GPS Accuracy

So it begins.

I will have mine Fenix 5 on Saturday and will start doing comparisons to an Ambit 3 Peak. I don't have an F3 to directly compare to as of now.

Anyone have an F3 and F5 to compare?
  • Could anyone post some walking/hiking tracks, please? Because of terrible hiking tracks and even walking in perfect conditions (my Edge 800 and FR 630 did much better), I had to return my F3. My F5 is on it's way and if the history repeats and Garmin didn't improve in this regard, it will be quite "amusing".

    Here's a nice hike with open areas, areas with lots of tree cover, elevation changes. Overall, a good variety in a hike. It's not my GPS proving grounds tough, but should be fairly stressful. I also have tracks of the same day, but with an Oregon 700 that I haven't downloaded yet.

    edit: GPS+GLONASS, 1 second.
  • Probably good the thread wasn't titled "F5 much better than F3HR and you should Upgrade" I guess then :p


    You are not helping.... But if you want to troll me, go ahead, have fun ! :rolleyes:

  • The new 2.90 Software Update just put me on GPS v4.30. (nothing mentioned in the changelogs about it though)
    It's already too late here in Europe so it'll have to wait for tomorrow to be tested.

    WOuld be helpfull to add info on gps vs gps+glonass and 1sec vs smartrec (looks like smart to me?)

    Edited to add the information.

    GPS+GLONASS, 1 second recording.
  • Just to add to the hiking in the woods comparisons http://www.mygpsfiles.com/app/#AgkGMdai out walking my dog with Fenix 5, Fenix 3 and iPhone Strava App
    Fenix 5 and Fenix 3 both on GPS+GLONASS with 1 second recording. I'd also put the iPhone in to flight safe mode to eliminate any interference from LTE/WiFi/BLE and to take away any advantage of augmenting position from phone towers or wifi.

    All the tracks have their moments, good and bad, but when you zoom in the tracks are rarely more than 5 metres apart and are similarly where I know I walked. iPhone is smoother, but there are far fewer recorded points (Strava App equivalent of smart recording). The places where the tracks go off are often where I stopped for the dog to answer the call of nature or wait off-trail for another dog to pass.

    I don't want to add anything, I wanted to clarify some some aspects of his run.

    The question was clear and simple : if the trees in the area (that he ran) had leaves or not.

    If the leaves were on that means that the watch did a fine job with the tracking under the trees, in those small patches of forest because usually the F3HR does not cope well in that scenario.

    With no leaves in the trees could mean that the watch had it easy, so for me that particular track does not tell the whole story of the watch potential so I would ignore it...

    I've seen people countless times running in "GPS friendly" scenarios (meaning lots of open space, no medium or high buildings, very few trees, little or no vegetation) and claiming that the F3/F3HR has the best tracking there is... And to be honest I don't blame them, they were correct but that great tracking was in part due to the environment. Once you put them in the city environment to run they were like "WTF happened to my watch, I think it broke".

    Different people have different needs... I need the F5 to perform good in the city and so far, even if I admit that is a little better then the F3HR I still don't see a big improvement that I would have hoped to see given the F3 GPS performance saga.

    Yes, I know, the F5 is new, the software could improve but to be honest that's exactly what I thought and hoped about the F3, then about the F3HR... and nothing amazing happened... they made small improvements but they never managed to bring it to the level of performance of my old Garmin 910XT that I had 5 years ago and i feed the need to remind everyone that 910XT did not have glonass.
  • Good points, can you share some of your city tracks ?

    I've been following the GPS accuracy threads, and will add my own 935 vs fenix 5 (2.72 beta) comparison, with GLONASS on, and 1 second recording. What I've been seeing is that although they're close, the 935 gives me smoother tracks. The fenix also appears more likely to stray.

    Thanks for sharing, wow the F5 didn't like the Ferry building did it? Complete multipath mitigation failure...And as usual more mileage on the F5.

    @ChevronLugs - nice hike, saving this for this summer as I'm planning to get back out there ;-) Not knowing the area it's hard to tell if it was good or bad ?

    @all - has anyone seen an F5s track being shared ? We've had mostly the F5 tracks by multiple users, F5x tracks shared by
    NYanakiev7 but no F5s ? Since it has a completely different bezel I wonder if it would maybe perform closer to the FR935 ?

    So we have a new SW/GPS version to test, let's see !
  • has anyone seen an F5 track being shared ?


    Just checking what you're after here, as plenty of us have shared F5 tracks (that's F5 and not 5X or 5S). Can I assume you are specifically after a 935 vs F5 comparison in an urban canyon environment (which is what PatrickNSF just provided).
