RE: [rcpilot-devs] GPS NMEA support

[Peter W. <pe...@wo...>]

We were going to start by getting his GPS to talk to a Java program.  He's
going to lend it to me for a while to see if we can get that to work and
then we might move on to other instruments.  I haven't sailed much in years,
but I spent a lot of time out on Lake Ontario sailing when I was in school.
My sailing experience is mostly limited to dinghy racing.

We found a FAQ that describes the NMEA protocol and we both have RS232
experience.

Really what are you doing?

Don't know if I ever mentioned it to you but I use to sail quite a bit.
I had a Saga 43' built for me some years back. I just sold it recently.

I kept her on Lake Champlain and took her down along the east coast of the
US a couple of times.

I also got to do some sailing in the Bahamas which was totally amazing.
67mph winds and all.  ;-)

The one thing that bothers me about NMEA is the cost of purchasing the
protocol specs.
I don't remember what it is anymore but I remember sending them an e-mail
about it when I found out.

I have most of the NMEA protocol decoded on the rcpilot site (I found it
somewhere on the net at one point).
I needed it to build the autopilot.

The other protocol I worked with a bit was SeaTalk. All the electronics on
my boat were Raytheon.
Very cool stuff. Radar, Chart plotter, DGPS, Autopilot, environmental
telemtrey, and more.

I had the whole boat running off of my laptop. Or I could use the repeater
up at the helm.
