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.
Contribute to independent aviation research with your data! Connect your ADS-B receiver to the OpenSky Network or host one of ours.
