针对伽利略信号调制的特点,提出了一种基于滤波相关器法的多路径消除方法ELSC(early-late strobe correlator).通过对滤波相关器法应用于伽利略E1信号的跟踪情况进行分析,发现滤波相关器法不能消除延迟为0.5个码片附近的多路径信号影响.ELSC方法通过对几个滤波相关器的叠加,能有效消除0.5个码片附近的多路径信号影响.通过仿真比较了ELSC方法和滤波相关器法对于伽利略信号的多路径误差包络.结果表明ELSC方法优于传统的滤波相关器法,不仅适用于伽利略信号的跟踪,同时也适用于GPS信号的跟踪. Aiming at the characteristics of Galileo signal modulation, an early-late strobe correlator (ELSC) based on the filter correlator method is proposed. By analyzing the tracking of the Galileo E1 signal by the filter correlator method, it is found that the filter correlation The method can not eliminate the influence of multipath signal with the delay of 0.5 chips.The ELSC method can effectively eliminate the influence of multipath signals around 0.5 chips by superposing several filter correlators.Through the comparison of ELSC method and The results show that the ELSC method is superior to the traditional filter correlator method, which is not only suitable for the tracking of Galileo signal but also for the tracking of GPS signal.
