摘要
Abstract
The problems existing in attitude measurement and correction of the shipborne acoustic positioning system are analyzed and researched. The system′s positioning error caused by attitude angle was simulated with the attitude angle correction formula. The results show that the heading angle impacts the positioning error more under the same conditions,and the positioning accuracy in the different orientation is different. The compound mode combining GPS/Beidou satellite cascade with miniature iner⁃tial navigation is adopted to execute the ship attitude measurement. The result of testing in a lake proves that the program have the high measurement accuracy,fast data update rate and simple implementation,and can satisfy the demands of shipborne acoustic positioning system. The program has been applied to a specific type of underwater sound positioning system. It has high practical value.关键词
