GMS (Geosynchronous Meteorological Satellite)
 |
GMS-3
|
A series of weather satellites managed by the Japanese Meteorological Agency
and NASDA (National Space Development Agency);
their indigenous name Himawari means "sunflower." All have been located
in geostationary orbit at 140° E. The first GMS was launched in 1977
and the most recent, GMS-5, on Mar. 18, 1995. GMS-5 is equipped with a VISSR
(Visible and Infrared Spin Scan Radiometer), which scans Earth's surface
line by line, each line consisting of a series of pixels. For each pixel
the radiometer measures the radiative energy at three different wavelengths
bands – one in the visible region and two in the infrared.
