后处理DGPS在海域调查中的研究与实践

Research and Application of DGPS Post-processing in Sea Area Survey

通过分析后处理差分全球定位系统(d ifferential global position ing system,DGPS)测量原理和其在海域调查中应用的具体事例,说明DGPS不仅使用方便、定位精度高,而且价格低廉,对其在海洋测绘领域的应用很有必要。

This paper presents the survey principle and practical examples of the post-processing of DGPS （ differential global positioning system） and shows that DGPS is low-coat, easy to use and obtains high-precision position. It is up-to-date significant and academically valuable to make research on the application of DGPS in hydrography. DGPS costs cheap, operates conveniently and gets high-precision position. The study has actually action and academic value on the sea water area survey.
