USA-92
Lua error in Module:Infobox at line 199: malformed pattern (missing ']'). USA-92, also known as GPS IIA-12, GPS II-21, GPS SVN-39, and NAVSTAR 39, is an American navigation satellite which forms part of the Global Positioning System. It was the twelfth of nineteen Block IIA GPS satellites to be launched.
USA-92 was launched at 13:27:00 UTC on 26 June 1993, atop a Delta II carrier rocket, flight number D221, flying in the 7925-9.5 configuration.[3] The launch took place from Launch Complex 17A at the Cape Canaveral Air Force Station,[5] and placed USA-92 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37XFP apogee motor.[2]
On 27 July 1993, USA-92 was in an orbit with a perigee of 20,120 kilometres (12,500 mi), an apogee of 20,244 kilometres (12,579 mi), a period of 717.96 minutes, and 54.7 degrees of inclination to the equator.[4] It broadcasts the PRN 09 signal, and operates in slot 1 of plane A of the GPS constellation.[6] The satellite has a mass of 1,816 kilograms (4,004 lb). It had a design life of 7.5 years;[2] however, it was kept in service for over 20 years before finally decommissioned from service on May 19, 2014.[7]
Following decommissioning, it was subsequently placed in a disposal orbit approximately 1000km above the operational constellation on September 21, 2015.[8]
