Embodiment Construction
[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0039] Aiming at the problem that the abnormality of the thruster ignition of the satellite in orbit cannot be found in real time, this embodiment provides a real-time discovery method for the abnormality of the 10N thruster of the satellite in orbit on a certain platform during the position holding ignition period. The method utilizes the historical telemetry of the satellite in orbit The temperature relative difference model is established based on the data, and the real-time, automatic and precise monitoring of the thruster ignition process can be realized through the driving and discrimination of the satellite real-time telemetry data.
[0040] This method is suitable for the on-orbit satellites whose propulsion system adopts a dual-component unified propulsion system. The paired thrusters are ignited during the position keeping process, an...
