Design and Implementation of Satellite Status Processing and Monitoring System Based on Multi-channel High-rate Frame Processing

The stable establishment of space-ground communication channels enables the ground control center to receive telemetry data, tracking and control signals, as well as scientific and observational data from the satellite. Satellite telemetry data serves as an important basis for reflecting the working status of various subsystems and individual equipment on the satellite during its on-orbit operation and is also the basis for judging satellite faults, which are divided into real-time telemetry and delayed telemetry data. Real-time telemetry data are the telemetry data collected in real-time by the satellite, which can truly reflect the working status of the satellite; delayed telemetry data are compressed real-time telemetry data, where the time interval between adjacent sampling points during compression is long. The construction of the satellite status quantity processing monitoring platform aims to process and display the status data from the satellite downlink according to specific protocols through software systems, mainly including satellite data acquisition and processing, real-time monitoring and status analysis, anomaly detection and alarming, and satellite health management. Facing the traditional on-orbit satellite downlink data channels, which include satellite telemetry channel data and data transmission channel data, the telemetry channel data refers to the downlink data of the S-band telemetry channel, while the data transmission channel data refers to the engineering parameters of the data transmission. Considering the characteristics of the data transmission channel data, such as high rate, dual channels, and multiple application modes, a satellite status quantity processing monitoring system has been designed. This system is not only capable of processing multi-channel data but also performs framing processing, parsing, display, querying, storage, and exception alarming for high-speed data transmission engineering parameters. In addition, this software has been successfully applied to the mission operation control system of on-orbit satellites, meeting the real-time monitoring needs for satellite platform models and payloads.
