ADSB for mission planner just using an SDR dongle

Mission planner has had ADSB in for a long time now, but getting an ADSB source has usually been either complicated or expensive requiring a lot of extra hardware like a pi or special receiver to do the ADSB decoding and send it to mission planner via mavlink but by running a simple program and connecting mission planner to it, we can get ADSB working in a few steps.

First get a supported SDR dongle, you dont need a specific one for ADSB, but there are specialised versions with better filtering specifically for that frequency that will get you much better detection range, I am not going that far, so im just getting the smallest one i can get

I did the docker version some time ago. Their wiki got a lot of good information about antenna and tuning : Learning ADS-B Technology: A DIY Guide

About range, with the adsbexchange key and a 3db antenna, I got about 200km from my home roof !

I done this about 8 years ago using a program call adsb#, but thats not available anymore and its functionality is now part of airspy software that you need to pay for.

I found rtl1090 when I went looking for an alternative, it’s basically the same as the adsb# program, an onboard adsb receiver would be nice but I haven’t found a way of doing it cheap.

@geofrancis, thanks for the detailed write up!
