NOAA-7 was launched in June 1981 and was a third generation
operational meteorological satellite for use in the National
Operational Environmental Satellite System (NOESS) and for the support
of the ... Global Atmospheric Research Program (GARP) during 1978-84. The
satellite design provided an economical and stable sun-synchronous
platform for advanced operational instruments to measure the earth's
atmosphere, its surface and cloud cover, and the near-space
environment. The satellite was based upon the Block 5D spacecraft bus
developed for the U.S. Air Force, and it was capable of maintaining an
earth-pointing accuracy of better than plus or minus 0.1 degree with a
motion rate of less than 0.035 degree/second.
Primary sensors included an Advanced Very High Resolution Radiometer
(AVHRR) and a TIROS Operational Vertical Sounder (TOVS). Secondary
experiments consisted of a Space Environment Monitor (SEM) and a Data
Collection and Platform Location System (DCPLS). A contamination
monitor was provided by the U.S. Air Force to assess contamination
sources, levels, and effects for consideration on future spacecraft.
