About the OpenSky Network

The OpenSky Network is a community-based receiver network which has been continuously collecting air traffic surveillance data since 2013. Unlike other networks, OpenSky keeps the collected raw data forever and makes it accessible to academic and institutional researchers. With over 15 trillion ADS-B, Mode S and FLARM messages collected from more than 2000 sensors around the world, the OpenSky Network exhibits the largest air traffic surveillance dataset of its kind.
