UAS Toolbox

Global GNSS interference map for flight planning

The global map visualizes aircraft-reported navigation accuracy as an indicator of possible GNSS interference and shares the local result with the dashboard GPS status.

Open the global GNSS map

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

Worldwide hex map

Pan across the world, choose a date and inspect areas where aircraft reported lower navigation accuracy.

Confidence-aware status

Each local result includes the aircraft count and a confidence level so sparse data is not presented as certain risk.

Shared dashboard indicator

The selected dashboard location uses the same GNSS status logic in the GPS ± metric, keeping weather and map planning consistent.

Transparent methodology

The interface identifies the upstream dataset, observation date, adjusted percentage and important interpretation limits.

How it is used

  1. Search or select a location

    Move the global map or search for the planned flight location.

  2. Review level and confidence

    Compare the adjusted degraded-accuracy percentage with the number of reporting aircraft.

  3. 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.
