Ionospheric residuals from empirical models exhibit strong spatiotemporal correlations, posing a dominant error that undermines the integrity and robustness of single-frequency Global Navigation Satellite System (GNSS) applications, for example, in the aviation industry. This study develops a unified Gauss–Markov (GM)...

Conventional Global Navigation Satellite System (GNSS) Direct Position Estimation (DPE) exploits raw intermediate-frequency (IF) data and provides a full-information Cram\'er-Rao Bound (CRB) benchmark, but its accumulated-correlation objective requires dense evaluations over a common Position, Velocity, and Time (PVT)...

A multi-frequency cross-product area (MF-CPA) framework for multipath detection using only standard early-prompt-late I/Q correlator outputs, requiring no receiver modification, provides a scalable and interpretable solution for robust multipath monitoring in next-generation wireless navigation systems.
