Apparatus for Tracking GPS and Galileo Signal in GPS/Galileo Receiver

摘要

The present invention relates to a satellite signal tracking unit of GPS / Galileo receiver. ; The present invention GPS / Galileo in the satellite signal tracking unit of the receiver, receives the clock of a particular phase delay value set by a certain trailing L code groups, based on the P code, a specific phase having a specific phase , more than a certain lag behind VL code, the PRN code, including generating the estimation VE more advanced than a certain code delay value as the previous E code, and the specific delay value, which is correlated with the PRN code of the satellite signal and calculate a correlation value, The calculated correlation value, calculates the code phase error using the auto-correlation function and the weight of the BOC (1,1) signal, the estimated code phase error is output to track the satellite signal during the presence of the satellite signal tracking within the range PRN provide a satellite signal tracking unit of GPS / Galileo receiver, characterized by a particular phase of the control clock for the generation of code to be changed. ; According to the present invention, BOC (1,1) to resolve the ambiguity problems that occur in the modulated signal with a satellite tracking device that improves the performance of the satellite signal acquisition and tracking performance of GPS / Galileo receiver has the effect of providing.
