UAS Toolbox groups recent ADS-B navigation-accuracy observations into global hexagons and shows the proportion of aircraft reporting degraded accuracy. The map can reveal patterns that correlate with GPS jamming or spoofing across GPS, Galileo, GLONASS or BeiDou use, but it cannot prove the cause or guarantee conditions for a drone at ground level.
What the feature does
How it is used
- Search or select a location
Move the global map or search for the planned flight location.
- Review level and confidence
Compare the adjusted degraded-accuracy percentage with the number of reporting aircraft.
- Use layered verification
Combine the GNSS indicator with local observations, NOTAMs, equipment checks and official interference information.
Limitations and sources
- The map is an indirect ADS-B indicator, not a spectrum measurement or proof of deliberate jamming.
- Aircraft altitude and receiver conditions can differ substantially from a drone operating near the ground.
- No data means insufficient observations, not confirmed low interference.
Frequently asked questions
Is this a real-time GPS jamming detector?
No. It is a recent, ADS-B-based interference indicator. It visualizes aircraft-reported navigation accuracy and cannot identify the transmitter or prove jamming.
Which satellite systems are covered?
ADS-B messages can derive position from multiple GNSS constellations, including GPS, Galileo, GLONASS and BeiDou. The source does not reliably identify which constellation caused an individual degraded report.
Why can an area show no data?
The method depends on suitable aircraft observations. Sparse traffic, receiver coverage and filtering can leave a cell without enough data, which must not be interpreted as low risk.
