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

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

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

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]
