Don’t they switch to autopilot when they lose communication. And how protected are they from jamming and noise? Seems like all of this would have been considered in the design.
However, there are probably different levels of complexity and cost. Cheap low end drones have no protection. Expensive high end drones have lots of protection plus other techie advantages.
Newer models are programmed to return to base upon loss of communication.
Thus, this technology is rendered moot.
Years ago I worked on a paper for the DHS regarding pipeline cyber security. The phrase that stuck with me was “if you mandate a 12-foot fence somebody’s just gonna bring a 13 foot ladder”.
It was on that day I gave up.
