Hey all,
I really want to do an underwater remote vehicle for my final year project at university, the only problem I am facing is the camera data feed for first person view, more specifically the bandwidth.
Due to the attenuation of EM waves through water I want to use an ultrasonic modem to communicate with my ground station, the only problem is that this method has a limited carrier frequency (e.g. 100 kHz) and hence bandwidth would be quite low.
I had the idea to use a towed buoy on the surface that could relay the information but this method seems a little clumsy, basically I want to know what is the lowest bandwidth camera signal available?
I was thinking that there might be a low resolution greyscale data protocol out there but I haven't found anything yet because the RC community is obsessed with high resolution, 2.4 GHz 'FPV'.
Any help with this would be appreciated, thank you.
