GPS相位测量轨道改进基线定位

利用GPS载波相位观测值进行基线测定具有重要意义。本文讨论了基线测定中卫星星历误差对定位结果的影响,提出了基线上轨道改进的定位方法,编制了基线测定的定位软件,并使用高精度基线上的实际观测资料进行了计算。计算结果表明在基线上用轨道改进定位方法是可行的,可以提高定位精度。

GPS ORBIT IMPROVEMENT AND RELATIVE POSITIONING FROM THE PHASE OBSERVABLE ON BASELINE

Using the GPS phase observable for baseline determination is very useful, In this paper, we discuss the influence of the error of the GPS ephemerides about positioning, and give the method of orbit improvement on a baseline. The research results show that the method of the orbit improvement and relative positioning can obtain a better accuracy, we illustrate this technique by processing phase observations of baselines.
