I'm looking at starting the project by writing a unified driver for NMEA 2000 and NMEA 0183 that extends the Linux /proc pseudo file system. NEMA talker only works with NEMA 0183. Most autopilots only understand NMEA 0183, however NMEA 2000 is a more modern h/w and s/w protocol. Gotta support both these days. I'm committed to Linux, and am considering the Moblin distribution. You mentioned 'TSR', which makes me think of DOS. I shudder at the thought that a mission-critical system runs on a Microsoft O/S. Sounds like your concept is simple and direct. It should work well. I am considering a more comprehensive system, and it is likely to take a lot longer to put together than what you discuss. Mike Peter,

Thank you. My wife and I are researching instruments for our sailboat. We have already decided that NMEA 2000 is the way to go. I was quite excited about the Maretron WSO1000, but its fragility is now a concern. Do you have any further information on this? Michael Interesting article… Thank you.

me again, peter voussem.
in the meantime a colleauge and i have found some other projects that concern themselves with auto pilots (a.p.)
so i would reconsider my opinion about paparatzi. perhaps it would be a good idea to implement the a.p. as a virtual device that resides as a tsr application in the computer. i had some thoughts regarding some principles of the design:

2 modes:
1.stand alone- with i/p from gps reciever and a course selection.
a feedback from rudder(pot)or steeringwheel (pulses). an output to a drive with directional info. the unit should recieve gps sentences, containing course + speed. validate the gps senstence, calc if on or off course, and take appropriate action: left or right rudder. the reaction should be proportional to the deviation .

2. slave-
autopilot with chartplotter eg cmap.
this device will recieve data from chartplotter in the form of autopilot nema senctences. recieve nema sentence, validate, determine error, output action through printerport or other.
have feedback from rudder(pot) or pulses from steeringwheel.
o/p to motor with indication of direction (left or right rudder)
in the back ground menue there should be a strenghth adjustment for rudderaction and feedback and a cal function for rudderresponse.
both a.p.’s must display “ok” (status)function, maybe time and position independently of map plotter application( somewhere in the corner or so)

mike,

MY NAME IS PETER VOUSSEM. I LIVE IN AUSTRALIA AND I WAS VERY INTERESTED TO READ YOUR ARTICLE RE MOD OF PAPARAZZI AUTO PILOT TO A MARINE ENVIROMENT. MY PROFESION IS ELECTRONIC TECH WITH A SMALL MAUNFACTURER HER IS AUSTRALIA. DONT KNOW WHAT CONTRIBUTION I CAN MAKE, BUT PLS LET ME KNOW IF THS PROJECT HAS LIFTED OFF AT ALL AND AT WHAT STAGE IT IS. THE REASON FOR MY INTEREST IS THAT I AM BUILDING A MOTOR SAILOR. RECENTLY I BOUGHT A CMAP CARTPLOTTER /MAPS FOR TO USE ON A LAPTOP/PC. BY STRINGING A NEMA TALKER AND LOGGER TO THIS PROGRAMM I COULD ESTABLISH THAT IT ACTUALY OUTPUTS VALID NEMA SENTENCES FOR AUTOPILOTS. SO WAHAT I LOOK FOR IS SOFTWARE THAT DECODES NEMA, STRIPS THE "OFF COURSE" DATA OUT OF IT AND SENDS OUT CONTROL SIGNALS TO A DRIVEMOTOR AND RECOGNISES FEEDBACK FROM RUDDER. THE PAPARAZZI BOARD TWOGV1 SEEM TO BE A VERY SUITABLE BASE FOR THIS PROJECT THOUGH I DONT KNOW WHERE TO BUY IT AND HOW MUCH IT IS. LOOKING FORWARD TO YOUR REPLY WITH KIND REGARDS PETER VOUSSEM HI MIKE.

So you think all of the products you mention are inferior to NavPak? Jenia, sounds like you are either an alias for the NavPak author, or a relative or close friend. If not, you are entitled to your opinion. I very much doubt that most sailors would agree with you, however. My computers are fine, thank you very much. They run lots of software all day long, every day. I'm a software developer with 32 years of experience. NavPak died, and there is no-one to blame except that the software isn't up to snuff. No point beating a dead horse. We don't agree, and this blog is not intended to be a venue for argument. 'Nuff said. Too funny.

Maybe you should check your computer. My criteria is stability, display speed, versatility of chart formats, and connecting instruments from various sources. I tried demos for Seaclear, Fagawi, Nobeltech, raytech, Tiki navigator, Oziexplorer, Coastal explorer, Tsunami, and the Maptech program. All of them fell short on my criteria except NavPak.

My own experience was that I found NavPak to be quirky and it crashed a few times. I did not review RayTech RNS. Practical Sailor had another person write that review. The test protocol for my reviews are fully described in the articles. Out of curiosity, what other navigation programs did you try, and what were your criteria?
