The paper deals with an optimal processing of a Galileo E5 signal. A proposed correlator struc-ture was developed on a base of a deep study of an E5 signal cross correlation function. Due to the non linear-ity of the E5 AltBOC modulation the proposed correlator calculates the cross correlation function between a received signal and a signal replica for all possible hypotheses of the navigation message bits. A correct peak tracking verification is realized by implementation of a single side band correlator, which also serves for course signal acquisition and secondary ranging code synchronization. The signal processing was verified on the Galileo Giove A and Giove B satellites with very positive preliminary results.
