| 摘 要： | 首先给出了基于GNSS-MR技术提取潮波系数的原理与方法,然后利用布设在浙江省石浦港验潮室屋顶的GPS站DSPU实测数据对潮波系数进行了提取,并与验潮站实测潮位调和分析结果进行了对比分析。实验结果表明GPS-MR反演潮位与验潮站实测潮位值吻合较好,相关系数优于0.97;GPS-MR反演潮位与验潮站实测潮位获取的潮波系数基本一致,除M2、S2外其它差异较小。两者获取的潮波系数差异主要因为DSPU测站观测环境极大地影响了GPS-MR提取潮位精度。沿海GNSS站用于潮位监测和潮波系数提取,将进一步拓展沿海GNSS监测站的应用领域,在一定程度上可弥补验潮站的不足。

| Abstract: | The principle and method of extracting tidal coefficients based on GNSS-MR technology are firstly given.Then,the tidal coefficients are extracted by using the DSPU measured data of the GPS station installed on the roof of the tidal chamber of Shipu Port,Zhejiang Province,and compared with the measured tide level harmonic analysis results of the tide gauge station.The experimental results show that the GPS-MR inversion tidal level agrees well with the measured tide level of the tide gauge station,and the correlation coefficient is better than 0.97.GPS-MR inversion tide and tidal stations found tide coefficient obtained consistent tidal wave,in addition to M2,S2 other minor differences.Coefficient difference of both tidal wave acquired station mainly due to the observation conditions DSPU greatly affects the accuracy of GPS-MR extraction tide.GNSS monitoring stations along the coast for tide and tidal coefficient extraction,will further expand the application field of GNSS monitoring stations along the coast,to a certain extent,can compensate for the lack of tidal stations. |
