NEXTSat, or Next Generation Satellite and Commodities Spacecraft (NEXTSat/CSC) is an American technology demonstration satellite which was operated as part of the Orbital Express programme. It was used as a target spacecraft for a demonstration of autonomous servicing and refueling operations performed by the ASTRO satellite. Launched in March 2007, it was operated for four months, and then deactivated in orbit.
Advanced Extremely High Frequency (AEHF) is a constellation of communications satellites operated by the United States Space Force. They are used to relay secure communications for the United States Armed Forces, the British Armed Forces, the Canadian Armed Forces, the Netherlands Armed Forces and the Australian Defence Force. The system consists of six satellites in geostationary orbits. The final satellite was launched on 26 March 2020. AEHF is backward compatible with, and replaces, the older Milstar system and will operate at 44 GHz uplink and 20 GHz downlink. The AEHF system is a joint service communications system that provides survivable, global, secure, protected, and jam-resistant communications for high-priority military ground, sea and air assets.
