摘要

摘要: 针对Galileo系统双频与三频组合三频单点定位（SPP）精度分析问题，本文基于MGEX跟踪站Galileo多频实测数据，分析了Galileo系统双频与三频组合SPP定位精度.发现Galileo系统E1/E5a和E1/E5b双频组合SPP定位精度较高，而E5a/E5b和E1/E6双频组合SPP定位精度过差，不适合进行定位，三频SPP定位精度较双频组合有明显提升，X和Y方向定位精度优于0.8 m，Z方向精度优于2.3 m，可为今后Galileo系统多频组合定位研究提供一定参考.

Abstract: Aiming at the problem of analyzing the accuracy of the dual-frequency and triple-frequency combined SPP positioning of the Galileo system, this paper analyzes the dual-frequency and three-frequency combined SPP positioning accuracy of the Galileo system based on the measured data of the Galileo MEGX tracking station. It is found that the Galileo system E1/E5a and E1/E5b dual-frequency combination SPP positioning accuracy is higher, while the E5a/E5b and E1/E6 dual-frequency combination SPP positioning accuracy is too poor, not suitable for positioning. There is significant improvement in positioning accuracy of the three-frequency SPP than the dual-frequency combination. The positioning accuracy in the X and Y directions is better than 0.8 m, and the accuracy in the Z direction is better than 2.3 m, which can provide a certain reference for future research on the multi-frequency combined positioning of the Galileo system.
