火箭橇滑轨基准线高精度GPS测量数据处理

High precision GPS data processing in the measurement of rocket sled rail baseline

本文介绍了GAMIT软件对GPS观测数据解算基线向量的过程和方法,通过对网平差结果与精密光电测距比较,进行精度指标统计分析。结果表明本文方法可靠强性、精度高,为GPS技术在同类型精密工程中的应用提供了一定的参考借鉴和经验。

In this paper, the procedure and strategies for processing GPS observations by GAMIT is first presented in detail. And then, the results of networks adjustments of precise electro-optical distance measurements with some field experiments are compared with that of GPS. The results indicate the accuracy and reliability of GPS can be improved and meet the requirements for such special engineering project.
