USA-260, also known as GPS IIF-9, GPS SVN-71 and NAVSTAR 73, is an American Satellite navigation which forms part of the Global Positioning System. It was the ninth of twelve Block IIF satellites to be launched.[2]
Launch
Built by Boeing and launched by United Launch Alliance, USA-260 was launched at 18:36 UTC on 25 March 2015, atop a Delta IV carrier rocket, flight number D370, 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-260 directly into medium Earth orbit.[4]
Orbit
On 25 March 2015, USA-260 was in an orbit with a perigee of 20,445 kilometers (12,704 mi), an apogee of 20,468 kilometers (12,718 mi), a period of 729.14 minutes, and 55.00 degrees of inclination to the equator.[4] It is used to broadcast the PRN 26 signal, and operates in slot 5 of plane B 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 April 20, 2015.[6]
