Due to the low level of the received power and to the known signal structure, Global Navigation Satellite Systems (GNSS) civil signals might be vulnerable ...
In this paper we present the results of a set of live experiments in which the Chi-square GoF test is applied at the correlators output of a real-time software ...
Unless the spoofer is able to generate a phasealigned nulling signal, residual authentic GNSS signal components remain in addition to the counterfeit signals.
This paper proposes a spoofing detection metric called ACF similarity, which employs a feature extraction method in the field of image processing.
Post-correlation signal analysis to detect spoofing attacks in GNSS receivers (English) · ISBN: 978-0-9928-6265-7 · ISSN: 2076-1465 · Conference paper / Electronic ...
A novel spoofing detection method entitled aggregated correlation residue likelihood analysis (A-CoRLiAn) is proposed in this study.

In this method, the tracked GNSS signal subtracted from the correlation results, and the residual signal captured or tracked once again, by testing whether ...
Dec 17, 2024 · We propose a new dedicated complex metric as the figure of merit to improve the robustness and efficiency of spoofing detection.
Oct 3, 2022 · This new method makes it possible to decompose the Complex Cross Ambiguity Function of GNSS signals during malicious spoofing attacks.
Abstract—This work proposes a novel sparsity-based decomposition method for the correlator output signals in GPS receivers capable of detecting spoofing ...
