Mission

GPS interference is frequently reported in the airspace from the Eastern Mediterranean to the Black Sea. Yet who is affected, where and by how much often stays anecdotal.

Our goal is to make the phenomenon measurable, repeatable and explainable: every colour is an observation backed by a list of aircraft; an indicator, not a determination.

Principles

Explainability: we show why a cell has its colour and what each aircraft reported.

Honest coverage: missing data never looks 'clean'; cells with few aircraft are not coloured.

Method framework: what is measured, what it means and the limitations are described in outline on the methodology page; the detailed calculation rules are not disclosed.

Privacy: aircraft identifiers are shown at observation level only; we collect no personal data.

Data sources

The main source is the adsb.lol community network (ODbL licence). Region/FIR names come from EUROCONTROL Network Manager data.

See the Data and licence page for details on sources, licences and attribution.

What we are not

Manzlytics is not an operational navigation or safety source. Rely on official NOTAMs and bulletins for flight decisions.
