skies-adsb is a virtual plane spotting progressive web app / virtual aquarium (with aircraft instead of fish) / interactive real-time simulation. Aircraft are tracked via unfiltered ADS-B transponder data in real-time and rendered in 3D. The ADS-B data source is meant to be a RTL-SDR receiver connected to a Raspberry Pi running on your home network. Flight status data is provided by the FlightAware AeroAPI v2. The aircraft photos are provided by Planespotters.net.
