SeRo Systems has developed a GNSS Radio Frequency Interference (RFI) monitoring solution called SecureTrack, designed to provide visibility into navigation reliability across both airspace and ground environments. The system combines airspace monitoring with ground-based measurements to identify and analyze disruptions to GNSS signals.
In the airspace, SecureTrack uses ADS-B position reports along with multilateration-derived aircraft positions to detect aircraft affected by corrupted GNSS signals. This allows operators to observe where navigation performance may be degraded and understand how interference is impacting flight operations.
On the ground, the system monitors GNSS signals at airports and critical infrastructure to detect sources of jamming and spoofing. These measurements span multiple constellations, including GPS, GLONASS, Galileo, and BeiDou, and cover multiple frequency bands such as L1, L2, and L5. By combining these inputs, the platform provides a broader view of interference conditions across the monitored environment.
SecureTrack delivers real-time alerts when interference affects aircraft, enabling operators to respond as situations develop. A control-room interface presents this information through visual tools such as interference heatmaps, spoofing detection views, and time-based waterfall charts, helping users interpret both the severity and evolution of GNSS disruptions.
The system also supports investigation and reporting workflows. It records GNSS performance data in compliance with ICAO Annex 10 Volume 1 and enables historical analysis across both air and ground monitoring domains. Analytical tools allow users to generate statistics, examine affected flights, and export data in formats such as CSV or KML for further review.
Additional capabilities include spectrum visualization using FFT analysis, access to internal GNSS receiver data such as satellite visibility and signal strength, and customizable filtering tools for focused analysis. Together, these features provide operators with a structured way to monitor, analyze, and document GNSS interference events. SecureTrack is part of SeRo Systems’ broader focus on passive surveillance and spectrum monitoring technologies that support air navigation safety, situational awareness, and regulatory compliance.
