Big spacecraft has many payloads with complexity constraints and the spacecraft resource-constrained problems.Comprehensive analysis the constraints of the solar altitude angle
the observation mode
the data transmission and the load side of pendulum.Payloads observation constraints are converted to 01 backpack model
combine greedy idea with dynamic programming.Make the fixed observing plan under the same observation needs.Solve regional observation needs and observation conflict with greedy dynamic programming.Experimental results show that the hybrid algorithm is suitable for multiple payloads earth observation mission planning.
