Launch

Built by Boeing and launched by United Launch Alliance (ULA), USA-266 was launched at 13:38 UTC on 5 February 2016, atop an Atlas V 401 launch vehicle, vehicle number AV-057. [3] The launch took place from Space Launch Complex 41 at the Cape Canaveral Air Force Station, [4] and placed USA-266 directly into semi-synchronous orbit. [5]

Orbit

As of March 2016, USA-266 was in an orbit with a perigee of 20,181 km (12,540 mi), an apogee of 20,196 km (12,549 mi), a period of 717.9 minutes, and 55.01° of inclination to the equator. [5] It is used to broadcast the PRN 32 signal, and operates in slot 5 of plane F of the GPS constellation. [6] The satellite has a design life of 12 years and a mass of 1,630 kg (3,590 lb). [2] It is currently in service following commissioning on 9 March 2016. [7]
