摘　　要：本文介绍一种船载的水声定位系统精度标定方法。以船载模拟声源作为合作信标结合差分GPS、姿态监测装置建立动态基准点。采用系统偏差和标准差精确解算水下声导航定位系统的定位精度,可为水声定位系统提供海上定位校验的位置标准,并对试验所需最佳阵型和航路提供可靠参考和优化设计,从而提高试验结果的准确性。The paper introduces a kind of general underwater positioning system precision calibration method on boat. In the method,a dynamic benchmark is established through cooperating simulated sources on boat with star-station GPS and posture monitoring device. Using system error and root-mean-square deviation for calculating the positioning accuracy of underwater navigation and positioning system,the landtrial results show that the positioning error is less than 1 meter and the calibration system can provide the reference position for the underwater acoustic positioning system on the sea.
