| 摘 要： | 多径是影响卫星定位系统的主要因素，因此如何消除多径成为提高定位精度的重要任务。以Galileo接收机为基础来研究多径的抑制。主要介绍了Galileo信号和多径信号的基本结构，通过对多径消除方法——窄相关技术的仿真，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。

| Abstract: | Multipath is the main error in the global position system, so the method of multipath mitigation is becoming an important mission. Galileo receiver was studies based on the multipath mitigation, and the BOC signal in Galileo system and the multipath signal was introduced. The simulation of the narrow correlation in the multipath mitigation shows that the tracking error is mostly mitigated, and the precision of the tracking is also enhanced. |
