GOSAT is a Japanese environment-monitoring satellite


GOSAT (Greenhouse gases Observing SATellite) is an environment-monitoring satellite developed by Japan which launched on 23 January 2009 and remains operational.
It is part of ESA's Third Party Missions Programme, in which ESA has an agreement with JAXA to distribute data products from the mission.

Non-scientific measuring instruments

A total of 8 CAMs are being accommodated at strategic locations on GOSAT with the objective to monitor the spacecraft exterior in orbit.

(Technical Data Acquisition Equipment): TEDA is onboard space environment measurement system with the objective to monitor the orbital radiation environment.
