+--- Thread: MacENC - GPS position problems (/thread-2519.html)
- vov - January 24, 2014
Hi!
we are sail with MacENC and iNavx more than 10000 miles, and generally very happy :-)
But, one small problem could be some time BIG :-)
I saw this problem only when MacENC managed GPS position, but with 3 different Mac and 4 different GPS (including Garmin) connected over USB, NMEA or Bluetooth ...
what's happens - some time (look at the first picture) - position for 1-2 seconds move in any direction, it could be from 10 to 500 miles.

minor problem - your tracking data about distance, speed and etc wrong.
but!!! last trip - we found force 9 storm with gusts more than 50knt, with 2 different, in-depended forecast 20-25knt!!! :-)

We found it on big sail, and can't furl it back! we have just one choice - turn downwind and pray :-) 9 hours until wind slow down and change direction.
unfortunately on the our way - traffic separation scheme with lot of ships. at this moment understanding information from AIS - VERY important ... but if exactly at this moment You position moved to centre of Sakhara ... You are in big trouble :-)
May be somebody saw similar problem?

Since the screen shots are of iNavX and not MacENC, I have moved this thread to iNavX.

may be You are right, but - this problem I personally see just when GPS position send from MacENC to iNavx, and the same moving present on MacENC screen.
I never saw this when iNavx use internal GPS, but I don't have big experience, usually I use MacENC as main, central module of my boat network
I make iNavx screenshot, just because it was closest device from me at this moment

I resolve where the problem :-)
always when error present - engine work for charge electricity
it's strange, it not affect for MacENC, but error present in all connected program such as OpenCPN, iNavx and etc, witch receive NMEA data from MacENC. Even on the same computer, not only over WiFi.
