| Abstract: | This paper explains the the concept of GPS,Pseudo Random Noise Code and structure of the GPS Signal,and describes the C/A code,P code and L2C code characteristics and methods of production in content of ranging codes of the GPS signal.Then the author simulates several usual Pseudo Random Noise Codes of GPS signal by MATLAB.The generated sequence is proved accurate after comparing to the real PRN.This paper provides a basis of research about how to receive and decode GPS staltite signal. |
