USA-258, also known as GPS IIF-8, GPS SVN-69 and NAVSTAR 72, is an American navigation satellite which forms part of the Global Positioning System. It was the eighth of twelve Block IIF satellites to be launched.[2]



Launch[edit]


Built by Boeing and launched by United Launch Alliance, USA-258 was launched at 17:21 UTC on 29 October 2014, atop a Atlas V 401 carrier rocket, vehicle number AV-050.[3] The launch took place from Space Launch Complex 41 at the Cape Canaveral Air Force Station,[5] and placed USA-258 directly into medium Earth orbit.[4]



Orbit[edit]


As of 29 October 2014, USA-258 was in an orbit with a perigee of 20,455 kilometers (12,710 mi), an apogee of 20,480 kilometers (12,730 mi), a period of 729.56 minutes, and 55.00 degrees of inclination to the equator.[4] It is used to broadcast the PRN 03 signal, and operates in slot 1 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 12, 2014.[6]
