Abstract:	The Binary Offset Carrier (BOC) modulation, used in several carriers of Galileo and new generation GPS, provides enhanced robustness of these signals against multipath, increasing the precision of the navigation solution obtained in the receiver. However, this modulation presents some drawbacks, as the higher computational load required in the signal processing stage of the GNSS receivers, and the possibility to acquire and track a secondary peak of the BOC autocorrelation function, which reduces the received signal power and introduces a large bias in the computed pseudorange measurement. In this paper, an unambiguous lowcomplexity tracking technique for BOC(1,1) signals is proposed.
