FedSat (Australia's 'Federation Satellite'; sometimes FedSat 1) was an Australian scientific research satellite launched from Tanegashima Space Center, Japan by a NASDA H-IIA launch vehicle  on 14 December 2002 (NASDA is now merged with JAXA). The satellite was developed by the Cooperative Research Centre for Satellite Systems, a cooperative made up of several universities, commercial organisations and government bodies. The ground station is at the Institute for Telecommunications Research, part of the University of South Australia, near Adelaide. Since 2005 it was operated by the Australian Department of Defence.
The satellite had six payloads, as given below:
The satellite platform, comprising the structural/thermal components, power system, attitude control system, onboard computer and groundlink, was originally developed in the UK by Space Innovations Limited. It was later completed along with integration of payloads in Canberra, Australia.
The spacecraft's battery failed in May 2007 and the mission has been terminated, after lasting 18 months longer than expected.
