Research on Autonomous Task Planning for Terrestrial Ecosystem Carbon Inventory Satellite
Remote sensing satellites in low earth orbit(LEO)usually target specific ground-ob-jects worldwide or inside China.In order to improve autonomy of satellite operations in orbit,a method of autonomous task planning for remote sensing satellites based on ground-object proper-ties is proposed.Firstly,the longitude and latitude of the nadir point after 90 minutes is extrapo-lated and forecasted.Then the lighting/shadow,land/ocean and domestic/overseas properties of the forecasted nadir point are obtained using the on-board map and the solar elevation angle.Af-terwards,the time table of every payload is generated based on the smoothed ground-object prop-erties.Autonomous task planning for every payload can be performed about one-revolution in ad-vance.
