GNSS spoofing and jamming threats undermine RTK positioning accuracy, requiring field validation protocols
GNSS spoofing and jamming can cause significant disruptions to Real-Time Kinematic (RTK) positioning systems used in satellite navigation. Jamming typically results in loss of satellite lock and degraded signal quality causing RTK solutions to downgrade from fixed to float or standalone modes. Spoofing, on the other hand, injects counterfeit satellite signals that may produce stable but incorrect coordinates conflicting with verified control points. Field teams must distinguish these intentional interferences from common errors such as multipath reflections, signal obstructions, or correction data outages by cross-verifying receiver measurements with correction stream status and independent navigation aids. Recording detailed receiver states, correction ages, antenna status, and anomaly patterns allows teams to validate suspicious readings before relying on coordinates, protecting the integrity and safety of critical operations. The Federal Aviation Administration recommends best practices including monitoring for anomalies, confirming positions via alternative methods, and halting operations if data integrity is in question.
