Navigation body cross-domain track correction method and storage medium

The invention provides a navigation body cross-domain track correction method and a storage medium, a plurality of collinear water surface guide points are arranged on the water surface, underwater guide points in one-to-one correspondence with the water surface guide points are arranged underwater, and firstly, based on the water surface guide points and actual water surface track points, a water surface track correction algorithm is used for correcting the water surface track of a navigation body; and after the navigation body dives, correcting the diving track of the navigation body by using a diving track correction algorithm based on the underwater guide point and the underwater actual track point. According to the method, the problem of accurately keeping the track of the navigation body in a three-dimensional space is decomposed into the problem of accurately keeping the track in a water surface and underwater single two-dimensional plane, and the problem is solved in sections, so that the navigation b
