Scan mirror motion compensation technology for high accuracy satellite remote sensor

摘要

To acquire high quality image, the control system of the new generation Geostationary Meteorological Satellite in China (GMSC) must have high pointing precision and degree of attitude stability, besides image navigation and registration (INR) must be proceeded. This paper studies scan mirror motion compensation in image registration by using model predictor method. In the study of model predictor method, the total technical case of scan mirror motion compensation is designed; the analysis of the scan mirror motion disturbances is proceeded; and the compensated objects are ensured through analysis of simulation; the model predictor mathematical model in scan mirror motion compensation model is founded; the model predictor method compensated arithmetic is designed; the valid arithmetic of model predictor method is proved through simulation. The research provides theoretical principles and practicable references to develop the new generation GMSC.
