Abstract:The Global Navigation Satellite System (GNSS) is increasingly vulnerable to radio frequency interference (RFI), including jamming and spoofing, which threaten the integrity of navigation and timing services. This paper presents a methodology for detecting and classifying RFI events using low-cost commercial off-the-shelf (COTS) GNSS receivers. By combining carrier-to-noise ratio (C/N0) measurements with a calibrated received power metric, a two-dimensional detection space is constructed to identify and distinguish nominal, jammed, spoofed, and blocked signal conditions. The method is validated through both controlled jamming tests in Norway and real-world deployments in Poland, and the Southeast Mediterranean which have experienced such conditions. Results demonstrate that COTS-based detection, when properly calibrated, offers a viable and effective approach for GNSS RFI monitoring.
