Hot Bird 8, 9, 10 / Atlantic Bird 4A

Eutelsat and EADS ASTRIUM announced in September 2003 the signature of a contract for the construction the Hot Bird 8 broadcast satellite which will be launched in early 2006 by Arianespace on-board an Ariane 5 rocket.

With 64 transponders that can be operated simultaneously, of which 58 transponders will operate at full power for most of the satellite’s lifetime, Hot Bird 8 is the largest satellite yet ordered by Eutelsat. It will join the company’s constellation of HOT BIRD broadcasting satellites at 13 degrees East that provide television, radio and interactive services to almost 100 million cable and satellite homes in Europe, North Africa and the Middle East.

Hot Bird 8’s mission is to replace existing Hot Bird capacity and to join Hot Bird 7A in bringing in-orbit sparing to a level where 13 degrees East can maintain its reputation as one of the most secure multi-satellite video neighbourhoods. The satellite has been designed to cover all 102 Ku-band transponders/frequencies at 13 degrees East which means that it can substitute any transponder on the other Hot Bird satellites.

EADS Astrium, as prime contractor for Hot Bird 8, will design and build the satellite and supply both the payload and the platform. The spacecraft will have a launch mass of less than 5 tons, a solar array span of 45 meters once deployed in orbit, and a spacecraft solar array power of almost 14 kW at end of life. It will provide commercial services for a minimum of 15 years.

Hot Bird 8 is based on the Eurostar-3000 version of the Eurostar family, already ordered by five major satellite operators. 34 Eurostar spacecraft have been ordered to date, of which 23 have already been launched and have proven highly reliable in operational service.

An identical Hot Bird 9 was contracted in May 2006 for a launch in 2008.

The Hot Bird 10, which was ordered in October 2006 is also identical to Hot Bird 8 and Hot Bird 9 with the same mission capacity. It was initially comissioned as Atlantic Bird 4A at 7°W, but will revert to it's Hot Bird 10 designation when Atlantic Bird 7 becomes operational.
