摘要
通过分析影响定位精度的因素,给出了一种基于高度角和GDOP的组合选星算法,研究了其算法在GPS/GLONASS组合单点定位中的应用,在提高定位效率的同时提高了定位精度。结果表明,在动态定位中能快速选出较少的卫星组合用于定位解算,能满足动态用户对实时性的需求。
Through analyzing factors that influence positioning accuracy,we propose a new satellite selection algorithm based on GDOP and elevation of satellites.Applied to GPS/GLONASS combined single point positioning,this algorithm can improve the efficiency and accuracy of the positioning at the same time.In combined GPS/GLONASS kinematic positioning,selecting fewer satellites used for positioning quickly meet the real-time user＇s positioning needs.
