Thanks, got it.  And it is only AIS sentences 18 and 27?

18 is decoded here: "drivers/driver_ais.c" line 878 and later.

And turned into JSON here: "gpsd/gpsd_json.c" line 3066 and later.

27 is decoded here: "drivers/driver_ais.c" line 1136 and later.

And turned into JSON here: "gpsd/gpsd_json.c" line 3580 and later.

I don't see an obvious problem there, but I did not look hard.

Lat/Lon is returned in decimal degrees.  Is that what you are expeecting?
