Radio and optical remote sensing - Satellite and ground observations. III - An experiment of MOS-1 verification (application of ground-based laser beacon to earth image calibration)
Abstract
The spot image of a ground-based laser beacon is very useful for calibration/correlation of earth's surface images taken by cameras and optical radiometers, because it corresponds to an infinitively small landmark whose absolute location and brightness are known precisely. Here, results are reported from experiments of tracking the MOS-1 and transmitting a laser beam from a ground station to the satellite. An argon ion laser is used as a beacon, and images taken by the MESSR are analyzed. Geometric errors were found in the MESSR earth images, and the satellite's attitude was examined by comparing the position of the laser spot image and the scene center.
