GMS 1

NSSDCA/COSPAR ID: 1977-065A

Description

The Geostationary Meteorological Satellite (GMS) was Japan's contribution to the international GARP (Global Atmospheric Research Program). One major objective of GARP was to obtain synoptic global meteorological data sets for 1 year's duration (to include two optimized observing periods of a few weeks each). These data served as raw material to optimize computer models for meteorological prediction. It was hoped that determination could be made of the time limitation for short-term modeling. This spacecraft was roughly cylindrical with a height of 345 cm and a diameter of 216 cm. The cylindrical surface was covered with solar cells which could provide 225 W. The satellite was spin-stabilized with a despun earth-pointing antenna. The satellite was positioned near 140 deg E. Designed to operate for 5 years, the satellite was turned off in 1981 after 4 1/2 years in orbit.
