MTSAT are a series of weather and aviation control satellites. They are geostationary satellites. They are owned and operated by the Japanese Ministry of Transport and the Japan Meteorological Agency (JMA), and provide coverage for the hemisphere centred on 140° East; this includes Japan and Australia who are the principal users of the satellite imagery that MTSAT provides. They replace the GMS-5 satellite. They can provide imagery in five wavelength bands - visible and four infra-red, including the water vapour channel. The visible light camera has a resolution of 1 km; the infra-red cameras have 4 km (resolution is lower away from the equator at 140° East. They spacecraft have a planned lifespan of five years. MTSAT-1 and 1R were built by Space Systems/Loral. MTSAT-2 was built by Mitsubishi

The launch of MTSAT-1 failed on 15 November 1999 and the spacecraft was destroyed. MTSAT-1R was sucessfully launched on 26 February 2005 and became fully operational on 28 June 2005. As of August 2005 MTSAT-2 was not scheduled for launch. If MTSAT-2 is launched sucessfully it will be put into hibernation until the end of MTSAT-1R's life.
