利用广播星历及伪距进行单历元单点定位，通过精度比较分析，得出GPS定位精度优于GLONASS，组合系统优于单系统；同时给出了初步的定权方案。
利用廣播星歷及偽距進行單歷元單點定位，通過精度比較分析，得齣GPS定位精度優于GLONASS，組閤繫統優于單繫統；同時給齣瞭初步的定權方案。
이용엄파성력급위거진행단역원단점정위，통과정도비교분석，득출GPS정위정도우우GLONASS，조합계통우우단계통；동시급출료초보적정권방안。
broadcast ephemeris and pseuclorange is use（：[ to single point pomnonlng epocn by epoch. Positioning accuracies were compared that positioning accuracy by GPS is better than GLONASS, and combined system is better than single system . An initiative weighting method was also recommended.
