Himawari-8 Spacecraft Overview


The figure below shows the sketch of Himawari-8. It carries a new unit called the Advanced Himawari Imager (AHI). The table below lists the major specifications of Himawari-8.

New frequency bands are introduced for communication between the satellites and ground stations. The Ka-band is used for downlinking of meteorological data, and the Ku-band is used for telemetry and command operations. The satellite each carries a transponder to relay environmental data from data collection platforms (DCPs) to sustain the data collection system (DCS).
