摘要
A satellite signal multi-pass tracking system capable of obtaining more accurate navigation data using a main-peak quality of a GPS and Galileo satellite signal is disclosed. To achieve this, the present invention is a satellite signal multi-pass tracking system using the main-peak quality of the GPS and Galileo satellite signal. The present invention comprises: a signal obtaining module to find a BOC signal having the sharp main-peak by comparing a autocorrelation result between the binary offset carrier (BOC) signal modulated from a satellite signal of the Galileo and the BPSK signal modulated from a satellite signal of the GPS, and to obtain Doppler frequency information and code phase information using the found BOC signal; a signal tracking module to track a carrier wave and a code for the GPS and the Galileo using the Doppler frequency information and the code phase obtained by the signal obtaining module; and a navigation data extraction module to extract the autocorrelation data using the carrier wave and the code tracked in the signal tracking module, and to extract the navigation data and frame synchronization by receiving a bit line of the extracted autocorrelation data.;COPYRIGHT KIPO 2015
