| 摘 要： | 为了对水声定位测量系统进行海上校准,设计了以浮筒作为平台的水下目标轨迹测量标校系统,利用高精度DGPS和方位姿态仪解算出水下基准坐标并给出运动轨迹.具体研究了影响标校系统定位精度的相关因素,并给出系统的组合定位精度.对标校系统进行了陆上验证性试验,试验结果表明,标校系统的定位误差不超过50 cm,可对水声定位测量系统进行高精度的海上标校.

| Abstract: | The calibration system for measuring underwater acoustic target track using a floating pontoon as a carrier was designed to calibrate the acoustic positioning system on the sea.The high-accuracy DGPS receiver and gyroscope are used to gain the coordinate and moving track of the underwater datum mark.The elements influencing the accuracy of calibration system are studied,and the combined positioning accuracy is also presented.The land-trial results of the calibration system show that the positioning error is... |
