| 摘 要： | 卫星定位通信系统是具有10米以内高精度的第二代卫星导航定位系统。达到高精度的关键是应用了伪随机码扩谱及差分定位技术。诸如星历误差、电离层时延变化和地球模型不准等误差,通过应用差分技术可以大部分消除。本文阐述了差分技术的应用和系统精度分析。

| Abstract: | Radio Determination Satellite Service is one of the second generation satellite navigation-position fixing systems which posseses high accuracy in position within 10m. Spread-spectrum PN code ranging and differential Posi tioning technology are used to make it possible to reach such accuracy. Errors, such as ionospheric delay variations, satellite ephemeric errors and the shape uncertainty of the earth (the geoid) can be largly compensated by using differential technology.The differential technology and system accuracy analysis are described in this paper. |
