Attitude Scheduling for Dynamic Imaging of Agile Earth Observation Satellite along a Curve Target

Abstract

An attitude scheduling approach is presented for dynamic imaging of agile earth observation satellite (AEOS) along a curve target. First, build a six-order or seven-order polynomial model of target position in the earth-fixed frame and the image time through iterative fitting. Then, based on the obtained model calculate the roll angle and pitch angle for target tracking and the yaw angle for image motion compensation of TDI-CCD camera at each imaging time point. The simulation results demonstrate that the proposed approach is capable of effectively addressing the problem of continuous dynamic imaging along curve targets, such as coastline, borderline, rivers, etc.
