由海军海洋测绘研究所和国家海洋局海洋技术研究所联合研制的海洋大地测量水声定位系统于1988年7月15日通过鉴定。该系统采用超短基线定位原理,结构简单,操作方便,由计算机进行数据处理和直观显示,并可现场打印和磁带记录。作用距离超过5000米,测距精度高于1％,测向精度小于士5°(朱经摇摆修正)。到会专家一致认为该系统已全部达到或超过 The marine geodetic sound positioning system jointly developed by the Naval Institute of Marine Surveying and Mapping and the State Oceanic Administration Marine Technology Institute was appraised on July 15, 1988. The system uses ultra-short baseline positioning principle, the structure is simple, easy to operate, data processing and visual display by computer, and field printing and tape recording. Range of more than 5000 meters, ranging accuracy is higher than 1%, the accuracy of less than 5 ° direction of orientation (Zhu Jing swing correction). The experts agreed that the system has all met or exceeded
