Hi all,
Sailing season has ended for me, next week my boat is on land and I'll
prepare it for winter.
So, now begins the "silly sailing season" when I get to prepare for next
years sailing.
This year we had some semi long trips with legs of up to 80-100 nm and a
few weeks at sea. While sailing I have my plotter right at the wheel and at
the moment I lack AIS information there. We did cross the bigger shipping
lanes and of course had to keep a sharp lookout, as always.
I will connect an AIS receiver to be able to see the other ships
earlier/better. The bigger ferries do 30 knots so in a few narrow passages
I would have liked to see where they were going earlier. But, I would also
like to see other boats that use aprs on my plotter and of course I would
like to have pskmail integrated too. So, I built an aprs to ais gateway.
That way I can have both AIS, APRS and PSKmail tracks on my plotter. It
converts APRS pos messages into NMEA AIVDM with AIS Payload containing AIS
message type 1 (Position report class A) which any AIS capable plotter must
handle. I intend to add type 5 also to get some more data across. I have it
on a PC now but that won't do on the boat, I'm thinking arduino to save
power and size.
So, I just wonder if that kind of thing could be interesting for others
with boats? A small box that lets you connect AIS and APRS sources to a
dedicated plotter or software (OpenCPN for PC or android works fine btw).
