The (OGN) is a community-driven project collecting tracking data from -equipped aircraft. The channel is available to everybody and activated by default, no action required on your side for receiving their data, but see below for tips on aircraft types and models.
OGN brings gliders and other light aircraft to LiveTraffic. You can find yourself amid groups of soaring gliders during a good weather weekend, or watch tow planes busy at work. Don't believe it? .
FLARM receives and the OGN network is most popular in central Europe, especially Switzerland, Germany, Austria, UK, and some countries around that. A few hotspots can be found at times also in other parts of the world, at the time of coding especially near Toronto, Canada.
Check out to see current coverage and don't hesitate to zoom out to a world view. Two note though:
live.glidernet.org shows anonymous planes (hidden identity) with ids having a leading underscore _, in LiveTraffic they appear with a different id with a leading question mark. They cannot be matched...by principle of a hidden identity. See for more.
live.glidernet.org tends to show icons also some time after the respective device was switched off already, while LiveTraffic only shows live devices, so you might see a little less planes in LiveTraffic. In case of doubt click on any symbol in live.glidernet.org and compare Last Time to your current local time:
We need to talk about aircraft types for two reasons:
Here are some recommendations of CSL models you may want to install.
To activate/deactive Open Glider Network just place/remove the checkmark next to Settings > Input Channels > Open Glider Network (screenshot below).
LiveTraffic downloads an aircraft database from OGN to look up exact model information. That is the OGNAircraft.lst file appearing in your LiveTraffic/Resources folder.
But if the actual aircraft is not listed there then its exact model is not known, but only one of 15 generic FLARM plane types as transmitted by OGN. In LiveTraffic's settings you can assign ICAO type codes for them so that LiveTraffic can pick a model. You can even name several ICAO types, separated by space; LiveTraffic will pick one of them randomly then each time it needs a type code.
OGN tracks aircraft with 3 different kind of ids: ICAO, FLARM, and OGN. The column "Key Type" in the Aircraft List can tell you.
You may want to install , or even balloons and airships, as these are the types of planes most often seen in the OGN data feed.
Depending on 1. you may want to amend the models used for , which are used if the exact model of an actual plane is not known.
Individual CSL models (see how to install):
(ICAO type AS21)
X-CSL models (see how to install):
(package delivers generic ICAO type code "GLID", though "DUOD" would be correct)
(generic ICAO type code "ULAC")
The [Live Glidernet] link opens a browser for you on , centered on the location you are right now in X-Plane. The same link appears on the .
The last checkbox in the Open Glider Network settings, Use alternate connection, activates an alternative technical connection to the Open Glider Network, in which LiveTraffic requests current positions periodically, the same way as it does for and . This is also automatically used as a fallback in case the primary push-type connection fails. See for more if interested.
Anonymous planes: If ID/Call Sign start with a question mark then the aircraft owner has asked to hide his/her identity. The plane can be tracked but no details must be published. LiveTraffic shows a generated key, id, and call sign. certainly does the same. In their case the displayed id starts with an underscore _. By principle, as identifying information is hidden, LiveTraffic cannot reproduce the same id that live.glidernet.org shows. That makes it a bit difficult to match those planes between LiveTraffic and live.glidernet.org.
By default, LiveTraffic uses a push-type connection: It connects to an APRS server and OGN pushes position updates to LiveTraffic as soon as available. That allows for very precise tracking, which makes it possible to closely follow the tight turns of soaring gliders and paragliders. A starting point for understanding how to subscribe to such data and what the format looks like is .
An alternate connection is available as a fallback (or via ): This is a request/reply-type of connection, in which LiveTraffic sends a standard HTTP-GET request to the server, that also feeds the radar web site. This procotol is not officially standardized and therefor subject to change. Find some information about it.
To be able to look up aircraft model information, LiveTraffic downloads OGN's plane database, stores it as Resources/OGNAircraft.lst and refreshes it every 12 hours. This is the same database as can be searched .
