I am a long time user of OpenCPN
and think that something has gotten changed in the code pertaining to an established GPS
fix/location. I have two sources for GPS
data, one from my AIS
, the other from an older Furuno
GPS. Before I owned the AIS
, the Furuno
was my primary GPS system. The then current
version of OpenCPN
would accept the $GPGLL sentence from the Furuno and give me a location fix on the chart. Green ball in the satellite
icon in the upper right. Since I got the AIS, I haven't used the Furuno at all, and it is turned off, but kept in the system as a "backup".
Now, running OpenCPN v.5, if I turn off the AIS (which sends and RMC sentence) and turn on the Furuno, even though it is sending a $GPGLL message, this no longer seems to be adequate for OpenCPN to establish a position and show a green ball in the satellite
icon. I have tried turning off the require checksum just to see if that was the problem, to no avail.
Anybody else having problems with establishing a fix using just the GLL sentence? Any ideas of how to resolve?
