关于GPS高程测量精度的分析比较

Analysis and Comparison on the Accuracy of GPS Height Measurement

近年来,GPS技术得到了广泛的应用,但是科学数据表明,GPS高程测量精度还受到一些因素的影响,因此,限制了GPS测量功能的发挥。为了使GPS高程测量在实际中得到更加广泛的应用,本文对GPS高程测量的基本原理和影响因素进行了分析,经过比较,重点研究如何提高GPS高程测量精度。

In recent years, GPS technology has been widely used, but the scientific data show that GPS elevation measurement accura-cy is also affected by some factors, which limits the GPS measurement function to play. In order to get more extensive application in the actual GPS height measurement, this paper for GPS height measurement basic principle and influence factors are analyzed, through comparative analysis, focusing on how to improve the accuracy of GPS height measurement.
