NOAA-11
type: Concept
definition: NOAA-11 (ATN series) was launched on September 24, 1988 and is a third-generation operational meteorological satellite for use in the National Operational Environmental Satellite System (NOESS). The satellite design provides 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 is based upon the Block 5D spacecraft bus developed for the U.S. Air Force, and is 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 include (1) an Advanced Very High Resolution Radiometer (AVHRR), (2) TIROS Operational Vertical Sounder (TOVS), and (3) a Solar Backscatter Ultraviolet Spectrometer (SBUV/2). The secondary experiment is a Data Collection System (DCS). A Search and Rescue (SAR) system is also carried on NOAA-11.
