摘要
介绍了GPS/GLONASS组合导航定位的基本原理,分析了需要解决的技术难点,比较了4阶、8阶RK(Runge-Kutta)数值积分方法,针对GPS、GLONASS两类观测值合理定权进行了讨论,利用一组实测数据,进行了组合定位的实际计算,分析了不同方案的伪距实时定位精度。
The basic principle of combined GPS/GLONASS single-point positioning was introduced and the key technical points were analyzed. Then the differences between the 4th order RK method and 8th order RK method was compared. The reasonable determination of the weights for two kinds of observations were researched, computed an actual example to get the practical positioning accuracy and drew some conclusions.
