I got dump1090 up and running on a Kali laptop and took it on the road today. Everything seemed to work fine, but not every plane was tracked. I'm not sure why. I parked in easy view of the airspace over a huge international airport and started scanning with the dongle antenna roof-mounted.
At max count I only had 11 aircraft on screen, yet I could easily count many more that in the sky just using my eyes.
I am a beginner at this, so I am sure there is something I am missing. Do all airlines use the same protocol or are there competing systems and this software only decodes one version or something?
Either way it's cool, and fascinating to watch. See a plane in the sky and know just what it is and where it's going, etc.
BTW, thank you for this thread and the helpful tips on dependencies :) Made it a breeze to install on Kali.
