With the types, functions and structures of spacecraft payloads increasingly complex, the requirements for the performance of integrated simulating and testing system are getting higher and higher. The payload integrated simulating and testing system is an important tool to carry out the payload system-level electrical performance test, the overall integrated test and the launch field test. To meet the sim ulating and testing requirements from different areas and different types of payload and to improve efficiency and adaptability of the system integrated test and verification, a design architecture of spacecraft payloads integrated simulating and testing system with higher reliability, a- daptability and scalability is proposed based on distributed high--performance computer network architecture. The system complies with the design concept of strong cohesion and loose coupling, whose modules can be flexibly reorganized according to the testing requirements, and can he used in all stages of payload research and development with the advantages of high reliability, flexibility, fast reconstruction and extended upgrade. The functions, compositions and specific programs of all testing equipments in the payload integrated simulating and testing system are introduced in detail.
