Development of automatic method navigation for MVISR imagery of polar-orbital satellite FengYun-1D
Institute of Automation and Control Processes of FEB RAS, Vladivostok, Russia
The development results of automatic navigation method for FY-1D/MVISR images received during full session is presented. The method is based on the orbital motion model SGP4 (with propagation NORAD TLE sets) and a mathematical model of FY-1D/MVISR physical image deformation. Pixel navigation accuracy is achieved on the computation of satellite attitude angles (roll, pitch and yaw) by the ground control points are automatically defined in an image. The misalignment angles between the optical channel sensor axes of the FY-1D/MVISR radiometer is calculated. The behavior relation of the satellite FY-1D/MVISR attitude angles is identified. The approbation results of the new navigation method for a year MVISR data set received in the Center for Regional Satellite Monitoring of Environment of FEB RAS are presented.
