USA-213, also known as GPS SVN-62, GPS IIF SV-1 and NAVSTAR 65, is the first satellite in the Block IIF series of Global Positioning System navigation satellites. It will be used to relay signals for the United States Air Force Navstar Global Positioning System (GPS). The satellite was launched at 03:00 UTC on 28 May 2010. It will be placed into plane B of the GPS constellation, and will transmit the PRN-25 signal. PRN-25 was previously broadcast by USA-79, which was retired in late 2009 after almost eighteen years of service.
USA-213 is a 1,630-kilogram (3,590 lb) spacecraft, which is expected to remain in service for at least twelve years. In addition to broadcasting the same signals as previous satellites, it will also broadcast the L5 signal, and a military signal known as M-code. Its signal accuracy is expected to be twice that of its predecessors. It is the sixty-first GPS satellite to be launched, and the fiftieth Block II spacecraft.
GPS IIF spacecraft are built by Boeing, under a contract which was originally signed in 1996. At the time, thirty three satellites were planned, however this has since decreased to twelve.
GPS IIF SV-1 was launched on a United Launch Alliance Delta IV-M+(4,2) rocket, flying from Space Launch Complex 37B at the Cape Canaveral Air Force Station. This made it the first GPS satellite to be launched on an Evolved Expendable Launch Vehicle, and the first time since 1985 that anything other than a Delta II had been used to launch one.
