GPS accuracy very bad !!

Hi,

Tried yesterday the GPS for the first time (GPS + Galileo) and I was very disappointed but the quality of the trace. I am in Paris so in city but I ve never a so bad GPS. In the same area, my Ambit 2 is perfect and following my route but with the Fenix 5X plus, I have more than 40 meters error sometimes !!

I can't understand how a watch costing 4 times a GPS watch can be so bad !! Is there something to do ? I sync it with Garmin connect mobile to have last sat data.

May be it can be a technical problem with the watch... Is there a widget to check GPS accuracy ?

Thanks
  • Do you think better using only Gps without glonass or gallieo?
  • I've typically used Galileo since day #1 on this watch.
  • Jan502 you have to do nothing;), just train:p.
  • Nothing has changed with version 6.0, still this rubbish GPS firmware 2.30...
  • Hi people !

    I don't think I saw that here, did anybody of you tried to export a run in GPX format, then import it as a course and see the distance ? My 5X is doing a good job with the GPS, it's not perfect but quite on par with my Ambit. What was surprising was that it was sometimes shorter on distance, when the GPX traces were looking quite similar. So I exported a few GPX, sent them left and right in various calculator, and all of those are giving a longer distance. Garmin own course tool is giving a longer distance ! So the distance calculation in the watch seems to be not too reliable. At least, it gives less, it's much better during a race ;-)
  • Hi RISBAC, I am interested in your results. There is a few threads about the distance accuracy problem with the 5x plus and the 5/5s plus models. There are other threads about distance accuracy issues across most the Fenix series watches.

    If you don't mind, to where are you uploading your tracks to? Can you please post your results to one of the Distance accuracy threads?

    Just tried this by uploading the exported GPX files in Strava, and seeing the same issue. The exported GPX files show longer distances (although still short, but little closer to accurate) than what's displayed in my watch (Garmin Fenix 5 plus). Thanks for the post RISBAC.

    (updated on 12/9/2018) - I reached out to Garmin Support with the above issue and sent them a sample GPX file from one of my runs. I received the following response -

    So, I was looking at your data. I noticed that there were gaps in between your runs. So, here is an article that will help you with recording time. If you want to extend the battery life then continue as normal with your settings. However, if you want a more accurate reading of your runs I suggest that you look at this article to help improve accuracy.

    I changed my setting to enable every second recording, and it is working much better for me now. [Regarding the concern about battery life, after ~one hour thirty minutes long run, battery life went from 98% to 86%, which I think is still really good.]

    The GPS issues for the Fenix 5x Plus are well documented here. I upgraded from the 3 to the 5 thinking the GPS accuracy would be improved, and unfortunately, I have experienced the same issues. Any suggestions for the most accurate Garmin device for running?
