Abstract: The main topic of this paper are determination method of the attitude parameters of a geostationary meteorological satellite spin axis and gamma correction parameter of satellite image shifting in direction of east-west by means of landmark measurement. A mathematical equation of the attitude and the gamma determination, including the actual algorithms, is presented. In addition, some other cases of impact image location accuracy are described. Finally, a set of actual results and an error anlysis are presented.

Key words: meteorology satellite, landmark navigation, gamma correction, attitude deter mination
