摘要
卫星信号的同步包括捕获与跟踪两个过程,同步算法在GPS软件接收机的设计中占有十分重要的地位.本文对GPS卫星信号P码的捕获与跟踪算法进行了研究,完成了该算法在MATLAB 6.5环境下的仿真验证,并对仿真结果进行了分析.
The synchronization of GPS signals plays a key role in the design of GPS software receivers, which consists of two parts called signals＇capture and signals＇tracking. In this paper, an algorithm of P-code signals ＂capture and signals＂ tracking is described, and based on it, the simulation of algorithm is designed. Mean- while, the result of the simulation is analyzed.
