- The Geostationary Meteorological Satellite series are spin-stabilized satellites. They have been developed to contribute to the improvement of Japan's meteorological services and the development of weather satellite technology. The satellites consist of a despun section which holds the earth-oriented antennas and a 100-rpm rotating spin section which contains the Visible and Infrared Spin Scan Radiometer (VISSR), electronic devices, etc. They have been used for the World Meteorological Organization's world Weather Watch Program which is sustained by five geostationary satellites. The first satellite in the series was launched by a U.S. Delta rocket in July 1977. The GMS-2,3 were launched by Japanese N-II rockets in August 1981 and 1984, and the GMS-4 was launched by Japanese H-I rocket in September. The following is a summary of the GMS series.
