Template:Infobox spaceflight USA-80, also known as GPS IIA-4, GPS II-13 and GPS SVN-28, was an American navigation satellite which formed part of the Global Positioning System. It was the fourth of nineteen Block IIA GPS satellites to be launched.
USA-80 was launched at 03:20:00 UTC on 10 April 1992, atop a Delta II carrier rocket, flight number D208, flying in the 7925-9.5 configuration. The launch took place from Launch Complex 17B at the Cape Canaveral Air Force Station, and placed USA-80 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37XFP apogee motor.
On 12 May 1992, USA-80 was in an orbit with a perigee of 19,979 kilometres (Template:Convert/round mi), an apogee of 20,384 kilometres (Template:Convert/round mi), a period of 717.94 minutes, and 55.1 degrees of inclination to the equator. It had PRN 28, and operated in slot 2 of plane C of the GPS constellation. The satellite had a mass of 1,816 kilograms (Template:Convert/round lb). It had a design life of 7.5 years; however, it was retired early, on 15 August 1997. It was replaced by USA-117.
