So, just getting AIS into a PC display system reliably while trying to do
other things is a big task. Introducing ARPA is something the customer wants
to do mainly to highlight vessels that have ARPA returns but no AIS, as these
are the more worrying targets. I'm skeptical as to whether it will work on a
PC system in the real world though. If I can find some simulator or even
sample ARPA data I'd trying pushing it in & see what sort of throughput we
get before everything falls over.

==============================================

I have a Furuno Navnet RADAR with the optional ARPA board. I believe
there is an option to transmit the ARPA sentences over the Navnet
interface to a secondary display. I'm pretty sure the ARPA sentences
are documented in either the user manual or installation manual, and
either should be online in PDF format on the Furuno web site.
