NOSS (Naval Ocean Surveillance System)

NOSS (Naval Ocean Surveillance System) was a system of United States Navy ocean surveillance satellites. NOSS detected the location of naval vessels using radio interferometry, and consisted of a main spacecraft and several subsatellites, linked by fine wires, several hundred meters apart. Eight of the spacecraft were placed in roughly circular orbits some 1,100 km high by Atlas F and H launch vehicles between 1976 and 1987.
