Skynet 5A is the first in a series of new-generation Skynet military communications satellites, used by the British Ministry of Defence.[1] It was launched aboard an Ariane 5 carrier rocket at 22:03 GMT on 11 March 2007.[2][3]

Launch[edit]

Skynet 5A was one of two payloads orbited by the first Arianespace Ariane 5 launch of 2007. India's INSAT 4B communications satellite was launched on the same rocket.

It was originally planned for launch on 10 March, but due to a problem with a sensor controlling the launch pad water deluge system, the launch was delayed one day.

Construction[edit]

Skynet 5A was built by EADS Astrium, who also selected Ariane 5 as the carrier rocket to launch all three Skynet 5-series satellites. Their design is based on the Eurostar E3000 satellite bus.

Use[edit]

Skynet 5A is being used to provide secure communications services for the British armed forces and NATO. Skynet 5A had a launch mass of 4.7 tonnes, and operates with a payload power of 5 kilowatts, four times more than the previous-generation Skynet 4 satellites.

It is operated by Paradigm Secure Communications, a commercial organisation which is a wholly owned subsidiary of EADS Astrium, on behalf of the United Kingdom's Ministry of Defence.

Skynet 5A is located at 6 degrees East
