Free 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 350 billion ADS-B and Mode S messages collected so far, the OpenSky Network exhibits the largest air traffic surveillance dataset of its kind.
