Ground Station

As part of the Antarctic Broadband program, a satellite telementry and command Earth station has been established at the Australian National University Research School of Astronomy and Astrophysics at Mt. Stromlo, outside Canberra, Australia.

This ground station will be used to support the Antarctic Broadband Demonstrator and Operational Missions and is also available for other small satellite operators to use.

An overview of the capabilities of the ground station is shown below:
