Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0020] The present invention provides a method for continuously establishing inter-satellite links supporting the orbit maneuvering of Beidou-3 satellites, which uses post-control theoretical orbits to assist link establishment, so that the inter-satellite links can operate stably and reliably.
[0021] The Beidou-3 GEO satellite needs to perform orbit control due to the position of the geosynchronous belt, or the IGSO and MEO satellites need to perform orbit change operations due to reasons such as maintaining the constellation configuration. The orbit parameters of the satellite will change before and after the orbit maneuver, and the number of The true orbital parameters could not be determined within hours. The almanac originally used for the establishment of the inter-satellite link will not match the real orbit, and the accumulation of ...

The invention discloses an inter-satellite link continuous establishment method supporting orbital maneuver of a Beidou No.3 satellite, which utilizes a post-control theory orbit to assist link establishment so as to enable an inter-satellite link to stably and reliably operate, and comprises the following steps: firstly, planning an inter-satellite link topology route of satellites, and formulating an inter-satellite link establishment plan; then, two groups of almanac parameters of the whole-network satellite are generated before orbital maneuver, the almanac parameters are annotated to the satellite, then almanac link establishment is started immediately, finally orbital maneuver is implemented, and inter-satellite links are kept continuous. The inter-satellite link continuous establishment method is completely based on the satellite design state, the processing flow can be automated, the inter-satellite link of the orbital maneuvering satellite can be improved from K-hour interruption to whole-course continuity without interruption, and a technical guarantee is provided for improving the service availability of a navigation system.
Description
technical field [0001] The invention belongs to the technical field of satellite navigation, and relates to a method for continuously establishing an inter-satellite link supporting Beidou-3 satellite orbit maneuvering. Background technique [0002] The Beidou-3 satellite system is a navigation satellite system independently developed by my country, which has the function of providing navigation, positioning and timing services to users around the world. The Beidou-3 satellite is equipped with an inter-satellite link terminal to realize the measurement and communication functions between the star-satellite and the star-ground. The inter-satellite link is an important way to monitor the status and upload data of the satellites in the entire network of the constellation, and it is the only way to manage overseas satellites in real time. Satellites are affected by orbital perturbation and need to conduct regular orbital maneuvers to maintain the configuration of the navigation...
