| 摘 要： | 介绍星站差分GPS的原理。通过SF-2050G型星站差分GPS在长江王家渡水道的应用测试,分析了星站差分GPS较传统差分GPS的优势:无需建立GPS本地基准站,单机作业便能大范围应用,并且随着时间的增长其定位精度可收敛至5 cm。测试结果证明星站差分GPS能稳定、高效、高精度地应用于水下地形测量。

| Abstract: | The principle of Starfire WADGPS technology was introduced.Based on the application of SF-2050G type WADGPS in an underwater topographic survey of the Wangjiadu channel of the Yangtze River,the advantages of the Starfire WADGPS,as compared with the traditional DGPS,were pointed out: without needing for a local GPS base station,single pieces of its equipment can be used for large-scale survey with its precision that can reach 5cm.Test results show that the Starfire WADGPS is highly stable,highly efficient and highly precise in underwater topographic surveys. |
