| 摘 要： | 基于GAMIT TRACK双差动态定位模块计算海洋潮汐.将不同基线组合下的计算结果分别与压力式验潮仪记录值比对,验证该方法的可行性和适应性;比较不同星历和基线组合的结果,得出在150km基线以内,采用IGS最终星历得到的潮位变化结果精度最高,但不具备实时性;超快速星历结果精度稍次之,可以用于实时GPS验潮;广播星历结果...

| Abstract: | Based on GPS differential phase kinematic positioning program of GAMIT TRACK,ocean tide is calculated in this paper.By comparing the results of combination of different baselines with recorded values of pressure tide gauge,this method is proved feasible and appropriate.By comparing the results of different combinations of ephemeris and baselines,it is concluded that,when the relative-positioning distance is within 150 km,the tide produced with IGS final ephemeris is the most precise one but lags,and the IGS ultra rapid product which can be used in real time GPS tide observing comes second,and the result of the broadcast ephemeris is the worst and only can be applied to real time short baseline GPS tide observing. |
