What is OpenSky Network?
The OpenSky Network is an open-source, crowdsourced community building a large network of sensors across the globe to monitor aircraft traffic in real-time. Volunteers build low-cost ADS-B receivers using software-defined radios like RTL-SDR USB sticks to track aircraft location, altitude, velocity, and identity information.
The open data is used by hobbyists to visualize flight paths, by researchers and academics to study air transportation systems, and by companies to provide enhanced services. Anyone can view location data via OpenSky's live flight tracking web map and access historical data through their free API.
As an open-source project relying on community contributions, OpenSky aims to promote transparency, enable innovation, and increase public knowledge around aviation. With over 2000 sensors across more than 100 countries, the network provides unique global air traffic surveillance independent from government control.
