Mission Details

Skynet 4C

Skynet is a family of military communications satellites, now operated by Astrium Services on behalf of the UK Ministry of Defence, which provide strategic communication services to the three branches of the British Armed Forces and to NATO forces engaged in coalition tasks. The satellites were operated by Paradigm Secure Communications until October 2012 when the organisation was rebranded to Astrium Services.

Eutelsat 2F1

In 1990 Eutelsat began the deployment of the second generation Eutelsat spacecraft procured directly from Aerospatiale and based on the Spacebus-2000 design. Each Eutelsat 2 spacecraft supports 16 transponders (with eight spares) operating at 14/11 GHz and 50 W output power. In orbit, the spacecraft spans 22.4 m across the two rectangular solar arrays which generate up to 3.5 kW. Eutelsat 2 employs two 1.6 m diameter multifeed reflectors, one on each side of the spacecraft bus.
