USA-100, also known as GPS IIA-15, GPS II-24 and GPS SVN-36, is an American navigation satellite which forms part of the Global Positioning System. It was the fifteenth of nineteen Block IIA GPS satellites to be launched.
USA-100 was launched at 03:40:01 UTC on 10 March 1994, atop a Delta II carrier rocket, flight number D226, flying in the 7925-9.5 configuration. The launch took place from Launch Complex 17A at the Cape Canaveral Air Force Station, and placed USA-100 into a transfer orbit. The satellite raised itself into medium Earth orbit using a Star-37XFP apogee motor.
On 15 April 1994, USA-100 was in an orbit with a perigee of 19,986 kilometres (12,419 mi), an apogee of 20,315 kilometres (12,623 mi), a period of 716.69 minutes, and 54.9 degrees of inclination to the equator. It broadcasts the PRN 06 signal, and operates in slot 1 of plane C of the GPS constellation. The satellite has a mass of 1,816 kilograms (4,004 lb). It had a design life of 7.5 years, but it remained in service until February 2014, shortly after the launch of USA-248.
