We are currently beta testing MLAT (Multilateration). By having 4 or more FR24 receivers covering the same area we can calculate positions of aircraft without ADS-B. Today we have some MLAT coverage in Sweden, Denmark and Poland, so we are now looking for more potential hosts for our FR24 receiver. If you live in Germany, UK, Denmark, Czech Republic or southern Norway and want to host a FR24 receiver, please apply on http://www.flightradar24.com/free-ads-b-equipment
MLAT on FR24 is still in beta test, so it's only available for all our premium users.
You can read about MLAT on http://www.multilateration.com/surveill ... ation.html

Es wird ausdrücklich nach Bremern gesucht.
Leider kann ich die externe Antenne nirgendwo platzieren, sonst würde ich mich selber bewerben.
