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.[1]

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.[2] The launch took place from Space Launch Complex 3W at Vandenberg Air Force Base,[3] and placed USA-5 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-27 apogee motor.[1]

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.[4] The satellite had a design life of 5 years and a mass of 758 kilograms (Template:Convert/round lb).[1] 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.
