We propose two versions of a baseband modulation
scheme, based on a chirp-type signal, that allow to improve
the performance of Global Navigation Satellite System (GNSS)
receivers in the presence of channel additive white Gaussian
noise, narrowband interference and multipath. Different signaling
schemes, characterized by autocorrelation functions with small
secondary peaks, are obtained by adjusting two parameters.
The advantages of the proposed schemes regarding modulations
BOC(1,1) and CBOCpilot are highlighted.
