Problems solved by technology

In the current constellation design, due to the small number of satellites in the existing constellation and the large range of satellite drift, the constellation control boundary conditions considered are mainly based on the maximum allowable drift of the satellite’s coverage to the ground, which has a negative effect on the constellation security caused by con...

Abstract

The invention provides an orbit control frequency analysis method and device for Walker constellation configuration maintenance. The method comprises the following steps of calculating the maximum permissible drift distance of a phase under the condition of the maximum permissible drift distance of the right ascension of different ascending nodes, determining an ascending node right ascension maximum allowable drift amount, a phase maximum allowable drift amount, a relative ascending node right ascension average drift rate and a relative phase average drift rate, according to the ascending node right ascension maximum allowable drift distance, the phase maximum allowable drift distance, the relative ascending node right ascension average drift rate and the relative phase average drift rate, calculating the orbit control frequency of the constellation satellite in the life cycle under the absolute configuration maintaining method, and taking the maximum allowable attenuation height as a constraint, and calculating the orbit control frequency of the constellation satellite in the life cycle under the relative configuration maintenance method. The method is suitable for the configuration maintenance of the low-orbit large-scale Walker constellation.

Description

technical field [0001] The invention relates to the technical field of Walker constellation configuration maintenance, in particular to an orbit control frequency analysis method and device for Walker constellation configuration maintenance. Background technique [0002] The low-orbit large-scale Walker constellation is a satellite constellation composed of more than hundreds of satellites with an orbital altitude of less than 2,000 kilometers. The low-orbit large-scale Walker constellation can provide users with low-latency, high-speed Internet broadband access worldwide, and has huge economic benefits and military application potential. It has attracted the attention of various countries and achieved rapid development. At present, the low-orbit large-scale Walker constellations under construction include the Starlink constellation in the United States and the OneWeb constellation in the United Kingdom, and many countries are in the design planning, including: China's State...
