USA 119



This US Navy Ocean Surveillance Satellite (NOSS) was launched from Vandenberg AFB aboard an Atlas E/F rocket. It placed a cluster of one primary satellite and three smaller sub-satellites (that trailed along at distances of several hundred kilometers) into low polar orbit. This satellite array determined the location of radio and radars transmitters, using triangulation, and the identity of naval units, by analysis of the operating frequencies and transmission patterns.
