So, rather than drop from the sky, according to the video (which they say is faked, but still is a realistic demo) it looks like the drone slowly descends while the “shooter” maintains their sight on the drone.
To me, it looks more like this “gun” is jamming the drone and forcing it into its failsafe mode, which makes it descend and land in a safe way. Quote from dronezone related to this:
Failsafe works differently depending on the mode the Phantom is in. When Failsafe mode is initiated whether it is in the Ready to Fly or Ready to Fly (non-GPS) mode.
Ready to Fly (non-GPS) – Automatic landing: The flight control system will try to keep the aircraft level during descent and landing. Note that the aircraft may be drifting during the descent and landing process.
Ready to Fly – Automatic go home and land: The flight control system will automatically control the aircraft to fly back to the home point and land.
Does this mean that this jammer only works on drones without GPS?
