"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".
Comments
Veikko: Yes, see https://www.youtube.com/watch?v=CThfM9tPKGM for an example of someone decoding AIS.
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.
No idea. The RTL-SDR can be tuned to 978 MHz, but I don't know of any available UAT decoding software.
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!
there was a discussion of this idea a little while back..

Or even to sense and put a dummy transmitter on a collision course, you don't even need a real collision.
Surely this sense and avoid could easily be subverted to sense and collide?
Yep, very nice.
Can't wait for USB host on Arducopter.
