The OpenSky Network is a community-based receiver network which continuously collects air traffic surveillance data. Unlike other systems, OpenSky keeps the collected data forever and makes it available to researchers from different fields. With more than 100 billion ADS-B and Mode S messages collected so far, the OpenSky Network exhibits the largest air traffic surveillance dataset of its kind in the world.
Join the network, help researchers!
Contribute to independent aviation research with your data! Connect your ADS-B receiver to the OpenSky Network or host one of ours.
