| 摘 要： | 本文利用IGS 5个站的观测数据分7个时段进行了GPS/GLONASS组合精密单点定位计算,与单独GPS精密单点定位的结果在精度和收敛时间方面进行了性能比较。结果表明,在当前GPS卫星数量充足的情况下,增加少量的GLONASS卫星对定位精度的提高帮助不大,但能显著改善滤波收敛的时间。

| Abstract: | The computation of combined GPS/GLONASS Precise Point Positioning(PPP) was conducted in seven sessions using static data from five IGS observation stations.The performance was assessed in terms of converged position accuracy and convergence time with a comparison to that of GPS-only.The results indicated that adding a few GLONASS satellites would not contribute to improving positioning accuracy at the situation of currently sufficient GPS satellites.However,the convergence time could be improved significantly. |
