About us

  • We are a bunch of hobbyists containing of aviation enthusiasts, ham radio operators, ...
  • We are interested in everything moving no matter if it is planes, ships, trains or satellites
  • We build our own aircraft, ship and radiosonde tracking network

About our network

  • We are noncommercial
  • We develop our own application and continue to modify it to our liking
  • We are very focused on the feeder stations and we do have a lot of features geared towards them

Getting started

  • Check out our wiki to learn more about building an ADS-B, AIS and radiosonde receiver station
  • If you already have a station you can start feeding today

Altitude colors

The flying altitude of an Aircraft is indicated by its color. Ships are normally blue or grey if moored.


Type colors

Special vehicles like rescue ships or aircrafts or military vehicles are color coded. Other special vehicles like pilot boats are marked as interesting.
These colors are used on the vehicles on the map as well as in the lists in the sidebar. The altitude of this vehicle is not indicated in the vehicles color but in the color of the vehicles track.

Rescue and Police


This position is transmitted by the vehicle
This position is calculated via MLAT as the aircraft does not transmit its position
This vehicle has no position

Multilateration (MLAT)

If an aircraft does not transmit its position via ADS-B but does send its ICAO code there is the option to calculate the aircrafts position via MLAT. To be able to do this there are at least 3 receiver stations needed which are MLAT enabled, do receive the planes messages at a decent signal level and are in sync with each other. The more stations are involved in the calculation the more accurate it gets. If you do have a station make sure to enable MLAT.

Open Data

No matter if map tiles and weather data or gerneral aviation knowledge we would not be able to do what we are doing without the following services.


All map data https://www.openstreetmap.org/copyright


Sea map data https://openseamap.org

Deutscher Wetterdienst / PegelOnline

The precipitation data, weather warnings and water levels of German rivers and coasts are taken from the great Open Data Services by Deutscher Wetterdienst and Wasserstra├čen- und Schifffahrtsverwaltung des Bundes


All the knowledge about airlines and planes https://de.wikipedia.org

junzis Aircraft Database

Aircraft registrations and model information are based on the last release of junzis Aircraft DB (MIT License), regulary updated by us with own observations and research.

Source code

As this website is open source you can have a look at the source code. You will find it right here: https://github.com/chaos-consulting/adsb2.0 If you experience a bug let us now. If you have an idea for improvement just talk to us, we will look at it but can nt make any promises as development takes place in our spare time.
