It is like a volunteering your position by self-reporting it. ADS-B is very cool but the moment you turn it OFF you disappear from the sky. Here you can see NOT just planes you can see anything that has an RF reflective paint and happens to fly. It is intended to be received by aircraft equipped with Mode-C receiver and plot it “like a real” radar.
Mode-C is a broadcast by the ground stations back up in the air with the full mixed data from primary and secondary. Now what I still wait is for someone to come up with a cheap mode-C receiver. So even if one was to come up with a squawk listening device that would be useless for lateral plots. Only the squawk part is readable since it is primitive yet digital data. I have to dial the knobs next time to see where each digit stops – pretty sure it stops at 7 or 6. On top of that the possible squawk codes are less than 9999.
The pressure is converted into altitude and combined with the primary echo to plot what one sees on TV as the controller scope image. The 1960 design (that’s what we use today) transponder only sends out barometric pressure (called the secondary return) and 4 digit squawk NOT altitude and that alone is absolutely non contributory data to the lateral information, which is collected by the “primary” return which is the 1920s technology of simple directional echo measurement.

With a USB TV tuner and a Raspberry Pi, is able read the tail numbers, altitude, latitude, longitude, speed, heading, and even the type of aircraft currently flying over his house. This program allows to attach his SDR to a Raspbery Pi and put it somewhere the antenna will get good reception – an attic, or an outdoor weatherproof case – and stream data to his desktop over a WiFi or network connection. is using a Raspi and RTLSDR TV tuner to listen in on aircraft transponders, and getting a whole bunch of data from aircraft flying overhead.Įven though the ADS-B decoder is using is written for OS X, he’s reading the data coming from the USB TV tuner over the network with a program called Dump1090. This year, it’s all about the Raspberry Pi, so it’s surprising we’re only just now seeing a mashup of these two pieces of hardware. Last year’s big hack was software-defined radio a small USB TV tuner that could listen in on radio broadcasts anywhere between MHz.
