| Abstract: | 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. |
