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. [3] The launch took place from Space Launch Complex 37B at the Cape Canaveral Air Force Station, [5] and placed USA-248 directly into medium Earth orbit. [4]

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. [4] 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). [2] It is currently in service following commissioning on May 30, 2014. [6]
