Series of military communications satellites built by Lockheed and also known as ES-8A. The operational constellation consisted of three satellites in a near geostationary orbit. They were equipped with transponders operating in the 45/21 GHz, to service mobile military terminals, 225/400 MHz and 60 GHz bands, the latter for satellite to satellite communications.
The Milstar team is led by the MILSATCOM Joint Program Office at the Air Force Space and Missile Systems Center in El Segundo, CA. TRW Space and Electronics Group provides the low data rate payload for the satellite. Hughes Aircraft Company is providing the medium data rate payload for Milstar Block 2. The major technologies aboard are on-board signal processing and routing and inter-satellite links.
US military communication system. To provide secure worldwide wartime telecommunications. The satellites apply the switchboard in space concept and provide on-board signal processing, signal routing, resource control, crossbanding and satellite crosslinks.
Milstar-1 was also known as Development Flight Satellite (DFS)-1 and, in addition to the normal payload, may have carried a technology experiment as part of the Brilliant Pebbles programme. With the introduction of Milstar 2-1 the capacity was increased to 32 transponders in the 45/21 GHz band whilst the Medium Data Rate payload and a crosslink capacity at 60 GHz were introduced on Milstar 2-2 and Milstar 2-3 respectively.
