We are an European group of people interested in the observation of local and international air traffic. Whether out of interest in (radio) technology, development of hardware and software, or simply in unfiltered air traffic: Every antenna in the network matters ‒ especially to improve coverage at low altitudes! Through an extensive network of receiving stations, everyone contributes their part to the information variety. If you already operate your own ADS-B receiver or require advice in selecting the best hardware for your location, contact us.
