What is this?

This is a personal ADS-B flight tracking site operated by Håkan Dahlström in Malmö, Sweden. It shows aircraft currently visible to a receiver located in Malmö, in real time.

ADS-B (Automatic Dependent Surveillance–Broadcast) is a technology where aircraft continuously broadcast their position, altitude, speed, and identity. Anyone with the right receiver can pick up these signals — no special access required.

What does the live map show?

Each dot on the map represents an aircraft currently being received. Click any dot to see details: flight number, airline, aircraft type, altitude, speed, distance from the receiver, heading, squawk code and signal strength.

Colours indicate altitude — yellow for high altitude (above 9,000 m), cyan for low altitude (below 3,000 m), and green for everything in between. The orange marker in the centre is the receiver location in Malmö.

The map updates every 60 seconds. Flight routes are reconstructed from the last two hours of position history.

What does the statistics page show?

The Statistics page shows aggregated data from the last 30 days: unique aircraft count, top airlines, activity by hour of day, daily aircraft counts, and a coverage map showing the maximum reception range in each direction.

Data is updated every 15 minutes and covers only aircraft received by this station — not all aircraft flying in the region.
