| 摘 要： | 讨论了二次定位中声波定位方法和初至波定位方法误差的来源,指出由于多台GPS设备在不同的船上工作,众多设备统筹协调不好是造成二次定位存在较大系统误差的重要原因。在863课题支持下,开发了基于GPS的海上物探测量系统,该系统能统筹管理多台设备,实时完成导航、资料处理、绘图等多项功能,对提高生产效率,降低系统误差起到了重要作用。

| Abstract: | Ocean bottom cable (OBC) and hydrophones could deviate from its designed position due to current tide and the sped. It is very important to relocate the real positions of the hydrophone on seabed in order to acquire high quality seismic data. Based on study error of second positioning, the paper points out that the reason of error maybe come from many devices and equipments could not work correspondingly . We develop a new GPS geophysical survey system supported by "863" national project. The system could control many devices and instruments, complete navigation at real time, process seismic data and etc. the system would help reduce error of survey and work efficiently. |
