What is Naval Ocean Surveillance System mean?

The Naval Ocean Surveillance System (NOSS) is a series of signals intelligence satellites that have conducted electronic signals intelligence for the U.S. Navy since the early 1970s. The first series of satellites were codenamed "White Cloud" or "PARCAE", while second and third-generation satellites have used the codenames "Ranger" and "Intruder".
