摘要
研究了动态环境下导航信号跟踪环路中环路滤波器的设计,首先根据导航接收机的动态确定了二阶的码跟踪环和频率跟踪环以及三阶的载波相位跟踪环,然后以软件的方式设计了对应的数字环路滤波器,最后给出了环路滤波器参数的确定方法。
Tracking loop filters design for navigation signal in dynamic situation are studied in the paper.Firstly,the second order tracking loops for PN code tracking and frequency tracking and the third order tracking loop for carrier phase are given.Then digital tracking loop filters of all tracking loops are design by software.Finally,the parameters of the tracking loop filters are given.
