Low Earth OrbitThe Mercury (MC) series, although known to the public as 'Advanced Vortex', are the latest generation of USAF ELINT/SIGINT satellites. They were focussed on communications intelligence (COMINT), focused at strategic level communications, but had the capability added to intercept also missile telemetry. These satellites were launched under the designation Program 7500 and were part of NRO's Program A.
Geostationary OrbitTUBSAT-N and Tubsat-N1 are two nanosatellites, which were launched on the 7th of July 1998 as a satellite cluster from a submarine with a russian Shtil-1 rocket in the Barents Sea. All systems are working well and the satellites are in a excellent overall condition. The satellites were separated in orbit via telecommand. Both satellites were developed at the Technical University of Berlin and the complete project was financed by DLR.
