Building A Long Range UAV

I am working on a project of controlling a UAV over long ranges, for example would it be possible to control a UAV Via wifi?. 2.4ghz has a range of 140 mile with the proper equipment, so would it be…Continue

I have the PC/Tx interface which I purchased for FPV flight, not for UAVs.

Doc,
As others have hinted (or plainly stated) this is a big project. One suggestion is to decide whether you have a real reason to use 2.4 GHz, or is it that just you heard about someone's sister's boyfriend's cousin achieved 140…

Found it. Yes, for unlicensed operation, if you use a directional antenna you have to reduce 1dB for each 3dB.
Permissible under Part 15: Max. Transmitter RF power Ant. gain (dBi) EIRP (W)
2.4 GHz omni-directional 30 dBm (1 W) 6 3.98
2.4 GHz…

I was not confused.
After the joke I mentioned *another* way of achieving the range *without* using huge power.

this is where you can find the interface to control a uav with a joystick

@Docmafia,
Are you talking about UAV, or FPV, or R/C?
You would not be controlling a UAV with a joystick... that sounds like FPV or just plain R/C.
There are many forum threads here dealing with increasing the range of the many radios which need…

Mr mafia try this link, I'm sure you will find it interesting

You might want to check your local regulations and laws before expending too much effort on this - in the UK, UAVs must remain within 500m of their operator, and I believe the US rule is similar. You can get around this by applying for various…

Thank you all for your input, I think I am going to have to study on radio waves and transmission or hire someone here locally to help with this project.

You can expect some 20km from 800MHz region modems and 9600baud.
There is whole rcgroups discussion on that.

Don't confuse EIRP with actual power. You cannot cook a chicken with one watt regardless of antenna gain. The beam would have to be focused on a very small spot on the chicken to produce significant heating. With a dish the beam is never that…

If the base station was at 10 feet, the UAV would need to be above 10,000 feet.

Two possibilities:
Get a 3g cellular aircard (e.g. Verizon EvDO) and do everything over IP or get a Technician Amateur radio license (assuming you are in the US).
The power for a remote control link under amateur radio rules is limited to 1W (no…

You can use the Iridium sat phone system, it is use by the US force to control the Global Hawk UAVs over the Arctic region.

Just for interest, how high would the UAV have to be to still be in radio LOS at 140 miles??
