GPS基线解算质量优化方法的研究

Research on the Quality Optimization of GPS Baseline Solution

GPS基线解算是GPS数据后处理的一项重要内容,针对实际工程中遇到的GPS基线解算得不到固定解的情况,首先总结了基线解算的质量控制指标,然后重点对影响GPS基线质量的主要因素进行分析,并以国产华测GPS的随机基线处理软件-Compass为例详细地介绍了如何消除上述影响的方法措施,最后对GPS基线成果的检验问题及超限纠正措施进行了讨论,并总结了一些实际工程中应注意的问题。

The job of baseline solution is very important in GPS data processing. In view of not getting the correct solution problems in data processing, this paper, summarizes the quality control targets of GPS baseline solution at fist, then analysis the main factors which effect the quality of GPS baseline. And take the software of HUCEA which named Compass as an example to introduce the solutions to solve the problems above in detail. Finally discuss the methods of testing the results and correcting the errors.
