Re: [PSUBS-MAILIST] Drop Weights
Jay,
You are on Andros, you cant find an acoustic tracking system there :) ?
The most "inexpensive" acoustic nav system in the world is gonna be the
Desert Star stuff.
The simple pingers/pinger receivers are about $300 USD - $500 USD
The lowest cost full 3-d tracking system would be the short-baseline
system. Those start at around $6K.
Still kinda spendy.
Any other new acoustic nav system from say Linkquest, ORE, Applied
Physics, etc. will be in the $15K to $20K range. That is at the lower
price spectrum. The sky is the limit from there.
Every once in a while some company comes out with an acoustic nav
product for the recreational diver market. The price range there is
usually below $3K or so. But those products generally disappear pretty
quick. It's a very small market where testing R&D is pretty expensive.
One suggestion:
1) Contact lease agencies in some oil patch region like GOM or North
Sea. They may have older used equipment like ORE Trackpoint II's you
could get 'cheaply'. Also some universities probably have stuff sitting
on shelfs.
Building one is a reasonable effort, sometimes Univ. Students build them
for the AUV competitions. You might be able to build a working one for
less than $3K if your time was free and you only had to buy beer for
your test boat crew...cheap beer, like Schlitz or something.
Although if I was getting acoustic gear for a sub, the first thing I
would get would be voice comms. Like an OTS or the newtcomm...

Andy,
That's the ticket! Use to frequent that place years ago when we were
installing moorings on the wrecks up there. Thanks.
Another question: Is there any economical (within the typical PSUB cheap
budget) for a short-leg acoustic pinger navigation system?

Desert star has used there smaller floats instead of syntactic for several
shallow apps. They also used hollow steel spheres that I think we got at
mcmaster. I have no idea what sizes they come in.
