目前,水道地形测量模式已基本定型于利用GPS测定水底点的平面位置,利用测深仪测定水底点的水深,附之以瞬时潮位或水位资料,获得点位的高程。随着各地连续运行卫星定位服务系统的投入运行,本文提出了一种无验潮模式下的水道地形测量模式,即不测定潮位或水位,而直接利用HBCORS的RTK测量技术,从而获得高精度的水底点高程。本文通过实际工程,用无验潮模式与传统模式在精度上进行对比,得出了该方法在精度上和效率上都有很大的提高,值得推广应用的结论。

The current waterway terrain model has basic finalize the measurement using GPS to determine the plane position at the bot -tom, using sounding analyzer to measure underwater point of water depth , attached to the instantaneous tide levels or water level mate-rial, get the point elevation .With the continuous running all over satellite positioning services to put into operation of the system , this paper puts forward a no tidal mode of waterways terrain measurement model , that is, not determine tide levels or water level , and di-rectly for the use of the HBCORS RTK measurement technology , assisted by attitude compensation , so as to achieve high precision at the bottom elevation .This article through the practical engineering , with no tidal model and the traditional mode in the accuracy is compared, and that the method in the accuracy and efficiency are greatly improved , popularization.
