摘要
岛礁测量对于我国海洋国土管理具有重要作用。在无基础控制网的海域,利用星站差分系统可以高效完成测量工作,其精度能满足岛礁测量的相关规范要求。介绍了星站差分系统的基本原理,阐述了星站差分系统在远海岛礁测量中的应用,将其与传统的GPS测量方法进行了比较,分析了星站差分系统在远海岛礁测量中的优势,并进行了测量实验和精度分析。
The measurement of island and reef plays an important role in China’s marine land management.In the sea area without the basic control network,the star-station differential GPS system can be used to complete the measurement work efficiently,and its accuracy can meet the requirements of relevant specifications of island and reef measurement.In this paper,we introduced the principle of satellite system,expounded the application of star-station differential GPS system in offshore island and reef measurement.Then,we compared the star-station differential GPS system with the traditional system,and analyzed the advantages of star-station differential GPS system in offshore island and reef measurement.Finally,we carried out the precision analysis by measurement experiment.
