However this transmissions happen in the 1090 Mhz frequency. I use "modes_rx" that is free software, just Google for it. With software defined radio there are a lot of programs in order to demodulate this information (that is encoded in a fairly simple to decode format). Every aircraft broadcasts informations about heading, speed, altitude and so forth. Basically ADS-B is a security device that is installed in most aircrafts that is used for collision avoidance and other stuff like this. ![]() My Sunday goal was to use the RTLSDR to see if I was able to capture some ADS-B message from the aircrafts lading or leaving from the airport. It's really a lot of fun, for instance from my home that is at about 10 km from the Catania Airport I can listen the tower talking with the aircrafts in the 118.700 Mhz frequency with AM modulation, however because of lack of time I was not able to explore this further until the past Sunday. # Software defined radio is coolĪbout one week ago I received my RTLSDR dongle, entering the already copious crew of software defined radio enthusiasts.
