A DUAL LAUNCH FOR TWO DIRECT TV BROADCAST SATELLITES

Arianespace will orbit two satellites dedicated to direct-to-home (DTH) television

broadcasting on its fourth launch of the year: ASTRA 1N for the Luxembourg-based

operator SES Astra, and BSAT-3c/JCSAT-110R for the American manufacturer

Lockheed Martin Commercial Space Systems, as part of a turnkey contract for the

Japanese operators B-SAT Corporation and SKY Perfect JSAT Corporation.

The choice of Arianespace by leading space communications operators and

manufacturers is clear international recognition of the company’s excellence in launch

services. Based on its proven reliability and availability, Arianespace continues

to confirm its position as the world’s benchmark launch system.

Ariane 5 is the only commercial satellite launcher now on the market capable

of simultaneously launching two payloads and handling a complete range of missions,

from launches of commercial satellites into geostationary orbit, to dedicated launches

into special orbits.

Over the last two decades, Arianespace and SES have developed an exceptional

relationship. ASTRA 1N will be the 34th satellite from the SES group (Euronext Paris

and Luxembourg Bourse: SESG) to use the European launcher. SES operates the

leading direct-to-home (DTH) TV broadcast system in Europe, based on its Astra

satellites, serving more than 135 million households via DTH and cable networks.

Built by Astrium using a Eurostar E3000 platform, ASTRA 1N will weigh 5,350 kg at

launch. Fitted with 52 active Ku-band transponders, ASTRA 1N will be positioned at

19.2 degrees East. It will deliver DTH TV broadcast services across Europe, and offers

a design life of about 16 years.

BSAT-3c/JCSAT-110R is the 26th satellite for which Japanese operators have chosen

the European launcher, and the 41st Lockheed Martin-built platform to be launched

by Arianespace.

BSAT-3c/JCSAT-110R was built by Lockheed Martin Commercial Space Systems at its

plant in Newtown, Pennsylvania, using an A2100 A platform. Weighing 2,910 kg at

launch, it will be positioned at 110 degrees East longitude in geostationary orbit, and

offers a design life exceeding 16 years. BSAT-3c/JCSAT-110R is fitted with 2 sets of

twelve 130 Watt Ku-band transponders, and is primarily designed to provide direct TV

broadcast links for all of Japan.

3. Launch countdown and flight events

The countdown comprises all final preparation steps for the launcher, the satellites and the launch site. If it

proceeds as planned, the countdown leads to the ignition of the main stage engine, then the two boosters, for

a liftoff at the targeted time, as early as possible in the satellites launch window.

The countdown culminates in a synchronized sequence (see appendix 3), which is managed by the control

station and onboard computers starting at T-7 minutes.

If an interruption in the countdown means that T-0 falls outside the launch window, then the launch will be

delayed by one, two, or more days, depending on the problem involved, and the solution developed.

The launcher’s attitude and trajectory are totally controlled by the two onboard computers, located in the

Ariane 5 vehicle equipment bay (VEB).

7.05 seconds after ignition of the main stage cryogenic engine at T-0, the two solid-propellant boosters are

ignited, enabling liftoff. The launcher first climbs vertically for 6 seconds, then rotates towards the East. It

maintains an attitude that ensures the axis of the launcher remains parallel to its velocity vector, in order to

minimize aerodynamic loads throughout the entire atmospheric phase, until the solid boosters are jettisoned.

Once this first part of the flight is completed, the onboard computers optimize the trajectory in real time,

minimizing propellant consumption to bring the launcher first to the intermediate orbit targeted at the end

of the main stage propulsion phase, and then the final orbit at the end of the flight of the cryogenic upper stage.

The main stage falls back off the coast of Africa in the Atlantic Ocean (in the Gulf of Guinea).

On orbital injection, the launcher will have attained a velocity of approximately 9848 meters/second, and will

be at an altitude of about 660 kilometers.

The fairing protecting the ASTRA 1N and BSAT-3c/JCSAT-110R spacecraft is jettisoned shortly after the boosters

are jettisoned at about T+192 seconds.

Appendix 2. Launch environment conditions

Acceptable wind speed limits at lift-off range from between 7.5 m/s to 9.5 m/s according to the wind direction.

The most critical is a northerly wind. For safety reasons, the wind’s speed on the ground (Kourou), and at a high

altitude (between 10,000 and 20,000 m) is also taken into account.

Appendix 3. The synchronized sequence

The synchronized sequence starts 7 mn before ignition (T-0), it is primarily designed to perform the final

operations on the launcher prior to launch, along with the ultimate checks needed following switchover to

flight configuration. As its name indicates, it is fully automatic, and is performed concurrently by the onboard

computer and by two redundant computers at the ELA 3 launch complex until T-4 seconds.

The computers command the final electrical operations (startup of the flight program, servocontrols, switching

from ground power supply to onboard batteries, etc.) and associated checks. They also place the propellant and

fluid systems in flight configuration and perform associated checks. In addition, they handle the final ground

system configurations, namely:

• Startup of water injection in the flame trenches and jet guide (T-30 sec).

• Hydrogen aspiration for chilldown of the Vulcain engine in the jet guide (T-18 sec).

• Burnoff of hydrogen used for chilldown (T-5.5 sec).

At T-4 seconds, the onboard computer takes over control of final engine startup and lift-off operations:

• It starts the ignition sequence for the Vulcain main stage engine (T-0).

• It checks engine operation (from T+4.5 to T+7.3 sec).

• It commands ignition of the solid boosters for immediate lift-off at T+7.3 seconds.

Any shutdown of the synchronized sequence after T-7 mn automatically places the launcher back in its

T-7 min configuration.

Arianespace was founded in 1980 as the world’s first launch Service & Solutions company. Today, Arianespace has 21

shareholders from ten European countries (including French space agency CNES with 34%, Astrium with 30%, and all

European companies participating in the construction of Ariane launchers).

Since the outset, Arianespace has signed more than 300 launch contracts and launched 294 satellites. More than two-thirds

of the commercial satellites now in service worldwide were launched by Arianespace.

The company posted sales exceeding 900 million euros in 2010.

As of January 1, 2011, Arianespace had 331 employees, working at the company’s headquarters in Evry (near Paris), the Guiana

Space Center in French Guiana, where the Ariane, Soyuz and Vega launch pads are located, and offices in Washington, D.C.,

Tokyo and Singapore.

Arianespace offers launch Service & Solutions to satellite operators from around the world, including private companies and

government agencies. These Service & Solutions call on three launch vehicles:

• The Ariane 5 heavy launcher, operated from the Guiana Space Center in Kourou, French Guiana.

• The Soyuz medium launcher. Currently in operation at the Baikonur Cosmodrome in Kazakhstan under the responsibility

of Starsem, a Euro-Russian subsidiary of Arianespace, it will be launched from the Guiana Space Center starting in 2011.

• The Vega light launcher, to be launched from the Guiana Space Center starting in 2011.

With its family of launchers Arianespace won over half of the commercial launch contracts up for bid worldwide in the last

two years. Arianespace now has a backlog of more than 40 satellites to be launched.

The Guiana Space Center: Europe’s Spaceport

For over 30 years, the Guiana Space Center (CSG), Europe’s Spaceport in French Guiana, has offered a complete array of

facilities for rocket launches.

It mainly comprises the following:

• CNES/CSG technical center, including various resources and facilities that are critical to launch base operations, such as

radars, telecom network, weather station, receiving sites for launcher telemetry, etc.

• Payload processing facilities (ECPU), in particular the S5 facility.

• Ariane launch complexes (ELA), comprising the launch zone and launcher integration buildings.

• Various industrial facilities, including those operated by Regulus, Europropulsion, Air Liquide Spacial Guyane and Astrium,

which contribute to the production of Ariane 5 elements. A total of 40 European manufacturers and local companies are

involved in operations.

The Guiana Space Center is preparing to welcome two new launch vehicles, Soyuz and Vega. The construction of the Soyuz

launch complex (ELS) and of the Vega launch complex (SLV) have now been completed.

Europe’s commitment to independent access to space is based on actions by three key players: the European Space Agency

(ESA), French space agency CNES and Arianespace.

ESA has helped change the role of the Guiana Space Center, in particular by funding the construction of the launch complexes,

payload processing buildings and associated facilities. Initially used for the French space program, the Guiana Space Center

has gradually become Europe’s own spaceport, according to the terms of an agreement between ESA and the French

government.

To ensure that the Spaceport is available for its programs, ESA takes charge of the lion’s share of CNES/CSG fixed expenses,

and also helps finance the fixed costs for the ELA launch complexes.

French space agency CNES plays several roles at the Space Center.

• It designs all infrastructures and, on behalf of the French government, is responsible for safety and security.

• It provides the resources needed to prepare the satellites and launcher for missions.

Whether during tests or actual launches, CNES is also responsible for overall coordination of operations. It collects and

processes all data transmitted from the launcher via a network of receiving stations, to track Ariane rockets throughout their

trajectory.

In French Guiana, Arianespace is the contracting authority in charge of operating the family of three launchers, Ariane, Soyuz

and Vega.

Arianespace supervises the integration and functional checks of the Ariane launcher, built by Astrium as production prime

contractor, in the Launcher Integration Building (BIL). It then carries out acceptance tests of the launcher at the same time as

satellite preparations in the Payload Preparation Complex (EPCU), operated by the Guiana Space Center (CSG). Arianespace

next oversees final assembly of the launcher and integration of satellites in the Final Assembly Building (BAF), followed by

transfer of the launcher to Launch Zone No. 3 (ZL3), and then final countdown and liftoff from Launch Complex No. 3 (CDL3).

Arianespace has created a top-flight team and array of technical resources to get launchers and satellites ready for their

missions. Building on this unrivalled expertise and outstanding local facilities, Arianespace is now the undisputed benchmark

in the global launch services market.
