USA-265, also known as GPS IIF-11, GPS SVN-73 and NAVSTAR 75, is an American navigation satellite which forms part of the Global Positioning System. It was the eleventh of twelve Block IIF satellites to be launched.[2]

Launch

Built by Boeing and launched by United Launch Alliance, USA-265 was launched at 16:13 UTC on 31 October 2015, atop an Atlas V 401 carrier rocket, vehicle number AV-060.[3] The launch took place from Space Launch Complex 41 at the Cape Canaveral Air Force Station,[5] and placed USA-265 directly into semi-synchronous orbit.[4]

Orbit

As of 5 December 2015, USA-265 was in an orbit with a perigee of 20,444 kilometers (12,703 mi), an apogee of 20,491 kilometers (12,733 mi), a period of 729.58 minutes, and 54.99 degrees of inclination to the equator.[4] It is used to broadcast the PRN 10 signal, and operates in slot 6 of plane E 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 December 9, 2015.[6]
