| - NOAA-9 (ATN series) was launched on December 12, 1984 and was a
third-generation operational meteorological satellite. The satellite
design provided an economical and stable sun-synchronous platform.
This platform enables the satellite to carry 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 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 (1) an Advanced Very High Resolution
Radiometer (AVHRR), (2) a TIROS Operational Vertical Sounder (TOVS),
(3) an Earth Radiation Budget Experiment (ERBE), and (4) a Solar
Backscatter Ultraviolet Radiometer (SBUV/2). The secondary experiment
was a Data Collection and Platform Location System (DCPLS). A Search
and Rescue Satellite Aided Tracking (SARSAT) system was also carried
on NOAA-9.
