I am want to develop a network of AIS receivers with coverage of the
US inland waterways(miss, Ohio, Illinois rivers and the gulf).
Searching the web mostly results in sites targeted for cell phone
carriers. Does anyone know of any sites that would be more appropriate
for this type of need? How do locate sites/towers to be used for
repeaters for example?

Ideally well located amateur towers would probably be best.

Thanks in Advance.

isn't the coast guard already doing this? why would an individual want
something like this????

The short answer is no. There currently is no river system wide
network of receivers managed by any company or agency.

We currently have coverage in three areas, but in order to provide a
useful service for safety, monitoring and performance management, more
coverage will be needed. This could either be under the umbrella of
either a non-profit organization or as a standard business.

Now that we've covered the premise of the question.... any help?

the longer answer, found in a few short searches is, that its coming... see
the presentation at http://www.gicaonline.com/media/tools/070827_cris.ppt#1

You state that this could be a 'non profit' or 'standard' business... and
that it could be for safety purposes... in which cases i agree with others
that have stated that there is a possible liability issue, whether you see
it or not. once something like this is advertised as a method to improve
safety there is a penalty to pay if it becomes unavailable. Also, renting
space on a tower to a commercial operation can expose hams to loss of
protection of their towers as amateur in some areas... in some places it is
considered the same as changing the purpose of a building from residential
to commercial/industrial which could endager protection under prb-1, or at
least cause headaches for an unsuspecting amateur.

You also now state 'we have coverage'... is that you personally, or you as
this hypothetical 'non profit' or 'standard' business?? if so, please state
your entity rather than hiding behind a gmail account. and let us see what
type of product you have produced in these 3 areas.

Thank you for seeing it. Imagine some kind of incident
occurrs where this system failed. They examine all
the equipment on the ship, on land, wherever.
They find that the tower was used, 50 years old, purchased
from an SK ham estate sale, installed by some local
amateurs over Labor Day weekend, using the original
guy lines and hardware that were on the tower in
it's previous install, and in violation of someone's
CCR's because it now holds some kind of commercial
aid to navigation and the tower owner was away for
the weekend visiting the Hamfest in Dayton.

Even if nothing goes wrong, there's something very
wrong with that picture.

Not to mention, I still don't understand what all
these ground based RECEIVERS are supposed to do.
How does a receiver on shore assist navigation
for a vessel in the water?

AIS is not only an aid to navigation, it's just like APRS for ships, it
allows those ashore at remote locations to monitor the position of vessels.
On a river system I guess it could be used to monitor traffic flow, optimise
lock usage, find out when your vessel is likely to arrive for unloading etc.

The information trasmitted by the ships gives heading, speed, callsign and
other data such as length, beam and draught.
