SV01 is the first GPS 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 the Lockheed Martin A2100 satellite bus, and weighs in at 4,400kg (9,700lbs), making SV01 the heaviest GPS satellite ever launched.[4]
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).[5] The satellite is the first GPS satellite to be able to broadcast the civilian L1C signal.[6]
