Abstract
The resources of ground TT&C (Telemetry, Track and Command) and data transmission station are limited in China, and the visible arc section of satellite is short, which greatly limits the timeliness of satellite on orbit operation control and information return, and affects the full play of satellite efficiency. As a means of response, the relay satellite was born to meet the needs of the full-arc TT&C of key tasks. However, the flexibility of the use of the relay satellite and the number of service objects are still difficult to meet the requirements of ordinary, large number of satellites. Therefore, it is very urgent to realize the real-time telemetry and command of all satellites in the system based on constellation system. In order to meet the requirement of real-time telemetry and command in global network, this paper designs constellation network simulation system, studies the transmission characteristics of ground telemetry and command data and autonomous telemetry and command data in typical constellation configuration, and carries out quantitative simulation analysis. It provides a reference for the optimization of network topology, node cache configuration, routing algorithm and data generation strategy in system design.
