I am guessing that this messes with the GPS the drone uses to navigate. So if the "drone" does not rely on GPS then this thing will have no effect on it. It will work great against off the shelf units but I would imagine someone who is using one for evil will fly it with out GPS.

It does two things, from what I'm reading. Messes with the GPS signal and messes with the control link from the transmitter. This covers both autonomous and remote controlled units.

Modern R/C radio systems have a "fail-safe" mode. If they lose the signal to the transmitter signal, the fail-safe can be programmed to do certain things (depending on the type of craft). For R/C Helicopters it could be programmed to stay in hover or auto-land until it re-acquires the transmitter.

For R/C planes, you usually program the fail-safe to do slow lazy turns.

For R/C cars, it usually cuts the engine.

I would imagine on drones they're either set to hover or land unless it's sophisticated enough to have some kind of inertial navigator that could fly it back to it's launch point.

Less recoil that a 10 bore goose gun too!

Right. If its flying autonomously using gyros and machine vision then this will do nothing.

Yeah. However, most consumer drones aren't autonomous. I'd say the main purpose for this is to put a consumer drone into fail-safe. The people I can see using them is law enforcement, firefighters, airport security, etc.

Yeah they have a product for a future problem that may or may not happen.
