The invention relates to a navigation efficiency evaluation method and system based on a gravity lighthouse. The method comprises the steps: acquiring a test sea area; arranging reference navigation positioning equipment in the test sea area; determining a reference positioning track of a submarine in the test sea area according to the reference navigation positioning equipment, and obtaining a gravity lighthouse track of the submarine; determining evaluation parameters according to the reference positioning track and the gravity lighthouse track, wherein the evaluation parameters comprise standard deviation, matching rate and similarity; and evaluating the gravity lighthouse navigation system according to the evaluation parameters. According to the navigation efficiency evaluation methodand system based on the gravity lighthouse, the efficiency of the gravity lighthouse navigation system can be evaluated more comprehensively and accurately.
Description
technical field [0001] The invention relates to the field of gravity navigation of underwater vehicles, in particular to a method and system for evaluating navigation efficiency based on gravity lighthouses. Background technique [0002] Traditionally, the evaluation method for submarine navigation accuracy is as follows: the submarine sails near the sea surface, releases the optical cable connected to the GNSS receiving antenna, compares the positioning data of the navigation satellite with the positioning result of the submarine navigation system, and calculates the mean square error of the two. as the final evaluation index. This method does not take into account the environment of the marine area where the submarine sails, and the comparison indicators are one-sided, making it difficult to make an effective and comprehensive definition of the advantages and disadvantages of the navigation system. Contents of the invention [0003] The purpose of the present invention ...
