USA-293, also known as GPS-III SV02 or Magellan, is a United States navigation satellite which forms part of the Global Positioning System. It was the second GPS Block III satellite to be launched.

Satellite

[edit]

SV02 is the second GPS Block III satellite to be launched. Ordered in 2008, technical delays to the first satellite in the program, SV01, pushed launch back to 2019.[1]

The spacecraft is built on the Lockheed Martin A2100 satellite bus, and weighs 3,680 kg (8,110 lb).[2]

Launch

[edit]

USA-293 was launched by United Launch Alliance on 22 August 2019 at 13:06 UTC atop a Delta IV Medium.[3] The launch was the final flight of the single-core Delta IV.[4] The launch took place from Cape Canaveral Space Launch Complex 37, and deployed USA-293 directly into a semi-synchronous orbit.[4]

Orbit

[edit]

As of 2021, USA-293 was in a 55.4 degree inclination orbit with a perigee of 20,157 kilometres (12,525 mi) and an apogee of 20,221 kilometres (12,565 mi).[5]
