We are currently working on a system that is taking information from a variety of sensors (uBlox GNSS, Airmar DST800, Atlas-Scientific environmental sensors) and publishing it all to a webserver running off a RPI3 and displayed in real-time through a web interface.
We are doing some tests this afternoon and tomorrow. Our plan is that it could be running off the onboard RPI, but also on a separate RPI if you don't want to use / don't have a BlueROV to run the system off.
I think it would be nice to have the option to show it directly in QGC interface, and I think there are several options on how we could do this with mavlink messages. Maybe @enriquegsancho could help out?
@coastwatchalliance, the Airmar sensors is meant for installing on a vessel hull, so depth rating would be only a few meters. I would be carefull about taking it too deep, even if you have a whole pile of them. One option would be to take the electronics out of the "box" and rebuilding it using a 2" enclosure. The only thing I´m not entirely sure about how to do is the membrane. Do you have any ideas?
