چکیده
Abstract Multipath propagation is a major source of error in global navigation satellite systems (GNSSs), especially urban environments. This because conventional GNSS receivers can provide biased range estimates that lead to positioning errors. In this paper, an Extended Kalman Filter (EKF)-based solution relies on multi-correlator structure proposed replace the delay locked loop (DLL). The underlying signal model incorporates radio channel between and receiver thus inherently accounts for reflected replicas. algorithm was evaluated with simulations hardware emulations measurement campaign conducted road traffic different multipath Our results revealed EKF very effective against multipath-associated error.

Multipath Mitigation Using Particle Filtering
In direct–sequence spread–spectrum (DS–SS) based navigation systems, multipath can degrade seriously synchronization performance causing time delay and code phase estimates to deviate from the actual value. This bias depends on the relative amplitudes and delays of multipath replicas with respect to the direct signal. The error in the estimated position due to multipath, when using a standard D...
متن کاملA New Multipath and Noise Mitigation Technique Using Data / Data-less Navigation Signals
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 o...
