OK, what is an FSD? It is a Field Strength Drone. It’s an idea I am sure others 
have had, and I don’t expect to get around to designing or patenting such a 
thing. But inventions are often just the merging of new technologies, and this 
is not much different. I don’t see any YouTubes about this or any other 
reference, so here’s the idea:

With all the capabilities of little drones I wonder if anyone has designed one 
which can carry a field strength meter and fly a grid around an antenna to 
evaluate antenna performance. The guts of my little Radio Shack FSM would have 
weighed way less than an ounce.

Ideally, the field strength meter could communicate to the base through the 
drone transmitter, reducing weight. Software at the base could link the drone 
3D location data with the FS reading. The drone would have to wait at test 
locations for the operator to transmit, and ideally would move to the next 
location. Finally, the software might be able to link with existing simulation 
software for comparison with theory and allow for simulation model improvement. 
This looks like it would take a small team to develop.

This sounds like it would have many uses besides antenna evaluation, like RFI 
evaluation.

What about it? Has anyone done this?
