Abstract

The invention discloses an intelligent autonomous operation system of a GEO satellite. The system comprises the steps of: designing a controlling law of orbit keeping and controlling by a neural network based on relative motion equation; estimating the satellite state during orbit keeping and controlling period in real-time by a neural network state observer and taking the satellite state as an autonomous orbit determination result of the orbit keeping and controlling period; and transmitting the estimated state to a controller and realizing the autonomous orbit keeping and controlling of theGEO satellite by the controller, thereby realizing the autonomous operation of the GEO navigation satellite.

Description

technical field [0001] The invention relates to an intelligent autonomous operation system of a GEO satellite, belonging to the technical field of satellite autonomous navigation and control. Background technique [0002] The satellite navigation system can provide navigation, positioning and timing services for the entire earth space with high precision around the clock, and is an extremely important spatial information infrastructure. All major countries in the world are vigorously developing their own satellite navigation systems. China's Beidou satellite navigation system has become the fastest-growing navigation system in the world together with the GPS of the United States, GLONASS of Russia, and GALILEO of the European Union. As a major infrastructure of the country, the Beidou satellite navigation system is an important driving force for the country's industrial transformation. [0003] In the research of the Beidou satellite navigation system, the precise orbit det...
