RadarBox is a a success in Brazil, especially because of network feature where, in such a big country, users are able to track flighst in real-time all over it (using the real-time sharing provided by RadarBox network).
The user base is constantly growing there and we already have major cities covered. This includes Sao Paulo, Rio de Janeiro, Recife and Fortaleza. Users in Sao Paulo are able to track flights flying to Guarulhos more than 4 hours before landing, as they enter Brazilian airspace closed to Fortaleza or Recife.
Our users in Brazil decided to create an user group solely dedicated to RadarBox.
