Research on Digitization Methods for Full-cycle Satellite Telemetry Channel Design

Telemetry wave channel is an important content of the top-level design of satellite telemetry format, and the reasonableness of its design determines the utilization rate of satellite telemetry capacity, which will also directly affect the effectiveness of on-orbit satellite state monitoring. The traditional satellite telemetry channel design suffers from the problems of time-consuming and iterative design, etc. Meanwhile, the repetitive design workload is large, which also easily leads to the mentality fatigue, thus increasing the risk of design errors. In order to solve the above problems, this paper digitizes the design constraints of telemetry channels, and adopts a digital design method based on model system engineering to realize a design method that takes into account the overall design efficiency and design rules, and verifies the feasibility and effectiveness of the method from three aspects including design time-consuming, design time consumption, and first design compliance rate as well.
