The high-throughput satellite constellation in-orbit real-time monitoring forecasting method according to claim 8, characterized in that, The high-throughput satellite cluster on-orbit real-time monitoring and prediction method comprises the following steps: S1: The ground telemetry control module (100) transmits and receives real-time telemetry and remote control, obtains real-time state information of the satellite, and transmits data to G60 high-throughput satellite cluster on-orbit real-time monitoring and prediction; S2: The on-orbit data real-time transfer module (200) processes satellite data transmitted by the ground telemetry control module (100), on the one hand, distributes satellite data, and on the other hand, screens satellite data and processes it into data and data files using algorithms; S3: The satellite real-time on-orbit operation monitoring module (300) receives data and data files processed by the on-orbit data real-time transfer module (200), and converts the data content into 2D and 3D views, combines input satellite and ground station information, and real-time monitors satellite on-orbit operation position and real-time relative position between satellite and ground station, predicts and predicts satellite passing through the station through the satellite real-time on-orbit operation monitoring module (300), and calculates ephemeris to predict and warn satellite on-orbit collision; S4: The ground comprehensive module (400) receives data of the on-orbit data real-time transfer module (200), performs autonomous diagnosis on the health status of the satellite on-orbit operation through real-time data and historical data, autonomously generates a treatment strategy for a satellite diagnosed as abnormal, and forwards the strategy information to the ground telemetry control module (100) through the on-orbit data real-time transfer module (200).
