PocketCHIP is perfect for taking out in the field with it’s integrated keyboard, touchscreen and battery, so what better use for it than to decode ADS-B beacons from aircraft as they pass over your head?
Assuming you’ve got as far as connecting to wi-fi and you have a RTL-SDR dongle handy,
Make sure you’ve got up-to-date package index, and run updates for good measure
sudo apt-get update
sudo apt-get upgrade
Install git and then clone antirez’s repo
sudo apt-get install git
git clone https://github.com/antirez/dump1090
Move into the directory you just cloned
Install the dependancies required to build dump1090, then build
sudo apt-get install gcc make librtlsdr0 rtl-sdr librtlsdr-dev pkg-config libusb-dev libusb-1.0–0-dev
Test. If you don’t see anything check your antenna connection and then Flightradar24 and make sure there are planes around.
./dump1090 —-interactive (for terminal output)
./dump1090 —-net (for map output viewable in a web browser)
Once you’re happy you’ve got it working right, get out and ideally up high with as few obstructions to the horizon as possible and do some plane spotting!
