No GPS data

OCPN was working great at 4800 baud on com 1. I have just installed an AIS transponder so the serial data has changed speed. I changed the port to shared AIS at 38000 baud on the GPS tab and selected COM 1 under the AIS tab. Now everything works except GPS data. There is other nmea data that shows up but no GPS data.
Seaclear works just fine if I close OCPN down and open seaclear... for some reason OCPN cannot see the GPS data.

Re: No GPS data

I used windows terminal to capture the data...do you need it specifically from the OCPN data stream window?

Re: No GPS data

GWB....

I see AIVDO data in the stream. This should be your ownship position.

What version of OpenCPN are you running, please?

Dave

Re: No GPS data

I do see my boat in the AIS target list. There are no others because my boat is in the middle of nowhere!
This is an AIS500 transponder made by Raymarine.

There is no GPS data here.

The AIS500 manual indicates you have to enable GPS output via configuration.

from page 44 of the manual:
Quote:
NMEA sentences !AIVDO, !AIVDM, !AIALR, and !AITXT

With NMEA GPS output ON
$GPGLL, $GPGGA, $GPVTG, $GPGSV, $GPGSA, $GPZDA, $GPRMC, and $GPGBS

I don't know, but surmise:

It could be backing into the location via the VDO sentence.
or
It remembers where you were the last time it actually had GPS data.

You titled the thread "No GPS data". I'm simply telling you there is no GPS data in the logs you captured and included in the above messages. According to the AIS500 manual, you can enable it to produce GPS data via configuration. As it states in your manual, a GPS will produce any/all of the following sentences: $GPGLL, $GPGGA, $GPVTG, $GPGSV, $GPGSA, $GPZDA, $GPRMC, and $GPGBS (the preceding "GP" could be different).

Re: No GPS data

GWB....

The AIVDO sentences in the log contain your location. Unfortunately, OpenCPN currently ignores AIVDO messages with message ID=18. This will be corrected for Version 3.0.2.

Sorry you are temporarily lost
Stay tuned

Dave

Re: No GPS data

Thanks for that. I'll try to figure out how to turn NMEA sentances on from AIS 500. Strange because all other NMEA data is there...
