Dual-Satellite Doppler Accuracy Prediction and Geometry Selection for Sparse LEO Signals of Opportunity
Qi Liu, Marc Fernández-Temprado, Antoni Reus-Bergas +4
Low Earth Orbit (LEO) satellites have emerged as a promising complement to GNSS for positioning in signal challenged environments. In sparse LEO signals of opportunity scenarios, D…
Geometric Performance Analysis of Doppler-Based Positioning with a Single LEO Satellite
Qi Liu, Marc Fernandez-Temprado, Antoni Reus-Bergas +2
Low Earth Orbit (LEO) satellites have gained increasing attention as potential signal sources for Positioning, Navigation and Timing (PNT) applications. However, while most existin…
Theoretical and Experimental Evaluation of AoA Estimation in Single-Anchor 5G Uplink Positioning
Thodoris Spanos, Fran Fabra, José A. López-Salcedo +4
As we move towards 6G, the demand for high-precision, cost-effective positioning solutions becomes increasingly critical. Single-anchor positioning offers a promising alternative t…
Angle of Arrival Estimation Using SRS in 5G NR Uplink Scenarios
Thodoris Spanos, Fran Fabra, José A. López-Salcedo +4
This paper presents a comprehensive exploration of Angle of Arrival (AoA) estimation techniques in 5G environments, using the Sounding Reference Signal (SRS) in Uplink scenarios bo…
Optimal Post-Detection Integration Technique for the Reacquisition of Weak GNSS Signals
David Gómez-Casco, José A. López-Salcedo, Gonzalo Seco-Granados
This paper tackles the problem of finding the optimal non-coherent detector for the reacquisition of weak Global Navigation Satellite System (GNSS) signals in the presence of bits…
