USA-83, also known as GPS IIA-5, GPS II-14 and GPS SVN-26, is an American navigation satellite which forms part of the Global Positioning System. It was the fifth of nineteen Block IIA GPS satellites to be launched.
USA-83 was launched at 09:20:01 UTC on 7 July 1992, atop a Delta II carrier rocket, flight number D211, flying in the 7925-9.5 configuration.[3] The launch took place from Launch Complex 17B at the Cape Canaveral Air Force Station,[5] and placed USA-83 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37XFP apogee motor.[2]
On 6 August 1992, USA-83 was in an orbit with a perigee of 19,959 kilometres (12,402 mi), an apogee of 20,403 kilometres (12,678 mi), a period of 717.92 minutes, and 55 degrees of inclination to the equator.[4] It has PRN 26, and operates in slot 2 of plane F of the GPS constellation.[6] The satellite has a mass of 1,816 kilograms (4,004 lb). It had a design life of 7.5 years;[2] however, it actually remained in service until January 5, 2015.[7]
It was subsequently disposed of [8]and currently resides in a disposal orbit approximately 1000km above the operational constellation.[9]
