I would like to set one of these up. Is there an extensive guide that explains where to put the sensor, how to setup the pi, etc?
I've been using a Pi for a while to track ADS-B and AIS. If you haven't purchased the hardware yet head over to https://www.nooelec.com/store/ to get the SDR dongles. And then grab the latest Dump1090 https://github.com/antirez/dump1090
As for guides. It's a pretty big community so just use the keywords from above [RTL-SDR, ADSB, DUMP1090] and you should get a lot of guides on tracking aircraft.
