In this paper, the authors propose a new method of signal tracking technique in Global Navigation Satellite System (GNSS). It is based on a combination of the AutoCorrelation Function (ACF) with another cross correlation function in order to eliminate or reduce the power of the side peaks in ACF of Binary Offset Carrier (BOC) modulated signals. This type of modulated signals is adopted by both GNSSs like the modernized Global Positioning System (GPS) and Galileo. Moreover, this method still keep the sharp of main peak of ACF in order to maintain the advantage of BOC (n,n) signals in code tracking and multipath mitigation.
