Abstract: Multiple complex constraints,including side-looking power,data capacity,data transmission and so on,are calculated in the imaging scheduling of earth observing satellites(EOS),thus the scheduling is a complicated combinatorial optimization problem.Many previous researches have do some predigestion on them.This paper deals with the united imaging scheduling problem for multiple satellites,which includes several types of satellites,and considers all aforementioned constraints.Then mathematical model is proposed,and an iterative repair method is introduced to solve the multiple earth observing satellites imaging scheduling problem of multiple EOS.Corresponding insertion choice and retraction choice heuristic rules based on distributing of imaging tasks are introduced to guide the search.Experimental results show that the iterative repair method is suitable for EOS imaging scheduling.
