Attitude and orbit control semi-physical simulation method and system for satellite constellation

The invention provides an attitude and orbit control semi-physical simulation method and simulation system for a satellite constellation. The satellite constellation comprises a plurality of satellites, each satellite comprises at least one attitude sensor and at least one execution mechanism, and the simulation method comprises the steps that attitude and orbit control dynamics mathematical models corresponding to the satellites are established, and the attitude and orbit control dynamics mathematical models are in one-to-one correspondence with the satellites; an interface module is established, and the interface module is used for obtaining an execution mechanism instruction from each satellite and sending the execution mechanism instruction to the attitude and orbit control dynamics mathematical model corresponding to each satellite; and the attitude and orbit control dynamics mathematical model calculates sensor data and execution mechanism data of the satellites according to the execution mechanism inst
