Semi-physical simulation system and simulation method oriented to remote sensing satellite constellation system collaboration

The invention discloses a semi-physical simulation system and simulation method oriented to remote sensing satellite constellation system collaboration. The semi-physical simulation system comprises a physical platform, a digital system, a high-speed hardware interface conversion device and a time synchronization device. The time synchronization device is used for carrying out time calibration on each constituent part of the physical platform and each module of the digital system; the physical platform is used for performing bidirectional data communication with the digital system and receiving target imaging position information sent by the high-speed hardware interface conversion equipment; the digital system obtains an information processing and fusion result; and target imaging position information obtained through load detection simulation is sent to the high-speed hardware interface conversion equipment. According to the semi-physical simulation system, the time consistency of a digital system and a phy
