Simrad tp32

I am thinking of purchasing a Simrad TP32 tiller pilot. Is there any problems with this unit interfacing with OpenCPN?

Thanks for any help.

Re: Simrad tp32

these were designed more than 20 years ago. Because of poor sensors, they work hard and wear out and consume more power. They don't work in many sea states because of physical swinging compass. The simrad tiller pilot have several design flaws as well. They cost a lot and aren't very good.

Better to get an autopilot with gyros. gyros and other sensors are cheap. You can get better performance reliability and integration with opencpn for a fraction of the cost.

Thank you very much! Any suggestions for a replacement gyro unit? A cruising boatie swears by Simrad. My OLD autohelm is a Coursemaster that would have to be 30 years old and is still sort of working. Time for a replacement.

Ray..
The manual for TP32 say's it can receive NMEA0183 and thus it will be fine to connect it to OCPN for NAV-mode and wind data if you should have that in to OCPN.

olaf..
Seems extremely robust but what I can find out it's not adapted to receive Nav-data, from e.g. OCPN, to steer to a WP. NAV-mode.

I think you will find it does, email him, he is very approachable.

I have had six raymarines and two simrads, wouldn’t go near either ever again.

A friend has a Pelagic on his 60’ tiller boat, loves it.

They are the preferred tillerpilot for US based single handed ocean racers.

That stuff looks pretty nice. To bad they don't make any below deck stuff.

Re: Simrad tp32

I was wondering about that too, they just seem to use a linear actuator, just like a Raymarine type 1 .....

Only thing missing is a clutch.

Re: Simrad tp32

I emailed the pelagic autopilot and he refuses to release his source code. This is not good for sailors.

This makes pelagic comparable to a closed plotter like navionics. I remember reading on the blog that the pelagic autopilot never sorted out compass calibration while heeling... Basically, he has inferior algorithms like navionics which uses more cpu and battery power on android compared to opencpn.

So yes, it has rate gyros, he doesn't really use them very well, and the cost for this stuff is tiny compared to what he charges. The linear actuator might be a consideration though.

pypilot is free software like opencpn. It is fully supported by opencpn, and is better supported than any autopilot. It has 2 specialized opencpn plugins designed for it.

You don't need to take my word for it.. For the cost of a raspberry pi, some $4 sensors, and a motor controller you can build, or buy for $75, you could compare the performance driving your pelagic autopilot drive unit. Or just use a windshield wiper motor and a belt to the wheel, or if you have a tiller:

Re: Simrad tp32

I have a WP32 and it supports Simnet which is compatible with nmea2000 and will accept wind from the nmea2000 or heading from my Zeus2. It also will read heading externally from my RC42 nmea2000 rate compass. Pretty sure the TP32 supports the same things.

Simrad also has a software update available for download for the TP32.

Here is some more info I just found:
