FJCORS 与测深仪组合系统在水下地形测量中的质检探讨

根据连续运行卫星定位服务系统可实时获取三维坐标、测深仪可实时获取水深数据的特点，提出水下地形测量中快速获取水下地形点高程和水深的方法。 FJCORS和测深仪组合系统不但广泛应用于水下地形测量，而且还可对其成果质量进行检查和分析，确保成果数据的可靠性，保证水下地形测量成果合格。

Discussion on the Quality Inspection of Underwater Topographic Survey Using the Combined System of the FJCORS and the Depth Finder

Based on the continuously operating reference stations achieving 3D coordinates and the depth finder achieving water depth data in real time, the rapid acquisition method of underwater topographic survey is put forward on terrain height and depth.The combi-nation system of FJCORS and the depth finder are widely used in underwater topographic surveying and the quality of the results should be inspected, so as to ensure the reliability of survey data.
