Table of ContentsThe Geostationary Operational Environmental Satellites (GOES) provide a wide variety of meteorological satellite services as a part of the network of satellites for the World Weather Watch program planned by the World Meteorological Organization (WMO). The GOES 4 and GOES 5 satellites operating from the two geostationary orbit locations of 75°W and 135°W longitude use newer technology and have expanded capability relative to their predecessors, SMS I and 2 and GOES 1, 2 and 3. The satellite directly transmits day and night observations of global scale weather, hurricanes and other more localized severe storms to an earth-based processing center, then in a time-shared fashion relays the processed, high resolution observation data along with weather facsimile (WEFAX) data to field stations. Weather observations are generated in the Visible and Infrared Spin Scan Radiometer, VISSR, Atmospheric Sounder (VAS). The VAS performs operational visible and infrared imaging as well as experimental multi-spectral imaging (MSI) and temperature sounding of the atmosphere by programing the 12 IR spectral bands. The satellite provides direct interrogation and simultaneous relay transmission between the command data acquisition station (CDAS) and multiple, widely dispersed data collection platforms (DCP). The satellites also monitor the condition of the earth’s magnetic field and energetic particle flux in the vicinity of the spacecraft and observe x-ray emissions from the sun. These measurements are made through instruments collectively called the Space Environmental Monitor (SEM) and are transmitted directly to a central processing center. The satellite performs all these communications functions by means of a multi-function communications system which operates on S-Band and UHF frequencies at bit rates varying from 100 bps to 28 Mbps.
