Mission Name: GOES 10The GOES I-M Imager is a multi-spectral, earth scanning instrument capable of providing images of the entire visible half (i.e., full disk) of the Earth or area scans of local regions. This five-channel imaging radiometer is designed to sense radiant and solar reflected energy from selected areas of the earth. It uses a two-axis gimbaled mirror scan system in conjunction with a telescope to allow its multi-spectral channels to simultaneously sweep a 5-mile north to south swath along an east to west, followed by a west to east, path. This enables the Imager to make a full image of the visible portion of the Earth in about 26 minutes.
The Imager is controlled via a defined set of command inputs. The position and size of the areas covered are controlled from the ground.
The Imager consists of electronics, power supply, and sensor modules. The electronics module provides redundant circuitry and performs command, control, and signal processing functions. The sensor module contains the telescope, scan assembly, and detectors and is mounted on the outside of the spacecraft. The power supply module contains converters, fuses, and power control for interfacing with the spacecraft electrical power subsystem. The electronics and power supply modules are mounted on the spacecraft internal equipment panel.
The Imager has five detector arrays which simultaneously acquire radiometric data in five distinct wavelengths or channels. Each channel is used for a specific meteorological objective: Channel 1 covers 0.55 to 0.75 microns (to detect cloud cover); Channel 2 covers 3.80 to 4.00 microns (to detect clouds at night); Channel 3 covers 6.50 to 7.00 microns (to detect water vapor); Channel 4 covers 10.2 to 11.2 microns (to detect surface temperature); Channel 5 covers 11.5 to 12.5 microns (to detect sea surface temperature and water vapor).
Highly accurate determination of the Earth location of the various phenomena measured by the Imager and Sounder is accomplished using a ground computer which processes star and landmark data obtained by the Imager and Sounder.
