PPP技术在水深测量成果质量检验中的可行性研究

Feasibility Study of the Precise Point Positioning in the Depth Measurement Reswts of Quality Inspection

传统的水深测量方法已不能满足当今水深测量精度要求,随着PPP技术的不断发展,其动态定位精度已可以达到厘米级,而且作业模式灵活高效。本文主要探讨了利用PPP技术进行水深测量的基本原理和作业步骤,从多个方面分析了其精度及可靠性,给出了相应的作业要求,并讨论了其用于水深测量成果质量检测的优点。

Traditional method of bathymetry can not satisfy the demand of precision nowadays,with the development of PPP theory,its dynamic positioning precision can be ready to cm grade,besides its active and high efficient task mode.This article explores the basic principle and operation steps in the bathymetry using PPP technique at first,then analyses its credibility in surveying precision,at the same time,gives the operation demands,at the last,the paper has explored the advantage of the theory in bathymetry product quality check.
