Electronics

This winter I am revamping the whole instrumentation on board. I have drawn up a diagram of the entire navigation and communication system. This will include the onboard pc.

Information comes from the sensors Windspeed and angle, Depth, Log (speed), GPS, AIS, SeaTemp and feeds via SeaTalk Network and NMEA into a multiplexer. This feeds in to the DSC VHF, into the AutoPilot and Plotter and also into the PC. On the PC at the nav station I will be running various software tools like a simple chartplotter program, instrument repeaters, a tactic tool for speed optimization, weater routing software (GRIB files), internet, this BLOG and more. Also I will be logging my performance data for later analyses to see what works and what doesn't.

It's just for fun because the serious navigation will be done from the Raymarine C70 plotter which has all the information already but this will be a nice and fun addition. Currenly most of the installation has been done. It's now up to testing and refining the various software components. A report will follow!

Cheers
Nick
