“Stealth” Drones. How can a drone be “stealthy” if it must be constantly transmitting data in order to be remotely operated? Isn’t radio silence a requirement for stealth in the modern battlefield?
I don’t know if this is done, but another idea could be to use light. There is no way to sniff that. But with the resolution of current gen keyhole satellites and a stealth drone with known flight path a light signal could be used to morse code some information back.
