Embodiment Construction

[0062] The steps of an agile satellite single-satellite task planning method based on a moving target according to the present invention are as follows: firstly, calculate the visible time window according to the model characteristics and constraints of the satellite and the observed target, and form an initial task sequence; secondly, construct the objective function and In the genetic algorithm model, the conflict elimination operator is introduced to calculate the conflict sequence; again, the task sequence is optimized and solved to obtain a conflict-free task sequence that meets the constraints; finally, the satellite task observation plan is calculated and the satellite maneuver angle is calculated. The invention can improve the efficiency of satellite earth observation, rationally utilize limited satellite resources, and complete the task of capturing and observing moving targets.

[0063] The first step is to calculate the visible time window according to the model char...
