USA-248, also known as GPS IIF-5, GPS SVN-64 and NAVSTAR 69, is an American navigation satellite which forms part of the Global Positioning System. It was the fifth of twelve Block IIF satellites to be launched.

Launch

Built by Boeing and launched by United Launch Alliance, USA-248 was launched at 01:59 UTC on 21 February 2014, atop a Delta IV carrier rocket, flight number D365, flying in the Medium+(4,2) configuration. The launch took place from Space Launch Complex 37B at the Cape Canaveral Air Force Station, and placed USA-248 directly into medium Earth orbit.

Orbit

As of 22 April 2014, USA-248 was in an orbit with a perigee of 20,175 kilometers (12,536 mi), an apogee of 20,191 kilometers (12,546 mi), a period of 717.99 minutes, and 54.96 degrees of inclination to the equator. It is used to broadcast the PRN 30 signal, and operates in slot 6 of plane A of the GPS constellation. The satellite has a design life of 15 years and a mass of 1,630 kilograms (3,590 lb). It is currently in service following commissioning on May 30, 2014.
