| 摘 要： | 针对岛礁周围海洋环境测量的位置保障需求,以具备NavCom的StarFire差分服务的调查测量母船作为基准站,机动测量测量艇作为流动站,通过动态RTK的模式进行定位。设计了固定流动站、基准站与流动站相对位置固定和基准站与流动站相对运动3种场景对NavCom GPS差分定位系统的性能进行了分析研究,结果表明动态RTK模式下NavCom GPS差分定位系统可获得分米-亚米级的精度。

| Abstract: | With the positioning requirement of ocean environment surveying around the reefs,the hydrographic survey vessel which possesses the positioning ability by using the StarFire differential service of NavCom is acted as base station,the mobile surveying boat is acted as rover station.Three scenes of fixed rover station,fixed relative range of base and rover station,and relative motion of base and rover station are designed to analyze and research the performance of NavCom GPS Differential Positioning System,the result shows that the NavCom GPS Differential Positioning System can reach the accuracy level of decimetre-sub meter. |
