A New Multipath and Noise Mitigation Technique Using Data / Data-less Navigation Signals

Olivier Julien, Gérard Lachapelle and M. Elizabeth Cannon

Abstract:	Modernized GPS and Galileo will be available to civil users at the end of this decade. Their signal structure design will bring tremendous improvement for any user compared to current GPS. One important advance, which is the focus of this paper, is the availability of data and pilot (or data-less) channels wrapped in a Quadrature Phase Shift Keying (QPSK) modulation (or similar). The presence of a pilot channel will allow for a more effective tracking of the carrier, bringing lower loss of lock
