摘要: 主要论述改装GPS发射的同步信号是否可被R2 SINC 2024识别,多波束系统是否可以利用GPS RTK高精度定位技术实现无验潮作业。通过改装LEICA GPS,加入PPS秒脉冲发射模块,为多波束系统提供同步信号。并经过野外实验结果分析,改装的LEICA GPS PPS秒脉冲发射模块可以被R2 SINC 2024识别,同时由于采用GPS RTK输出的高精度定位信息,显著提高了多波束系统扫测的水深数据质量。

Abstract: This paper mainly discussed whether the modified synchronous signal of GPS emission could be recognized by R2 SINC 2024, whether multi beam system could use the GPS RTK high precision positioning technique without tidal operations. By modifying the LEICA GPS, joining the PPS second pulse transmitting module, synchronous signal were provided for multi-beam system. By analyzing the results of field experiments, modified LEICA GPS PPS second pulse transmitting module can be identified by R2 SINC 2024, at the same time, because of the high precision positioning information using the GPS RTK output, the quality of multi beam system bathymetric data was significantly improved.
