不同载波观测值线性组合对GPS基线解算的影响

The Influence of Different Linear Combination of the Carrier Observations on the GPS Baseline Solution

随着GPS定位技术在测量中的广泛应用,进一步提高GPS定位精度是当前测量领域研究的重点课题。基线解算是GPS数据处理中的重要环节。采用不同的载波观测值的线性组合对基线解算结果不同。本文首先介绍了载波观测值的线性组合理论,然后通过实测数据采用不同的线性组合进行GPS基线解算,分析解算结果,得到了一些有益结论。

With the GPS positioning technology widely used in the measurement,It is an important discussion that how to increase GPS positioning precision of current surveying field.The baseline processing is an importantpart in GPS data processing.Taking a different linear combination of observations have different the results of baseline solution.This paper introduces the main linear combination of carrier observations,then using different carrier observations and linear combination to solute GPS baseline,analysis results of solution,we obtain some useful conclusions finally.
