摘　　要：为了给出水下目标的精确大地坐标,设计了以浮筒作为载体的水下目标定位标校系统,具有灵活方便的优点。研究了影响系统定位误差的相关因素,并分析了系统综合定位精度,编写了标校系统显控软件,将差分GPS数据和方位姿态数据进行数据处理,解算出水下基准位置坐标。对标校系统进行了陆上验证试验,结果表明作为模拟目标的水下位置基准定位误差小于1m,可为水声定位系统提供海上定位校验的位置标准。Underwater acoustic target positioning system which uses a floating camel as carrier is designed to give out accurate geodetic coordinates.The factors influencing positioning precision and the integrated positioning accuracy are studied.The display and control software written for the system receives and processes the GPS and attitude data to calculate the geodetic coordinates of the underwater reference position.The land-trial results show that the positioning error is less than 1 meter and the calibration system can provide the reference position,which is regarded as a simulated target for the underwater acoustic positioning system on the sea.
