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.
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. The launch took place from Space Launch Complex 41 at the Cape Canaveral Air Force Station, and placed USA-265 directly into semi-synchronous 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. 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).  It is currently in service following commissioning on December 9, 2015.
