USA-154, also known as GPS IIR-6 and GPS SVN-41, is an American navigation satellite which forms part of the Global Positioning System. It was the sixth Block IIR GPS satellite to be launched, out of thirteen in the original configuration, and twenty one overall. It was built by Lockheed Martin, using the AS-4000 satellite bus.
USA-154 was launched at 17:14:02 UTC on 10 November 2000, atop a Delta II carrier rocket, flight number D281, 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-154 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37FM apogee motor.
By 13 November 2000, USA-154 was in an orbit with a perigee of 20,177 kilometres (12,537 mi), an apogee of 20,498 kilometres (12,737 mi), a period of 724.28 minutes, and 55 degrees of inclination to the equator. It is used to broadcast the PRN 14 signal, and operates in slot 1 of plane F of the GPS constellation. The satellite has a mass of 2,032 kilograms (4,480 lb), and a design life of 10 years. As of 2012 it remains in service.
