Open Air Traffic Tracking Data

The OpenSky Network is a community-based receiver network which continuously collects air traffic surveillance data. Unlike other networks, OpenSky keeps the collected data forever and makes it available to researchers. With more than 2 trillion ADS-B and Mode S messages collected so far, the OpenSky Network exhibits the largest air traffic surveillance dataset of its kind.
