| Abstract: | GPS (Global Position System) is an effective way employed in urban rail transit systems to guarantee the safe and fast running of trains. Adopting Matlab/Simulink software to simulate GPS signals and inputting these signals into the PC, authors of the paper realized the acquisition and tracking algorithm and verified the algorithm. |
