NOAA-7 (prior to launch, NOAA-C ) was a Tiros-N series weather satellite that orbited Earth at an altitude of 830 km in a polar orbit . From its launch on June 23, 1981 on an Atlas F rocket to its failure on February 1, 1985, the satellite recorded meteorological data for the National Oceanic and Atmospheric Administration .
The satellite had three-axis stabilization and was based on the 5D version of the DMSP weather satellite developed for the US military .
NOAA-7 carried the following instruments as a payload:
- AVHRR ( advanced very high resolution radiometer ): a high-resolution radiometer for mapping the water surface temperature and for day / night overview images,
- TOVS ( TIROS operational vertical sounder ) consisting of:
- HIRS / 2 ( High Resolution Infrared Radiation Sounder Version 2 ): a device for determining temperature and humidity profiles in the troposphere ,
- SSU ( Stratospheric Sounding Unit ): a four-channel spectrometer in the 60 GHz range for determining temperature profiles of the stratosphere
- MSU ( Microwave Sounding Unit ): a microwave sounding instrument (see microwave radiometer )
- SEM ( space environment monitor ): a radiation measuring device for local electrons and protons .
