Method for maintaining walker constellation formation and terminal device

A terminal device, comprising a non-transitory memory, a processor and a computer program which is stored on the memory and can be run on the processor, wherein the computer program, when executed by the processor, implements a method for maintaining Walker constellation formation, comprising steps of:

• determining, according to parameters of a Walker constellation, a first offset amount of each satellite within a simulation time period;
• performing first offset on each satellite according to the first offset amount 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.
