The combination of satellite application equipment is the multiplier for improving operational capabilities. Traditionally, only the number of satellite application equipment is increased according to the operational needs, rather than optimizing the combination of satellite application equipment, which may cause repetitive configuration of satellite application equipment.This paper puts forward an optimizing algorithm for satellite application equipment combination to address operational needs.To achieve the purpose of avoiding the waste of resources, the combination of satellite application equipment is processed and optimized, its operational effectiveness is evaluated, and whether it is optimal is determined. Through a case analysis, the combination-optimizing algorithm of satellite application equipment is verified, and the optimal combination scheme of satellite application equipment is constructed.
