This is not strictly electronics, but anyway.
I want to make a device that would allow an autonomous drone to land inside some specific area, hopefully in bad weather as well as nice weather, and should be used for the final approach only.
Since time of flight systems will be quite susceptible to wind, I want to try make something new. Aircrafts, especially on aircraft carriers use a device that shows different light patterns based on the angle of approach http://en.wikipedia.org/wiki/Optical_landing_system
I would like to try and do this using directional ultrasound transducers, such that each one will have different modulation, and the drone will determine its angle based on those.
Do you think that such system would be possible to do and could guide the drone to land on say 2x2m landing pad with 0.5m span quadcopter? The idea is that gps will guide it to the approximate location, and then the landing system will guide it the precise landing spot.
Please tell me what you think about this, or if you have some other idea that would be not too hard to implemetnt and would work in bad weather - imagine rain, fog and wind, so no optical quidance and problems with ultrasonic TOF measurements. Actually I am no too sure this would be a better solution than TOF beacons..
