"Cheap ADS-B on Amateur Drones":
Get a head start on the NASA Centennial Challenge's ADS-B requirements by plugging a $20 USB dongle into your drone and tracking nearby aircraft:
- Start with an AR.Drone (or other ARM-based amateur drone).
- Buy a $30 USB dongle. See the rtl-sdr wiki for recommendations.
- Compile and install the dump1090 Mode S/ADS-B decoder software with my easy-to-use cross-compiler setup: ardrone-dump1090-cross-compiler
- Plug in the receiver.
And now you're decoding packets:
ADS-B sense-and-avoid is seen as critical to integrating unmanned aircraft into the National Air Space, and this is the beginning of a cheap "sense" solution. Next up: "avoid".

Veikko: Yes, see https://www.youtube.com/watch?v=CThfM9tPKGM for an example of someone decoding AIS.
Most of things in this life can be subverted but that should not make us miss good things :)
I had Kinetic-Avionic SBS-1 for some time and had fun but gave it away :((. Now searching for the dongle that can do this :(=)
Well done!
Nice! congrats.
Ahem lets not forget 30 quads flying 1000' below one of the busiest approach paths in the world at night in London just last week. DSA is a bit of an FAA red herring. Lots of useful work could be happening in the USA within VLOS.
A key technology that will need to be incorporated for safe integration of unmanned flight.
No idea. The RTL-SDR can be tuned to 978 MHz, but I don't know of any available UAT decoding software.
Are you sure this would fulfill the nasa requirements. Most GA planes don't transmit this data and all planes are moving to UAT I think? It seems like this only supports the 1090MHz mode-s stuff...
Lloyd: Yes. Just change the sign on your error function... More seriously, maybe it's time to add security to ADS-B, though it's not obvious to me how to do that and still have it be useful.
Richard: Thanks for the link, I had missed that.
Kevin: I was toying with the idea, but I'm completely unfamiliar with the PX4 code, so I say, go for it!
Super cool! John - are you planning on PX4motizing/adding to aruplane? If not, I could help out with that... I Already have the sw modem.
