It aims to study the technology of optical, mechanical, thermal, control and other disciplines in the integrated simulation of space optical remote sensor and consider the influence of various disciplines on the optical performance index from the system level. It reviewed the foreign advanced optical remote sensor integrated simulation analysis methods, mainly including the STOP subject software data interaction method with JWST as representative and the DOCS state space method with NGST as representative. Integrated approach and modeling procedures of these methods were discussed in details. The implementation of the integrated simulation technology could reduce the period for phased demonstration of conceptual product design and plan, and provided a reliable basis for the development of the overall index. Integrated simulation is the premise of the multi discipline optimization of space optical remote sensor, and the deep integration and the subsystem collaboration simulation will be the development tendency in future.
