Galileo接收机中窄相关技术的分析与研究

Study on narrow correlator technology based on Galileo receiver

将窄相关技术应用到Galileo系统中进行分析和研究具有非常实际的意义。主要介绍了Galileo信号的基本结构,根据延迟锁相环的基本结构分析了其多径误差函数。通过对跟踪误差函数方差的仿真分析,可以看出窄相关技术对跟踪误差有很好的抑制能力,能提高测量精度。

Applying the narrow correlator technology to the Galileo system is of practical value. The basic structure of Galileo signal was introduced, and based on the structure of delay lock loop, the error function of the muhipath was analyzed. The simulation results of the variance of the tracking en＇or function indicate that the tracking error is mostly mitigated, and the precision of the tracking is enhanced.
