Open, research-grade air traffic data with a live map
The OpenSky Network is a non-profit association that collects ADS-B and Mode S data from volunteer receivers and makes it available for research. Its live map shows current air traffic, and approved researchers can query years of historical data.
It is the standard source for academics studying aviation, emissions or airspace, and its free API powers many hobby projects.
OpenSky Network is especially useful for researchers & analysts and plane & ship spotters.
Yes. OpenSky Network is free to use.
No account is needed to view the map. Signing in unlocks extra features such as saving, alerts or more detail.
OpenSky Network shows data in real time or close to it, so what you see is happening now (most live maps have a delay of a few seconds to a few minutes).
