The Geostationary Meteorological Satellite System (GMSS) consists of the MTSAT spacecraft, which captures images and plays various telecommunication roles, and a number of ground facilities that perform a range of functions within the GMSS.

Meteorological Satellite Center (MSC)

The MSC is the central facility of the GMSS. It is home to the computer system that operates and controls MTSAT, processes and analyzes the observed data, produces cloud images and extracts various kinds of meteorological information.

Command and Data Acquisition Station (CDAS)

The CDAS is the gateway for direct communication with MTSAT. At the station, the status of the spacecraft and data reception are tracked, observation data are processed, telemetries are monitored, and commands are sent to MTSAT to operate its onboard equipment. Meteorological data from DCPs are also received at the CDAS and relayed to the MSC. Observed images are disseminated through MTSAT to data utilization stations in Asia and the Western Pacific region.

Data Utilization Stations (MDUSs and SDUSs)

Data utilization stations are facilities that receive and utilize the cloud images relayed through MTSAT.

Data Collection Platform (DCP)

DCP are observing stations installed on isolated islands and ships. DCPs observe weather, ocean wave, earthquake intensity, and tide level and transmit them to the MTSAT.

Emergency-information-receiving Stations

Emergency-information-receiving stations receive earthquake and tsunami information reported by JMA via MTSAT. These stations are operated by local governments throughout Japan.
