USA-192

USA-192, also known as GPS IIR-16(M), GPS IIRM-3 and GPS SVN-58, is an American navigation satellite which forms part of the Global Positioning System. It was the third of eight Block IIRM satellites to be launched, and the sixteenth of twenty one Block IIR satellites overall. It was built by Lockheed Martin, using the AS-4000 satellite bus.

USA-192 was launched at 19:12:00 UTC on 17 November 2006, atop a Delta II carrier rocket, flight number D321, flying in the 7925-9.5 configuration. The launch took place from Space Launch Complex 17A at the Cape Canaveral Air Force Station, and placed USA-192 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37FM apogee motor.

By 17 January 2007, USA-192 was in an orbit with a perigee of 20087 km, an apogee of 20277 km, a period of 717.96 minutes, and 55 degrees of inclination to the equator. It is used to broadcast the PRN 12 signal, and operates in slot 4 of plane B of the GPS constellation. The satellite has a mass of 2032 kg, and a design life of 10 years. As of 2012 it remains in service.
