DemoSat 2

DemoSat 2 [Astranis]

The DemoSat 2 is a 3U CubeSat by Astranis to perform an UHF radio test for Astranis planned small GEO communications satellites.

The cubesat serves as a pathfinder for the technology to be used on Astranis' planned small GEO communications satellites. It carries an early prototype of their software-defined UHF radio technology. The mission demonstrated streaming HD videos up to the spacecraft, processed in real-time by the digital payload, and then sent back down again to the ground station in Alaska.

The satellite was launched in January 2018 as a piggy-back payload on an Indian PSLV-XL rocket.
