It would have been fun to attempt to jam the RPV’s control signal. Would rapidly make it apparent how robust the signal is and whether there were autonomous piloting capabilities. Probably uses both advanced digitized frequency skipping and spread spectrum along with autonomous recovery capability, at least in the military versions.
It is possible it is controlled from satellite, but I doubt this domestic version is.
Depending on the UAV, it either continues its preplanned route or goes to command lost state. The latter tends to be climb and cirlce until the link is re established. Note that the current command frequencies are not authroized for police use in this country.
This is showboating. Other attempts to do this by police have been rightly “shot down” by the FAA.
