Template:Infobox spaceflight USA-5, also known as Navstar 10, GPS I-10 and GPS SVN-10, was an American navigation satellite launched in 1984 as part of the Global Positioning System development programme. It was the tenth of eleven Block I GPS satellites to be launched.
USA-5 was launched at 21:41 UTC on 8 September 1984, atop an Atlas E/F carrier rocket with an SGS-2 upper stage. The Atlas used had the serial number 14E, and was originally built as an Atlas E. The launch took place from Space Launch Complex 3W at Vandenberg Air Force Base, and placed USA-5 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-27 apogee motor.
By 8 October 1984, USA-5 had been raised to an orbit with a perigee of 19,961 kilometres (Template:Convert/round mi), an apogee of 20,404 kilometres (Template:Convert/round mi), a period of 717.98 minutes, and 63.2 degrees of inclination to the equator. The satellite had a design life of 5 years and a mass of 758 kilograms (Template:Convert/round lb). It broadcast the PRN 12 signal in the GPS demonstration constellation, and was retired from service on 26 March 1996. It was the last Block I satellite to be decommissioned.
