About
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
Explanation
Altitude colors
The flying altitude of an Aircraft is indicated by its color. Ships are normally blue or grey if moored.
| Color | m | ft |
| 0 | 0 |
| 1+ | 1+ |
| 305+ | 1.000+ |
| 610+ | 2.000+ |
| 915+ | 3.000+ |
| 1373+ | 4.500+ |
| 1.830+ | 6.000+ |
| 2.288+ | 7.500+ |
| 2.745+ | 9.000+ |
| 3.202+ | 10.500+ |
| 3.360+ | 12.000+ |
| 4.117+ | 13.500+ |
| 15.000+ | 49.240+ |
| 25.000+ | 82.067+ |
| 30.000+ | 98.481+ |
| 50.000+ | 164.135+ |
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.
| Color | Type |
| Rescue and Police |
| Military |
| Interesting |
Positions
| 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.

Changelog
Version 4 (19.12.2024)
Over the last 8 years we became more than an ADS-B site by adding AIS in 2021 and radiosondes in 2023. This is why
adsb.chaos-consulting.de is now
sdrmap.org.
ADS-B
- New: Now showing how long ago each station received the last packet from the selected aircraft
- Improvement: More than 200 new pictures of aircrafts
- Improvement: Livetrack now with on hover infos like history track (timestamp, altitude, vertrate )
- Improvement: Now showing true heading of planes on ground
MLAT
- New: Differentiating between stations without MLAT capability (red) and those that do support mlat but are not used for position calculation of this aircraft at the moment (grey)
- Improvement: Fixed MLAT mesh links
AIS
- New: Now showing how long ago each station received the last packet from the selected ship
- Improvement: Better handling of invalid positions transmitted by atons
Radiosondes
- New: Radiosonde uptime and killtimer for some types
- New: Radiosonde battery voltage gauge now scaled accordingly to different sonde types
- New: Introducing radiosondes minumum, average and maximum hoizontal and vertical speed
- New: Now showing how long ago each station received the last packet from the selected radiosonde

- New: GeoJSON archive of all revious flights (can be recalled and visualized on map)
- New: Launchsites are now shown on the map
- New: List of launchsites in the sidebar (Including number of active sondes and time until the next scheduled launch)
- New: Launchsite infocard in the Sidebar (Including info on operator, frequencies, active sondes, recent launches and predictions)
- Improvement: Correct colors according to type in radiosonde list
- Improvement: Correct matching of Radiosondes to Launchsite
Stations
- New: Minimum, average and maximum range and SNR for radiosondes
- New: Hiding empty tables (top10 and MLAT sync peers)
- New: Graphing for minimum, average and maximum range and signal strenght for ADS-B, AIS and Radiosondes
- New: Now showing distance of MLAT sync peers
- New: Color coded sync peers according to sync quality/usability
- Improvement: Fixed inconsistent fields in station list
- Improvement: Chart rendering
- Improvement: Fixed rendering of system performance gauges for offline stations
Filters
- Improvement: Fixed broken "Nav Modes" filter
- Improvement: Altitude filter is a slider now with lower and upper limit and increased range to accomodate radiosondes
Repo
