USA-289, also known as GPS-III SV01 or Vespucci, is an United States navigation satellite which forms part of the Global Positioning System. It was the first GPS Block III satellite to be launched.
USA-289 was launched by SpaceX on 23 December 2018 at 13:51 UTC atop expendable Falcon 9 booster B1054. The launch took place from SLC-40 of the Cape Canaveral Air Force Station, and placed USA-289 directly into semi-synchronous orbit.
As of 2021, USA-289 was in a 55-degree inclination orbit with a perigee of 20,158 kilometers (12,525 miles) and an apogee of 20,222 kilometers (12,565 miles). The satellite is the first GPS satellite to be able to broadcast the civilian L1C signal.
