GNSS Jamming Practical Detection and Response Overview

Global Navigation Satellite Systems (GNSS), including GPS, Galileo, GLONASS and BeiDou, are widely used for navigation, tracking, fleet management, emergency service operations and timing. The increasing availability of low-cost GNSS jammers, together with more sophisticated spoofing techniques, creates an operational challenge for law enforcement and associated agencies. This one-day course gives participants a practical understanding of GNSS interference, how jamming and spoofing present in operational environments, and how suspected incidents should be recognised, recorded, escalated and investigated. The course deliberately compresses technical theory and emphasises field detection using the GPSPATRON GP-Probe Nano L1 detector/logger. Participants handle the detector, complete a baseline survey, interpret alert behaviour, capture logs or screenshots, and apply an evidence-focused incident workflow. Spoofing is covered as an awareness and escalation topic; the hands-on component is focused on practical jamming/interference detection and operational reporting rather than detailed RF direction finding or forensic GNSS analysis. This programme is suitable as a standalone operational overview and as a progression route into a fuller GNSS interference investigation course for delegates who require detailed spectrum-analysis, direction-finding, spoofing-investigation or evidential casework capability. Course Structure The course is structured as a one-day operational overview with practical detector handling. Timings and exercise emphasis can be tailored for police, border, transport, port, aviation, maritime or critical infrastructure audiences. Course Contents GNSS, Operational Dependency and Threat Drivers GNSS Jamming, Spoofing and Criminal Use Cases Operational Indicators, Triage and Reporting GPSPATRON GP-Probe Nano L1 Familiarisation Baseline Survey, Field Detection and Source Narrowing Legal, Evidence and Multi-Agency Escalation Scenario, Debrief and Next-Step Decisions Learning Objectives Participants completing this course will be able to: Explain how GNSS is used for operational tracking, navigation and timing, and why receiver-level interference can disrupt policing, transport and infrastructure activity. Distinguish at a practical level between GNSS jamming, spoofing, poor reception, multipath, receiver faults and tracking-platform anomalies. Recognise common criminal and public-safety use cases for GNSS interference, including vehicle theft, cargo crime, tracker evasion, drone-related disruption and critical infrastructure impacts. Use the GPSPATRON GP-Probe Nano L1 at a user level for detector/logger familiarisation, including device-status checking, detector/logger mode awareness, alert interpretation and Android-assisted visualisation where available. Conduct a structured baseline survey and preliminary source-narrowing activity using safe movement, signal-strength observations, approach/retreat checks and appropriate supervision.
