Detailed Analysis of the Impact of the Code Doppler on the Acquisition Performance of New GNSS Signals

Abstract:	For several tens of years, when the main acquired signal was GPS L1 C/A and under normal circumstances, many results were derived assuming that there is no change in the received code frequency due to the incoming Doppler frequency. Nevertheless, [1] and [2] investigated the effect of the resulting code phase sliding during the correlation process and showed that the acquisition performance can significantly be degraded. Considering the new challenges (new environments and new modulations, signal structures, longer codes, faster code rate, and so on), this investigation needs to be reviewed. In this paper, the authors want to present some results dealing with the code Doppler effect on acquisition performances for several new GNSS signals.
