description	The invention provides a method and a system for acquiring a ground multi-target access window by a satellite. The method comprises the following steps: a target position conversion step: converting a target geographic latitude and longitude into an earth-fixed system position; a distance vector component calculation step of an earth-fixed coordinate: calculating a component of a distance vector between the satellite and the target point in the earth-fixed coordinate system; a load coordinate distance vector component calculation step: calculating the component of the distance vector between the satellite and the target point under the load coordinate system; and a target access window calculation step: calculating the target access window of the satellite. The invention provides a method for acquiring a ground multi-target access window by a satellite, and solves the calculation problem of the ground multi-target access window by the satellite. The invention provides a method for simulating a ground multi-ta
