摘要
Galileo系统是当前常用的定位系统之一,本文作者利用自编软件进行了一种非组合模型下Galileo系统双频与三频短基线解算试验.经研究发现:对于9km短基线,非组合模型下Galileo双频短基线解算水平精度优于5 cm,高程精度优于10 cm,三频组合解算精度较双频有明显提升,水平精度优于3 cm,高程精度优于4 cm.
Galileo system is one of the commonly used positioning systems at present.This paper uses self-edited software to carry out a dual-frequency and triple-frequency short baseline solution experiment of Galileo system under the condition of non-combined model.Research has found that for a 9 km short baseline,the Galileo dual-frequency short baseline solution under the non-combined model has a horizontal accuracy better than 5 cm,and an elevation accuracy better than 10 cm.The triple-frequency combined solution accuracy is significantly improved compared with that of dual-frequency.The horizontal accuracy is better than 3 cm.The elevation accuracy is better than 4 cm.
