAS in France and AIAC in Canada.
SJAC is now comprised of approximately 140 member companies,
and these members represent a majority of the companies engaged
in the manufacturing, repairing and trading of aircraft, satellites,
launch vehicles and related equipment in Japan.
This catalog “Directory of Japanese Space Products & Services

H3 Launch Vehicle
The H3 Launch Vehicle is Japan's new generation
flagship rocket that achieves high flexibility, highreliability, and a high level of cost/performancewith the goal of leading in Space Transportation
Technology. With two types of fairing, two or three
first-stage engines (LE-9), and zero, two or foursolid rocket boosters (SRB-3) depending on therequired configuration, the H3 is offered in several
product lines according to the dimensions, weight,
and injection orbit of the mission payload. The
capability of launching to a geostationary transfer
orbit (GTO) is also the highest ever, exceeding thatof the existing H-IIA and H-IIB Launch Vehicles.
The H3 is currently being developed as a successor
to these launch vehicles based on their remarkable
past results, and it will provide the government withthe ability to act independently to access space andlaunch satellites and probes. The Japan Aerospace
Exploration Agency (JAXA*), Mitsubishi Heavy
Industries (MHI) as the prime contractor, and otherrelated companies are all working on improving theentire system in order to complete this flexible andreliable rocket to be offered at an attractive price.

abolished in 2006. The first experimental model
was launched in 2013, and further improvements
were completed with Epsilon-2 and Epsilon-3.
Epsilon-4 supported a multi-satellite mountstructure as an optional configuration, and it
was successfully launched with seven satellites
simultaneously in January 2019. This technology
was developed to make the Epsilon Launch
Vehicle internationally competitive in the launchmarket because the demand for launching
multiple mini-/micro-satellites and/or CubeSats
together is gradually increasing globally.
The purpose of new Epsilon S Launch Vehicle
Project is to expand the scale of Japan’s spacetransport industry and to maintain the ability
to act independently to access space througha synergistic effect with the H3 launch vehicle
program. A demonstration launch of the Epsilon S
is currently scheduled for FY2023.

H-II Transfer Vehicle "KOUNOTORI" (HTV)The H-II transfer vehicle “KOUNOTORI” (HTV) is an
unmanned orbital transfer vehicle that measures
10 m in length and 4.4 m in maximum diameter.
The vehicle weighs 16.5 tons and can carry a 6-ton
payload in logistic carriers. HTV has two typesof logistics carrier: a pressurized section wherecrew members can work when the HTV is berthedto the ISS, and an unpressurized section that
accommodates Kibo's exposed facility payloads onthe exposed pallet.

The asteroid explorer Hayabusa 2 was planned basedon the heritage of Hayabusa (MUSES-C) that returned
to Earth in June 2010. Hayabusa brought back samples
from the asteroid “Itokawa” to research the origin of thesolar system. Hayabusa 2 targets the C-type asteroid“Ryugu” to continue this purpose by appending theexperience acquired from the Hayabusa mission.
To learn more about the origin and evolution of the solar
system, it is important to investigate a C-type asteroid,
which is the target of Hayabusa 2, because it is amore primordial body than Itokawa, which is an S-type
asteroid, and is considered to contain more organic or
hydrated minerals. Minerals and seawater, which form
the Earth as well as materials for life, are believed to bestrongly connected in the primitive solar nebula in theearly solar system.

Earth Observation
Satellites
ASNARO-2
NEC’s small radar satellite, Advanced Satellitewith New system Architecture for Observation-2"ASNARO-2", was launched from the JAXA
Uchinoura Space Center on January 18, 2018.
ASNARO-2 was developed by NEC Corporationas part of a project funded by Japan’s Ministry of
Economy, Trade and Industry. JAXA, who is NEC
Corporation’s contractor, is in charge of the launch
operations of ASNARO-2.
ASNARO-2's radar sensor has successfully
captured details of ground conditions, such as the
movement of lava around a crater, even though it
was obstructed by smoke, something that is difficult
for conventional optical sensors to observe.

upgrading performance compared to that of theprevious ALOS. ALOS-3 observations regularly
cover all of the land areas of not only Japan but
also across the whole world.
The purpose of ALOS-3 is to become one of the key
tools for disaster management and countermeasuresof the central and local governments. In addition tothat, a system for product distribution has also beendeveloped to deliver images to users swiftly of both
before and after a disaster.
This sensor, which is very challenging to achieve,
has been developed thanks to our technical
heritage accumulated through our experience inmanufacturing large optical systems and highperformance detectors.

ALOS-4 is a satellite that observes the Earth's
surface using its onboard phased array typeL-band synthetic aperture radar (PALSAR-3). The
L-band radar technology has been continuously
developed in Japan. With observation performance
improved even further compared to the predecessor
PALSAR-2 aboard the ALOS-2, JAXA and Mitsubishi
Electric Corporation as the prime contractor
are developing a satellite that covers both highresolution and a broader observation range.

Directory of Japanese Space Products & Services 2023-2024

The ALOS-4 will be equipped with the highperformance satellite Automatic Identification
System for ships (AIS) receiver to be named the
SPace based AIS Experiment (SPAISE3). Effective
countermeasures against radio wave interference
regions are taken for the SPAISE3 with multiple
antennas and ground-based data processing.
SPAISE3 development is JAXA's ongoing project incooperation with NEC Corporation.

The Earth Clouds, Aerosols andRadiation Explorer (EarthCARE)
EarthCARE is an earth observation satellite thatJapan and Europe have been jointly developing.
Using its four sensors (Cloud Profiling Radar,
Backscatter Lidar, Multi-Spectral Imager andBroadband Radiometer), clouds and aerosols (small
particles like dust and dirt that exist in the earth's
atmosphere) will be observed on a global scale toimprove the accuracy of climate change predictions.
With the EarthCARE mission, observations will be
carried out on the distribution of cloud particles
and aerosols in the vertical direction and speed
measurements will be performed on cloud particles
ascending and descending. Through this, themechanism of radiation balance in the interaction
between clouds and aerosols can be solved andimprovements in climate change predictions are
expected.

Quasi-Zenith Satellite System (QZSS)QZSS is a Japanese satellite positioning systemcomposed mainly of satellites in quasi-zenith orbits(QZO). These satellites travel in a geosynchronous
orbit at an inclination of 45 degrees in order topass near the zenith over Japan, thus providing
seamless service irrespective of geographicalf e a t u re s . T h e y w i l l s i g n i f i c a n t l y i m p ro v e t h eaccuracy of positioning in areas where GPS signals
are not fully received due to interference causedby skyscrapers and mountainous terrain. Thesesatellites provide highly accurate centimeter-level
positioning information.
The first quasi-zenith satellite was launched in
September 2010. Three additional satellites werelaunched consecutively starting in 2017. QZSS(Michibiki) became a four-satellite constellationin 2018, and three satellites became visible at all
times from locations in the Asia-Oceania region.
QZSS can be used in combination with GPS,
ensuring a sufficient number of satellites for stable,
high-precision positioning.

Geostationary
Satellite
Engineering Test Satellite-9 (ETS-9)
ETS-9 is a demonstration satellite for realizing next
generation geostationary communication that will
be internationally competitive in the 2020s. JAXA
has been working together with Mitsubishi Electric
Corporation to be a prime manufacturer from thedesign phase in order to obtain highly competitive

satellite bus technology in the global market.
ETS-9 employs all-electric satellite technology andelectric propulsion, such as ion-engine and hallthruster, has been chosen instead of chemical
propulsion to transfer the satellite to a geostationary
orbit after separation from a launch vehicle. Thisapproach will significantly reduce propellant weight,
thus allowing heavier communication components,
and reducing the launch cost depending on theweight. Unfortunately, electric propulsion has a
disadvantage in that the impulsion is smaller thanwith chemical propulsion, so JAXA will improve thisnegative point to shorten the orbit raising period asmuch as possible.
ETS-9 will support a geostationary GPS receiver toenable autonomous control of its orbit by ingesting
its orbit information through the receiver to reduce
the workload of satellite operators. Furthermore, itwill verify the function of the loop heat pipe (LHP)
that dissipates the significant heat generated by the
25 kW or more of power consumed by the mission
components.

Payload Fairing

Payload Adapter

Payload fairing is a structure installed on the top of alaunch vehicle to protect payloads from aerodynamic
heating, acoustic noise and vibration during launch. Aftera launch vehicle leaves the earth’s atmosphere, a fairing
is separated into two and is jettisoned. Kawasaki hasdeveloped many types of payload fairings; long type (L)and short type (S) for H3 launch vehicle, 4S, 5S and 4/4D
for H-IIA launch vehicle, 5S-H for H-IIB launch vehicle,
and the one for Epsilon rocket. Type 4S is 4m in diameterfor single launch, type 5S is 5m in diameter for single
launch, type 4/4D is 4m in diameter for dual launch and
5S-H is 5m in diameter for the HTV (H-II Transfer Vehicle).
The Epsilon rocket fairing is 2.5m in diameter for single
launch. For the mission modification, access doors,
acoustic blankets, internal antennas and RF windows areavailable according to user’s requirements. All fairings
operated successfully in the past flights.

A payload is mounted on the launch vehicle using a
payload adapter which has a separation system. Kawasaki
has several types of payload adapters; model 1194M,
1666MA and 239M. These numbers indicate the diameterof the interface with the payload. They have a separation
system with clamp bands and separation springs. In
addition, Kawasaki has developed new model “Simple
PAF” for small satellites. Simple PAF features low cost,
low separation impact and excellent operability.

Mitsubishi Electric's space technology includes the
manufacture and implementation of satellites, satellite
components, and ground systems. Over the past four
decades, we have completed more than 650 satellite
projects for communications concerns, government
agencies, and other large-scale clients that makeus the leading company of space systems in Japan.
Also, Mitsubishi Electric can manufacture satellites
throughout from designing to assembling and testing.
This is because of the varieties of facilities we own
including a space chamber, compact antenna test range,
acoustic chamber, and vibration table. We announced
in February 2020 that it has completed constructionof a new facility for the production of satellites at thecompany's Kamakura Works. Together with existing
facilities, Mitsubishi Electric's combined annual capacity
will increase to 18 satellites, up from 10 at present,
which will enable the company to satisfy the growing
demand for governmental satellites in Japan andcommercial communication satellites worldwide. We
have a distinct advantage when it comes to designing,assembling, launching and controlling satellites because
we excel in the solar array panel, heat pipe panel, Liion battery, and ground station system technologies thatmake satellites practical to own and operate.

Satellite systems
Mitsubishi Electric was the first Japanese company totake part in a satellite project in 1960's with Intelsat series.
Since then, decades of participation in satellite projects
and the successful results have brought Mitsubishi Electricto the forefront of the industry. Mitsubishi Electric has
been manufacturing virtually every kind of satellites ofJapan Aerospace Exploration Agency (JAXA), and with thetechnology fostered and R&D efforts in the field, Mitsubishi
Electric has developed DS2000 standard geostationary
satellite bus platform based on JAXA’s ETS-8. DS2000 has
now 17 flight records with 4 in production as of August 2022.
An original program management system developed basedon years of experience in the communications satellite

business allows customers to access design data, andrequest changes during development through testing. Thishigh level of visibility ensures each platform is tailored toexact requirements and is completed in time to meet thedelivery schedule, thus allowing DS2000 to meet the needsof communications satellite operators around the world. On
top of that, in response to recent requirement in the market
for new high-power, high-throughput communications
satellites. Mitsubishi Electric has placed top priority on
developing a world-class, 25kW-output, all-electric satellite
bus system through the Engineering Test Satellite-9 incollaboration with JAXA.

Engineering Test Satellite-9

Ground systems
Mitsubishi Electric first took part in the ground system in
1960’s and since then we have distinct records in the fieldsuch as the 64m antenna in Usuda Deep Space Center of
JAXA, 45m antenna in Nobeyama Radio Observatory of
National Astronomical Observatory of Japan(NAOJ), and the
54m antenna in Misasa Deep space station of JAXA. We
have been contributing to the development of astronomy
through developing/manufacturing numbers of optical andradio telescopes including 8.2m Subaru Telescope (oneof the largest of its kind in the world) in Hawaii, Atacama
Large Millimeter / submillimeter Array (ALMA) and Atacama
Compact Array (ACA) in Chile.

”Himawari-8/9”

QZSS(Quasi-Zenith Satellite System) is a Japanese satellite
positioning system composed of three satellites in quasizenith orbit and one in geostationary orbit. QZSS will
significantly improve the accuracy of positioning in areas
where signals from GPS Satellites are not fully received due
to skyscrapers or mountains. The first quasi-zenith satellite“Michibiki” (QZS-1) was successfully put into orbit in 2010,
and in 2017, QZS-2, 3 and 4 succeeded. In addition, in
2021, the QZS-1R, the successor to the QZS-1, succeeded.
QZSS becomes a four-satellite constellation in 2018, andthree satellites have been visible at all times from locationsin the Asia-Oceania regions. Ensuring a sufficient number ofsatellites for stable, highprecision positioning, QZSS could
been used in an integrated way with GPS.

Solid propellant
Rocket propellant is composed of fuel and oxidants tomaintain its combustion in space. NOF develops andproduces various types of solid propellant. NOF has
provided solid propellant for all Japanese rockets, stretchingback to 1955 when "pencil rocket" was developed. As
rockets grew in size, they required propellant giving higher
performance. In response, NOF has carried out researchand development of new type of propellants and introduced
new and improved manufacturing technologies, production
facilities and equipment to ensure the reliability of its
products. Currently, NOF has two locations associatedwith rocket production: Taketoyo Plant in Aichi Prefecture,
which manufactures propellant for S-310 and S-520

rockets, used for scientific research; and Tanegashima
Works in Kagoshima Prefecture, which produces propellant
for SRB-A solid rocket boosters used on H-IIA and H-IIB
rockets. Boasting the world's largest solid propellant
mixer, Tanegashima Works can efficiently manufacture
largescale solid rocket boosters. NOF makes an effort forthe development of Solid propellant for H3 rocket following
H-IIA and H-IIB rockets.

Applications
Solid propellant: For S-310 rocket, S-520 rocket, Epsilon
rocket, SRB-A used on the H-IIA / H-IIB rocket
Igniters: For all types of rockets.
