Re: Countdown ..
"When hardening drone electronics, you do run into the problem that drones are usually radio-controlled. Hardening the antenna is basically impossible.
If you have an uncontrolled drone it becomes a lot less threatening."
It wouldn't be too hard to put up a drone that runs a programmed path and fetches back the video. If the video shows there isn't one of this types of units deployed, they can pop up other drones that are constantly communicating with the operator. Super cheap drones that rise up and communicate down to a limited footprint would eliminate the usefulness of this. That drone's problem is that it can show the operator's location, but if that's already known it doesn't matter.
Without much time I can think of a few different ways of defeating this unit for small observation drones. For bigger drones such as a reaper or Global Hawk (World Chicken), it get harder.
Yes, GPS receivers must have an antenna, but if the drone isn't radiating, the zapper is robbed of a way to find and track.
