A proposal for 3G control

3689504133?profile=originalSo,

I recently posted in a forum about how to add 3G uplink to a UAV model.  This project seems really fun to me, so I'm thinking about writing the software to make it happen (a little web server and some new features for Andropilot).  

However, the bummer is that some uses wouldn't be legal in the USA (given the current harsh FAA interpretation we need to operate under - <400 ft, visual range of control).  

To make sure this app/feature was used 'correctly', I would have it check to see if you are in a 'long range control is legal' country.  If not legal, I'd have it automatically send a mavlink RTL command if you got more than x (1?) km away from the home location.  

My question:

  • Are there countries where unrestricted long range control are legal?
  • If you are in such a country, are you willing to put a (cheap) android phone into your plane and give this a shot?  If you are, I'd probably be willing to make the software/servers go.

  • Happy to participate, no such limitation here in Australia
  • The feature that I think would be the most useful.............:)

  • Ok I am anxiously waiting! I am sick of dealing with all the trouble caused by my FPV gear, antennas, wires, tx's, rx's, etc. It's a real pain. I really with you would incorporate a stream with OSD overlay. I know latency is a problem here to replace FPV, but I don't really need that. I usually fly in auto mode. I think it would even be somewhat ok in stabilize mode too, as long as you aren't close to the ground or anything.

    Thanks so much for your work! I envy coders, someday i'll learn...

    Yes - www.droneshare.com, but it will be a few weeks before I have bidirectional control via 3g working...

  • Any work on this project? Im really interested in this. 

  • Time to bring our babys up in the air ...

  • Hey Kevin, I have a webserver I would like you or anyone else that will strap an android device on a plane to try. just message me!

  • Charles.

    Thank you for pointing that out.  I was honestly getting sick of people touting that as the law, however with the new FAA changes I think we might see some changes.

  • I am also interested in this project for now I have no restrictions, I would be willing to test it.

  • Like it. Andropilot is really fine, but could think about a version, which could connect to Mission Planner and/or QGroundControl as well. Both are running MavLink (TCP and/or UDP). Doing this myself, i had some problems in the past with power-levels (android-phone V+ and apm/battery V+).

    a) USB-Host (power level concerns, but maybe we could power the control part of the APM with battery of the (telemetry)phone over the USB-Host connection?)

    b) serial-USB. SerialUSB i don't know, if we could only use 3 Pins of the 4 Pins Uart-telemetry port (Ground, TX, RX) in a dual powered setup to avoid power-level troubles. If somebody has more knowledge, this could help a lot.
    c) Bluetooth (saver and easier, but strange to set up an air-connection just for 5cm)
