Re: Time for a New Heading Sensor . . . KVH or Airmar or (Original) Autohelm / Raymar

Yes, compared to ANY fluxgate a gyro stabilized compass is going to be in a different zip code from a performance standpoint. It's a great feeling the first time you get the boat flying off the wind on the pilot with a well calibrated system that can keep up with the inputs.

Confidence inspiring to be sure.

I am curious to the other compass in the Airmar Youtube test?

I dont think theres hardly any fluxgate heading sensors that arnt gyro/accelerometers stabilised anymore.

You should see how things work when you hook up a proper satellite compass.!!

This video directly correlates to my experience.

I've navigated on sleds that have them. It's pretty amazing when you're making 17-18 knots and then surf off the face of a big roller and overrun the wind and the TW solution stays so accurate and the boat just surfs down the face like it's on rails with the pilot. Helps to have great polars.

I've been on boats where that is an instant broach in half the conditions when using the AP.

What is a TE? I think I would do my calibration and configuration on a calm day - most installation manuals start on the other end of "to finish installation and seatrials, take the boat out in a full gale... ). I don't think any of the 3 different manufacturer's MFD's we have on board can calibrate and configure the Maretron SSC200. I would have to use the PC and the Maretron software to do that. Maybe I didn't understand your post correctly.

Re: Time for a New Heading Sensor . . . KVH or Airmar or (Original) Autohelm / Raymar

its was a huge gap in the quite frankly pathetic effort NMEA did with 2K, leaving out how to configure subsystems was a major oversight ( or I suspect they just kicked it to touch)

What is "it" - TE? Still doesn't tell me what it is. What does "kicked it to touch" mean?

Have we caught you at G&T time? (that's what time it is here now, so maybe it's me)?

Re: Time for a New Heading Sensor . . . KVH or Airmar or (Original) Autohelm / Raymar

My compass & GPS are N2k, the rest is nexus 0183. TE = terminal emulator
(Hyperterminal or other)
I wasn't referring to deviation, although I have heard of rate compasses having to be
occasionally recalibrated for dev. after power down;rather the commands for
HDM instead of universal HDG accept by most current devices.
Nexus needs HDM & HDG doesn't show up.

It was tedious in my office, let alone at sea. (In a blow.)
I figure that anything that needs to be configured to begin with, will someday need to be reconfigured at an inopportune time.

Re: Time for a New Heading Sensor . . . KVH or Airmar or (Original) Autohelm / Raymar

Fundamentally NEMA overlooked or ignored the issue of a standardised way to configure devices, One could be cynical and say that, since the major players had so much input into making N2K semi-closed that they manipulated NMEA to avoid spec-ing that area.

Had NMEA for example forced teh requirement that as part of certification that all PGNS had to de documented , this might have solved part of the problem, but then that would open up the network, so that there would be true interoperability ( like maybe interoperability between say one autopilot control head and a different manufacturers autopilot computer, but we couldnt have that now could we NMEA !!!

Mostly a hockey guy myself and since it is cup time, I don't recognize any other sport for the next couple of weeks.
