Integrated control method and device for low-orbit satellite communication and orbit maintenance

The invention provides an integrated control method and device for communication and orbit maintenance of a low-orbit satellite, and relates to the technical field of satellite communication.According to the method, the target orbit of the low-orbit satellite is determined according to the current orbit of the low-orbit satellite, the position coordinates of a user target and the data receiving and transmitting coverage range of the user target, the user target is located in the center of the sub-satellite point trajectory network when the low-orbit satellite is in the target orbit, and the distance between the boundary of the sub-satellite point trajectory network and the user target is smaller than the first threshold value, so that the service guarantee time period of the low-orbit satellite to the user target is longest, the communication frequency is maximum, and the user experience is improved. According to the method, a single low-orbit satellite is utilized to realize normalized communication guarante
