Fast Calculation Method for Target Access Time of Sun Synchronous Orbit Remote Sensing Satellite
Target access calculation refers to the calculation of observation time and attitude of remote sensing satellites towards the target based on the orbit of remote sensing satellites and the position of the target to be observed.It is one important basic technology in remote sensing satellite task control.An efficient target access calculation method can significantly improve the timeliness of satellite task management,which is of great significance for subsequent large-scale remote sensing constellation task management.By utilizing the characteristic of constant local time at the intersection of solar synchronous orbit satellites,a shorter time window for the satellite to pass through the target can be quickly estimated,and then the ephemeris within the time window can be calculated point by point to obtain the optimal time for the satellite to access the target.Experimental results demonstrate that this method can significantly improve compu-tational efficiency of target access time.
