How to Build an Airplane Tracker with Raspberry Pi

Chances are that there are planes flying over your house right now. Using a Raspberry Pi, a device known as an ADS-B receiver, and a standard projector, we can create our very own “radar” that shows the real time location of these aircraft and, if we have a projector, we can project it on the ceiling. Otherwise, we can track it on a regular screen. 

About ADS-B Technology

Lots of aircraft are outfitted with a device known as an ADS-B. Standing for “Automatic Dependant Surveillance-Broadcast”, it’s a technology that allows aircraft to transmit positional information about themselves to other aircraft, ground-based stations, and even satellite-based stations. For smaller planes where it isn’t feasible to install more complicated collision-avoidance technologies, an ADS-B transmitter and receiver can do a lot to increase flight safety.
