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
  • No problems on GPS reception/accuracry what so ever.

    If you not happy with the device, bring it back for a refund or sell it.


    Now that is a disappointing comment from a Moderator. The aim of forums is for discussion and improvement for the benefit of the community of users. We would hope that Garmin would read these issues and fix the problem. It is a real problem affecting all users of this device, whether they recognise it or admit it. Garmin would be able to easily fix this by software changes, yet they are not doing so.
  • There is definitely a problem with the gps issue, when I first got the watch all was good in regards to gps, now it's got very average to poor, without sharing my tracks with you all, you can be sure I have better things to do with my time than to make stuff up, I have ridden the same rides 100s of times and the latest tracks since latest update shows gps getting worse, it's a real shame, enough for me to consider ditching the 5x pus and going for an edge unit or wahoo bolt, I always use a bike mount just going to re set the watch now and go for another test ride to see if it's any better, again a real shame for such an expensive watch. for anybody using the watch on their wrist I think you are going to have even bigger problems, I don't believe it to be a hardware problem as it was once good, not any more.


    Can you describe the conditions you ride in? Open road biking or MTB trails? How is you're distance accuracy?

    I cycle a mixture road, gravel, mtb, but nothing that should be a problem for gps, pretty open, some woods and forests, but they are not to bad, not much switch backs that kind of stuff, cross country on a mtb, distance wise my tracks have been getting longer, reset watch yesterday, it really is a pain, 1st ride track seems better if someone can tell me how to put up my tacks here I will put up a before and after and one or two with my previous 935 and current 910.............
  • Went for a morning ride today in Hua Hin Thailand, F5X+ shows 48.71km, Polar flow With iphone 6 shows 48.71km... Not able to upload Pictures, (get errormessage every time) but same result or even better that my old F5. GPS is very good on my watch.
    Edit: Uploaded Pictures from almost similar rides With old F5 and New F5X+. GPS is very good on both...48,71/48,71 on F5X+ and 49,46/49,51 on old F5.

    Yes Good idea, I will email to Cliff Pemble and Mike to tell them what moderator of their website are advising their customers (debugging their product), even if your anot from Garmin.

    This is very zoomed out....do you have the link to the Connect activity so track can be examined more closely?

    Edit: please provide GPS FW version
  • I respect that others may have a different needs, goals and purpose for their watch but for me the Fenix plus line is an outdoors watch with navigation as its distinguishing feature. I think the combination of maps and the follow course or routing options are what make this watch (at this time) beat the competition.
    I only view the recorded tracks to see where I was within a 25-50m radius and what trails I used. On occasion I may follow a previously recorded track. But in the field, the watch GPS accuracy is at the accuracy level needed to navigate the surroundings. (I usually zoom map in to around 80-120m for the details and overview I need and under these viewing setting the position lock is always spot on.)

    In this tread there are a lot of complaints, so I thought I might share a success story. Yesterday I was trail running in the woods along a single track course. It was pitch black and (with headlights) I could see around 5-10 meters ahead. A maze of single tracks making it under these conditions a place easy to get lost. I had to cut the run short and instead of continuing the course or back-track which I knew was not the fastest options, I used navigate to start. Voila. The watch calculated a new course which I could follow and I made it back without any detours or wrong turns. I have never gotten lost or made a wrong turn with this watch. This is what I paid for. If I didn’t need/want this, there are many other cheaper options from Garmin and competitors.
    From this perspective I struggle to agree with the conclusion that GPS accuracy is horrible just because the track recording doesn’t show track on the correct side of the road/street or when in challenging environments (tall reflective buildings, thick forests, etc.) show tack in parallel to the path taken.

    What do you use the track recordings for since it has to be so accurate? Or is it just the steep price that makes you have these expectations?

    (GPS accuracy is also better than what I experienced on the Edge 705 and 1000, and F5X.)

    Will try to post links or new images. But anyway, distance is spot on and no drunk man syndrome here. GPS FW 2.30 on the two images from F5X+.
  • Jimoestman, I am very much in line with you, with one exception:
    I consider the watch GPS unusable for pacing during a run. And that is a fair expectation for a sports watch. If they had the running pace right, I would be happy.

    Anyway, I am happy. I bought a Stryd which give me more reliable pacing than any GPS watch probably could. And compared to my F3, the F5X+ has a rock solid connection to the Stryd so it doesn't ever silently fallback to GPS.
  • @ Jim: excellent post. I completely agree.

    DC Rainmaker's opinion regarding the never ending accuracy discussions:
    "There’s likely no topic that stirs as much discussion and passion as GPS accuracy.
    A watch could fall apart and give you dire electrical shocks while doing so, but if it shows you on the wrong side of the road?
    Oh hell no, bring on the fury of the internet!"
