Recently, not only the legacy Global Positioning System (GPS) of the U.S., but also the next generation Global Navigation Satellite System (GNSS) which employs novel modulation techniques has been deployed, and, consequently, GNSS users can be provided more accurate location-based service. However, due to the various types of interferences in GNSS such as multipath, signal attenuation, thermal noise and cross correlation, it is still hard to obtain precise position information. For this reason, a number of researches have been carried out for robust GNSS against the above interferences, however, the effects of the cross correlation have been rarely studied compared to the effects of the other interferences, especially in the next generation GNSS. Therefore, in this paper, the effects of the Galileo E1 signal cross correlation are investigated. The effects of the cross correlation for relative Doppler frequency offset and dwell time are analyzed with simulation results.

Keywords: BOC, cross correlation, dwell time, relative Doppler frequency offset
