USA-96, also known as GPS IIA-14, GPS II-23 and GPS SVN-34, was an American navigation satellite which formed part of the Global Positioning System. It was the fourteenth of nineteen Block IIA GPS satellites to be launched.

USA-96 was launched at 17:04:00 UTC on 26 October 1993, atop a Delta II carrier rocket, flight number D223, flying in the 7925-9.5 configuration.[4] The launch took place from Launch Complex 17B at the Cape Canaveral Air Force Station,[6] and placed USA-96 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37XFP apogee motor.[3]

On 25 November 1993, USA-96 was in an orbit with a perigee of 20,104 kilometres (12,492 mi), an apogee of 20,260 kilometres (12,590 mi), a period of 717.96 minutes, and 55 degrees of inclination to the equator.[5] It broadcast the PRN 04 signal, and operated in slot 4 of plane D of the GPS constellation.[7] The satellite has a mass of 1,816 kilograms (4,004 lb). It had a design life of 7.5 years,[3] and lasted until 2 November 2015, being removed from the GPS constellation the next day,[2] almost 22 years later.
