针对船载式水声定位系统的姿态测量及修正问题进行了分析与研究。利用姿态角修正公式对姿态角引起的系统定位误差进行仿真，仿真结果表明同等条件下航向角对其影响较大，并且系统不同方位上的定位精度不同。采用GPS/北斗卫星级联结合微型惯导的组合方式进行船体姿态测量，经过湖上实航试验证明，该方案测量精度高，数据率更新快，并且实施简单，能够满足船载式水声定位系统的需求。目前，该方案已在某型水声定位系统上得到了具体应用，具有较高工程实用价值。

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.
