GMS 5 was a Japanese geostationary meteorological spacecraft. It replaced GMS 4 (1989-070A) and was initially parked at 140 E longitude. It carried visible and infrared spin-scan radiometers that provided global pictures every 25 minutes at a resolution of 1.25 km (visible) and 5.0 km (infrared). It also had an infrared channel to monitor water vapor content in the atmosphere. Other instruments on board were for search-and-rescue relays and for relaying weather data from ground/sea-based monitoring platforms. The spacecraft had a stabilized earth pointing platform and a 100 rpm spinning section. The spacecraft had a diameter of 215 cm and a height of 354 cm.
