一种卫星遥测信息聚合处理方法
By functionally dividing and systematically processing on-board telemetry information, a comprehensive telemetry package for the entire satellite is generated. This solves the problems of insufficient telemetry information integration and limited downlink transmission, enabling rapid transmission in low-rate channels and rapid fault location in abnormal situations, thereby improving the integration and security of satellite telemetry.

AI Technical Summary
In existing technologies, the integration of telemetry information among various subsystems or individual units on the satellite is not high, the telemetry utilization rate is low, the downlink of telemetry data is limited, it is difficult to quickly transmit and identify the critical status of the entire satellite within limited telemetry and control resources, and it is impossible to quickly locate and handle problems in abnormal situations.
Telemetry information from various subsystems or individual units on the satellite is categorized by similar functional types and processed systematically using algorithms to generate status telemetry data. This data is then aggregated into a comprehensive satellite-wide telemetry package. The telemetry display and downlink strategy is adjusted to adapt to different rate channels, especially to quickly transmit the satellite's status information in low-rate channels. In abnormal situations, the display strategy is adjusted to quickly locate faults.
It improves the integration and transmission efficiency of telemetry information, reduces channel resource consumption, ensures the complete and rapid transmission of satellite status information under low-rate channels, enhances the ground's ability to quickly interpret and locate integrated telemetry data packets, and ensures the safe operation of the satellite.
