B&G H2000 NMEA FFD -> OpenCPN

[ghotihook]

Hi,

I have a Furuno GP-31 providing GPS data to a H2000 Hydra B&G Network. An NMEA Out from the NMEA-FFD into a wifi bridge works well and I can access NMEA data via OpenCPN, IOS apps etc.

The problem I have is the GPS signal being transmitted appears to be an old format (NMEA 1.5??)

$IIGLL,3350.583,S,15112.013,E,,*6E

It matches the B&G FFD manual so I know that the B&G is outputting the right sentence but it seems to be missing both the time and status fields. I am guessing OpenCPN is unhappy with the 'invalid' GPS fix and discards.

Does anyone have any ideas on a fix for this? have I missed a trick or am I stuck due to old hardware.

Thanks,
Alex

Has anyone got a similar setup working?

Alex..
The sentence "$IIGLL,3350.583,S,15112.013,E,,*6E" is OK and O can decode also NMEA0183 version before 2.3 where it was changed. No problem.
But since your sentence misses data for "IsDataValid" pos(6) OCPN will not use that position.

Thanks I feared that. I’m surprised that the fairly standard hardware outputs bad data. Does anyone have the same hardware working? Furuno/B&G hydra?

You could probably work around this with the NMEAConverter plugin.

Warren, thankyou!

NMEA converter did the trick, would not necessary recommend for use in anger but for my purposes which is analysis, its perfect. Instructions can be found in below link
