It was the third 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-145 was launched at 12:51:01 UTC on 7 October 1999, atop a Delta II carrier rocket, flight number D275, 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-145 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37FM apogee motor.By 10 November 1999, USA-145 was in an orbit with a perigee of 20,096 kilometres (12,487 mi), an apogee of 20,267 kilometres (12,593 mi), a period of 717.96 minutes, and 53 degrees of inclination to the equator. It is used to broadcast the PRN 11 signal, and operated in slot 2 of plane D of the GPS constellation; however, it had been moved to slot 5 by 2011, with USA-71 covering slot 2. 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.GPS IIR-3 was originally intended to use satellite SVN-50; however, it was damaged during launch preparations in May 1999 after rainwater leaked into the cleanroom atop SLC-17A where the satellite was being attached to its rocket. SVN-50 was repaired and launched as GPS IIR-21, becoming the last IIR to fly."@en }
