Almost all the aircraft flying overhead broadcast tracking information on 1.09GHz via ADS-B. ADS-B is an open protocol. So what? Well, it means you can decode it. If you just interested in what information this RasPI set up can provide to you take a look at the pics below. Keep reading if you are interested in duplicating the rig.
The two graphs below show how many aircraft were tracked and how many positions were reported to FlightAware.com (more on this later):
…Still interested? Setting it up is pretty easy now thanks to satsignal and FlightAware.com; check out these sites if you want more detail or have a problem. Anyone should be able to duplicate the build. When I first took the project on things were not quite as straightforward; it was even kinda difficult…. It is now straightforward this blog entry has been edited down to just a few lines and some tips. Seems like a lot of commands, but copy/paste makes will make the install fast. Most of the info on this page comes from the two sites mentioned above so look there is you want details.
