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.

How does the intended client receive the data?
ie, if there's a tower in E Bumphuk Bay and my
dock/warehouse is up in N Fugawee, how does
that ship position data make it's way to me?
