摘要

为了缩短GNSS接收机捕获信号所用的时间，在对导航信号进行频谱观察的基础上，改进了基于FFT的捕获算法和阈值的设定，并对改进后的算法进行了仿真验证，结果表明该算法具有可行性，并可以缩短捕获时间。设计了GNSS接收机的完整跟踪通道，利用MATLAB软件对该跟踪通道进行仿真，仿真结果验证了该跟踪通道的正确性。

Abstract

Based on the observation of frequency spectrum of navigation signal

an improved FFT acquisition algorithm was proposed which could reduce the capturing time of GNSS receiver

the threshold of the algorithm was also modified. Simulation results show that the new algorithm can shorter capturing time. The complete tracking channel of the GNSS receiver was also designed

and the MATLAB simulation results verify the correctness of the proposed tracking channel.
