Abstract

In this paper, we see the acquisition and tracking of L1 C/A signal on GPS receiver, do the research on GPS signal capture principle's foundation, and do the simulation of the GPS signals capture process for it's realizing and analyzing by Matlab. The simulation result, we can confirm this method's accuracy and the feasibility, and see that a satellite receiving ability play an important role in the efficiency of receiver.

본 논문에서는 GPS 수신기에서 L1 C/A 신호의 포착과 추적을 이해하고, GPS 수신기 신호의 수신에 관해서 연구하고, GPS 신호 수신과정에 관해서 Matlab을 사용해서 모의실험을 한다. 실험한 결과, 우리가 실행한 방법의 정확성과 가능성을 확인할 수 있었고, GPS 수신기의 성능은 위성의 수신능력이 매우 중요하다는 것을 알 수 있었다.
