Geolocation. Visible/Infrared Imager/Radiometer Suite Algorithm Theoretical Basis Document. Version 5, Revision 1

摘要

The Visible Infrared Imaging Radiometer Suite (VIIRS) geolocation algorithm will be implemented as part of the VIIRS raw data processing software in order to include Earth location and related spatial information in the VIIRS data products. Geolocation data fields will be computed for each resolutions ideal band detectors. The Earth location fields, including geodetic latitude, longitude, and height, are computed using rigorous models of the Earth, the NPOESS spacecraft, and the VIIRS instrument. These models account for instrument dynamics including the rotating telescope and half angle mirror, spacecraft position, velocity, and attitude, and the Earths terrain surface.
