Arianespace release
Another successful Ariane launch:
SPAINSAT and HOT BIRDTM 7A in orbit
On Saturday evening, March 11, Arianespace placed two satellites into
geostationary transfer orbit: SPAINSAT for the Spanish military operator
Hisdesat, and HOT BIRDTM 7A for the European operator Eutelsat.
First launch of 2006: 22nd successful Ariane 5 launch, 12th in a row
Today's successful Ariane 5 launch, the 12th in a row and 22nd overall,
shows that Arianespace launch services are more than ever the best fit
with the needs of operators around the world.
In just over six months, Arianespace has used five Ariane 5s to launch
nine satellites - sending more than 33 tons of total payload into
geostationary transfer orbit!
Today, Ariane 5 is the only commercial launcher in service capable of
simultaneously launching two payloads and giving customers the
performance, flexibility and competitiveness they expect.
Launches for two prestigious operators
Following the launch of XTAR-Eur in February 2005, Hisdesat once again
called on the European launcher for its new SPAINSAT satellite. Spainsat
will take over for the Secomsat military payloads launched by
Arianespace in 1992 and 1993 on the Hispasat 1A and 1B satellites.
SPAINSAT is the 25th military payload to use an Ariane launcher.
Arianespace and Eutelsat have built up a very fruitful, uninterrupted
partnership over the last 22 years. More than half of Eutelsat's fleet
has been orbited by the European launcher. Hot Bird 7A is the 21st
Eutelsat satellite launched by Arianespace.
SPAINSAT /HOT BIRDTM 7A mission at a glance
The mission was carried out by an Ariane 5 ECA launcher from Europe's
Spaceport in Kourou, French Guiana. Liftoff was on Saturday, March 11 at
07:32 p.m. local time in Kourou (05:32 p.m. in Washington, D.C., 22:32
GMT and 11:32 p.m. in Paris and Madrid).
Provisional parameters at injection of the cryogenic upper stage (ESC-A)
were:
Perigee: 248.7 km for a target of 248.6 km (±3)
Apogee: 35,938 km for a target of 35,966 km (±160)
Inclination: 4.98 degrees for a target of 5.00 degrees (±0.06º)
SPAINSAT is the first Spanish satellite dedicated to secure government
communications. Its operator is Hisdesat, a company founded in 2001 by
Hispasat, INSA (a wholly-owned subsidiary of INTA), EADS CASA Espacio,
Indra and Sener. Its first customer is the Spanish ministry of defense.
Weighing about 3,700 kg at launch, SPAINSAT was built by Space
Systems/Loral in Palo Alto, California. It will be positioned at 30
degrees West, over the Atlantic, and will have 13 X-band transponders
and one Ka-band transponder. Spanish industry will supply several major
subassemblies, plus the ground segment.
HOT BIRDTM 7A will be located at 13 degrees East, Eutelsat's flagship
orbital position for TV and radio broadcasting. Built by Alcatel Alenia
Space, HOT BIRDTM 7A will weigh about 4,100 kg at launch. Fitted with 38
Ku-band transponders, it is designed to renew current capacity and
provide redundancy for the HOT BIRD family at this orbital position.
Eutelsat now transmits more than 850 television channels and 550 radio
stations from this spot to some 110 million households in Europe, the
Middle East and North Africa.
