How to Track Government Aircraft 200 Miles Away with a Raspberry Pi

Aircraft equipped with ADS-B are constantly shouting their location into the radio void, along with other useful unauthenticated and unencrypted data. In this guide, we will make an ADS-B receiver using a Raspberry Pi with a software-defined radio (SDR) dongle, which we can use to track aircraft anywhere in real time. In my last article, I covered how to track flights using publically sourced radio receiver data on your phone. However, using public source data has some limitations, like blocking some interesting private jets and government aircraft or lack of coverage at lower altitudes. Now... more
