GNSS Interference Monitoring
GNSS interference monitoring tracks disruptions to satellite navigation signals in real time. GPS is part of the Global Navigation Satellite System (GNSS); GPSwise detects interference to GNSS-based positioning worldwide using ADS-B data from aircraft.
Types of GNSS Interference
- GPS spoofing – False signals mislead receivers about location (e.g., aircraft at position A appears at position B).
- GPS jamming – Signals are blocked entirely, preventing position determination.
Why Monitor GNSS Interference?
Interference affects delivery services, maritime, and air traffic—with more severe consequences for aviation and maritime operations. Real-time monitoring helps protect transportation, logistics, and critical infrastructure that rely on accurate GPS data.
How GPSwise Monitors Interference
GPSwise uses real-time ADS-B data from the OpenSky Network to detect and track potential GPS spoofing and jamming incidents worldwide, displaying them on an interactive map. See How GPSwise Works for technical details.
