Global Change Observation Mission
Programme details
Programme description
The Global Change Observation Mission (GCOM) is a follow-on to ADEOS-2, consisting of 2 satellites: GCOM-W for water circulation changes, and GCOM-C for climate changes.
GCOM-W addresses multi-purpose MW imagery for ocean, land and precipitation.
GCOM-C addresses ocean colour, vegetation and aerosol
Japanese programme: JAXA responsible of development and operations.
The platforms are actively stabilised over 3 axes.
The design life time is 5 years.
The satellites exploit sun-synchronous orbits around 13:30, coordinated with that of POES satellites, Suomi-NPP and JPSS.
See detailed descriptions at http://www.jaxa.jp/projects/sat/gcom_w/index_e.html and http://www.jaxa.jp/projects/sat/gcom_c/index_e.html .
Data circulation
Global data stored onboard and downlinked to the Svalbard station, then transferred to the Tsukuba Space Center (TKSC).
Real-time transmission to a JAXA domestic station in Katsuura (with backup in Tsukuba) for further relay to the TKSC. Also direct-read-out to specifically appointed stations.
Processing and distribution from TKSC.
