Orbit control frequency analysis method and device for Walker constellation configuration maintenance

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 calcula
