With the transducer modems, correct. With fiber... its extremely doable. It also hinges on the Iridium network. Currently it's extremely slow. 128 kbps connection rate to be exact. Not much faster than dial up modem @ 56k but a hell of a lot faster than 480bps. They have a new network launch...

-GregLocock Thanks for the reply! That's awesome information i'm going to contact them right away on a custom solution. Thanks again. Also wanted to add Aquacomm got back to me today with a response on my inquiry of the depth and distance issues. Here is the response: "Anthony: Thank...

The weight on the fiber cable I've looked at @ 12,500 ft length, would be roughly 358lbs. The cost is also roughly $4,700. None of that is out of the question when it could allow complete remote control with potentially full video.

Also i think i'm going to adapt the concept of our older Trieste sub-marines for buoyancy. It makes too much sense. Have one large buoyancy tank filled with oil or gasoline. It gives the craft buoyancy and since the gas inside the tank is non-compressible, there are no forces to fight, and wall...

Oh? Did you find some more information elsewhere? All i read is they have two models one at 100bps and a 480bps. They both hinted at the same range more or less. "AquaComm is available in 100 bit/sec and 480 bit/sec versions and in two forms" What did you think of the fiber optic cable...

IRstuff- Thanks for the reply! I had completely underestimated the conductivity of seawater. It is very conductive. It seems controlled impedance is really the only way to go on that front, which more or less eliminates sheathed wire? I would need a mighty thick wire to eliminate loss...

-berkshire I have been looking into wax for ballast and its a pretty cool concept. Just not sure if i understand it correctly. From what i'm reading its stated that in liquid state it loses density. I'm having a really hard time finding data, but i did find a tiny bit. It was a spectrum from...

IRstuff, zeusfaber, berkshire Thank you for your replies! Sorry had a long weekend and was just able to sit down and catch up! You have all certainly highlighted a big issue. First and foremost i do not want to cause any issues with MARPOL whatsoever. So hard ballast would be out of the...

Sorry i meant to make it more clear. This would, in essence, be a traditional sub. It would have a standard ballast hull (outer hull) and have a inner hull that would make up the ballast cavity. Definitely not attempting to use the entire hull for ballast. It must be a sealed compartment unless...

Hello IRstuff, and thank you for the response! It certainly was my plan. The controlling devices were going to be a set of arduino's. One self sufficient system for automatic control, and another device in place for somewhat of an emergency mode or failure mode should it occur (it will)...

I checked it out! It looks absolutely amazing! Unfortunately I don't think wife is too keen to leaving Wisconsin :( I have friends who live in Sacramento though so i'm really trying to make it out there soon!

I'm assuming you are referring to cellular. I wouldn't use cellular unless i was close to shore-line and able to grab signal. But even then, water is far too dense to transmit RF. My theory was to have a deployable antenna. A bouyant platform more or less than can detach from the sub, float to...

ps: with the new waterproof cells, are they as common below as above? (I don't dive anymore) I can't wait to take a diving course. Hopefully this year ill get down to florida and actually make it happen! Though i could probably still take a course here! As to your PS. "New waterproof cells"...

Hello Gents. First off i'm new to the forums! Glad to be here, some reading through existing content tells me i'm in the right place. Next a bit about myself. I'm extremely ambitious! I live in Wisconsin. I love the outdoors i'm just afraid life doesn't allow me to experience it all that often...
