USA-289, also known asGPS-III SV01 orVespucci, is aUnited Statesnavigation satellite which forms part of theGlobal Positioning System. It was the firstGPS Block III satellite to be launched.[2]

Satellite

[edit]

SV01 is the firstGPS Block III satellite to be launched. Ordered in 2008 and originally intended to be launched in 2014, numerous technical delays pushed launch back to 2018.[3]

The spacecraft is built on theLockheed Martin A2100 satellite bus, and weighs in at 4,400kg (9,700lbs), making SV01 the heaviest GPS satellite ever launched.[4]

Launch

[edit]

USA-289 was launched bySpaceX on 23 December 2018 at 13:51 UTC atop expendableFalcon 9 boosterB1054. The launch took place fromSLC-40 of theCape Canaveral Air Force Station, and placed USA-289 directly intosemi-synchronous orbit.

Orbit

[edit]

As of 2021, USA-289 was in a 55-degreeinclination orbit with aperigee of 20,158 kilometers (12,525 miles) and anapogee of 20,222 kilometers (12,565 miles).[5] The satellite is the first GPS satellite to be able to broadcast the civilianL1C signal.[6]

GPS-III SV01 is launched on a Falcon 9.
