摘要
研究了GPS基线解算中对测站坐标进行先验约束的影响,利用GAMIT/GLOBK软件分析了实测数据,得出了采用不同约束量对GPS基线解算结果的影响程度,并综合给出了GPS中采用先验约束的原则。
We researched the influence of the prior constraints to the station coordinates in the process of GPS baseline solution,then analyzed the field data with the software of GAMIT/GLOBK,and obtained the baseline solutions with different constraints.According to the results,we found the principle of prior constraints in GPS data analysis.
