1. A method for maintaining Walker constellation formation, comprising:
determining, according to parameters of a Walker constellation, a first offset amount of each satellite within a simulation time period;
performing, according to the first offset amount, first offset on each satellite to obtain a Walker constellation after the first offset;
determining, according to parameters of the Walker constellation after the first offset, a second offset amount of each satellite within the simulation time period; and
superimposing the first offset amount and the second offset amount, and performing second offset on each satellite according to a superimposing result so as to maintain the formation of the Walker constellation.
