Abstract
An acquisition and tracing algorithm of GPS receiver is introduced. The shortage of time domain acquisition algorithm is pointed out by analyzing the composition of GPS signal and C/A code’s correlation property. Then the frequency domain acquisition algorithm is discussed. The carrier wave track loop and C/A code track loop are designed and the algorithms of them are determined. Using these two loops can get the navigation message, etc that used for positioning and navigation. The GPS raw intermediate data is processed and the satellites signals are acquired and traced in MATLAB, then obtain the navigation message verified the feasibility and availability of the acquisition and tracing algorithm.
