Tight Integration of GNSS and a 3D City Model for Robust Positioning in Urban Canyons
TL;DR: In this paper, a 3D Extended Kalman Filter (3D AEKF) was proposed for GNSS positioning in urban canyons by using constructively non-line-of-sight (NLOS) signals.
Journal ArticleDOI
Multipath Mitigation for GNSS Positioning in an Urban Environment Using Sparse Estimation
TL;DR: Experiments conducted with real GPS data show the effectiveness of the proposed method as long as the sparsity assumption is respected, and the weighting matrix of this algorithm is designed carefully as functions of the satellite carrier-to-noise density ratio and the satellite elevations.
Proceedings ArticleDOI
Acquisition of weak GNSS signals using a new block averaging pre-processing
TL;DR: This paper develops a software defined acquisition procedure using the efficient FFT correlation approach and proposes two acquisition algorithms based on the BAP approach, which implements the parallel code phase search in finding the 2-D spectrum peak using circular cross-correlations.

Robust tracking of weak GPS signals in multipath and jamming environments
Mohamed Sahmoudi,Moeness G. Amin +1 more
TL;DR: The resulting robust ML (RML) tracking procedure is more efficient in mitigating multipath and non-Gaussian interferences and the performance of the developed RML receiver is evaluated through computer simulations to show its superiority over that of narrow correlator and MEDLL approach.
