Other Designations: Geostationary Meteorological Satellite. Code Name: Himawari. Class: Earth. Type: Weather. Nation: Japan. Agency: Japan(Himawari 2).

The Geostationary Meteorological Satellite series were spin-stabilized satellites. They were 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. Launching organization: National Space Development Agency of Japan (NASDA). Function: 1) Observation of meteorological phenomena by the visible and infra-red spin scan radiometer. 2) Collection of weather data from various stations. 3) Distribution of weather data to earth stations. 4) Monitoring of solar particles.


Specification

Total Mass: 746 kg.
