Abstract: Focusing on the new requirements of safety and controllability of space telemetry, track and command (TT&C) system in China, a flexible, convenient, independent and controllabe new generation space instrumcntation ship TT&C simulation system based on domestic hardware and software platform is designed and developed by using component and service bus technology on the basis of full demonstration and research. Firstly, the system funcational requirements are described. Secondly, a reconfigurable system architecture is proposed. Thirdly, the key technology of service bus achievement and the design of ship-borne TT&C equipment measurement data simulation model are discussed. Finally, the application validation is carried out. The application results show that the system is reasonable in design, flexible and versatile, and can meet the requirements of comprehensive verification of new generation space instrumentation ship TT&C system.
