Introducing Interference Analytics for GPSwise
We’ve added a new paid add-on to GPSwise: Interference Analytics.
Its goal is simple: help you understand when and where GNSS spoofing and jamming events occur, and what they mean for flights within a given airspace or fleet.
Interference Analytics is an interactive dashboard where users can:
- Explore interference events visually
- Download plots
- Export occurrence tables to CSV with a single click
Use Case 1: Monitoring GPS Spoofing in a Specific Area
Air Navigation Service Providers (ANSPs), Civil Aviation Authorities (CAAs), and spectrum monitoring agencies can investigate spoofing events in detail.
Example: June 30, 2025 — Mexico FIR (MMFR)
On June 30, 2025, GPSwise detected 10 spoofed flights in the Mexico Flight Information Region (FIR).
To analyze this event:
- Open the Interference Analytics dashboard
- Search for FIR: MMFR
- Select the relevant date or time range

What You See
The results include:
- Map — showing the positions of flights impacted by GPS interference
- Frequency Analysis — visualizing occurrences hourly, daily, or weekly
- Flight Table — listing all affected flights with detailed information
Key Insights from the Event
The data shows that:
- The impacted area was around Monterrey, Mexico
- Spoofed positions were near Aeropuerto AFL Parque Industrial Mitras
From the frequency analysis:
- First spoofed flight: 17:00 UTC
- Peak activity: 18:00 UTC (6 flights in one hour)
- Last detected event: 20:00 UTC
Flight-Level Analysis
Users can select any flight to:
- View its trajectory
- Replay the event
For example, flight VTM356 shows a clear spoofing signature:
- Sudden position jump from Saltillo to Monterrey
- Return to the correct trajectory shortly after
Use Case 2: Monitoring a Fleet
Airlines can use Interference Analytics to track spoofing and jamming incidents affecting their fleet.
Search can be performed using:
- Callsign prefixes
- ICAO24 hex identifiers
Example: Aeroflot Fleet Monitoring
By searching using the AFL callsign prefix, users can analyze Aeroflot flights over the past 7 days.
What You See
- Map — showing where aircraft were impacted
- Frequency Analysis — revealing that approximately 150–200 flights per day experienced spoofing
Each occurrence can be further investigated using ADS-B trajectory analysis.
Summary
Interference Analytics combines multiple capabilities into one tool:
- Geographical monitoring for ANSPs, CAAs, and intelligence agencies
- Fleet-wide monitoring for airlines and operators
- Frequency analysis to identify patterns and peak activity
- Flight-by-flight investigation with trajectory replay
It is designed as a practical tool for both:
- Investigating past incidents
- Monitoring ongoing interference activity
