高精度GPS差分定位技术辅助海上试验研究

High-Accuracy GPS Difference Position Technology Assistant Research of Sea Tests

越来越多的海上实船试验,对海上定位和测距的精度提出了更高的要求。此文利用国际先进的GPS接收机以及无线电数据传输系统组成了高精度差分卫星全球定位系统,实现达到1m(SEP)的实时动态高精度定位。同时利用时间同步模块,解决了海上试验的时统技术,在各种海上试验中发挥了重要的作用。

More and more sea tests put forwaras very high request for accuracy of position and distance measurement on the sea The author made up a high-accuracy DGPS,which consists of GPS receiver and radio data transimission system comparatively advanced in the world, so that the system realized real-time and dynamics high-accuracy position, the accuracy reaches Imeter(SEP). At the same time, the author resolved the timing technology making use of the time synchronization module, it plays a important role in various of sea tests.
