GPS-RTK在海洋测量中的应用

Application of GPS-RTK in Marine Surveying

目前,常规水下地形测量技术验潮模式即(采用GPS获取平面坐标,测深仪获取深度数据,再由岸上人员定期观察水位值这种模式)已经不能满足海洋水上测量实际要求。随着GPS技术的不断发展,特别是RTK技术的出现,使得水上测量可以采用GPS无验潮方式进行工作(RTK方式)成为现实。作者结合沿海工程水下地形测量的工作,对这种测量方法进行总结和分析,提出了自己见地。

At present, the conventional underwater topography measurement technology tidal model, namely using GPS for plane coordinates, using sounders to get depth data, and then the shore professionals observe water level value, cannot meet the actual requirement of oeean water measure. With the eontinuous development of GPS technology, especially RTK technology, water measure can be made by using GPS without tidal manner （RTK way）. Based on the coastal engineering measurement of underwater topography, the article made the summary and analysis of this kind of measurement method, and suggestions are put forward.
