Found and article today that led me to this website that answers some problems with GPS and Drone use around sensitive area.

This is really a matter for security organisations, not surveyors.
Surveyors should be concentrating on the legal use and advantages of technology solutions available. After all, ranging rods can be pretty effective offensive weapons but we don't spend our time looking for ways to remove them from use.
Any licensed operator would be speaking to nearby establishments which might have such anti-drone equipment before flying, so that the survey activities were clearly understood. In my experience airports and airfields are only too pleased that the surveyor has contacted them and outlined the work being undertaken ( and ALWAYS let them know when you have finished for the day). On one occasion we even had a control tower hold a helicopter on the ground for 10 minutes until our survey was finished.
Those things are only available to law enforcement and other Governmental law agencies.?ÿ
