Much better traces with the last version.

This the main canyon of La Défense. The traces were recorded the 2nd and the 3rd of May.

The zig and zag are my exact changing of direction to avoid people. I'm not running and I'm walking slowly.
Here is one from March 2017 on my 5X from the same place:

Before, as you can notice, the drunk syndrome on that urban canyon was long zig and zags and I was walking straight....

Here is a picture of the place:

There are a lot of discussion about it to dimostrate that it is a algorithm issue and not a GPS track issue.

The better GPS track with 4.31 confirm that a better track is not enough to have the more accurate…

Here is an example yesterday of tracking in urban streets, dense woodland and open fields, comparing 6X Pro Solar (green) to Polar V800 (red) and Galaxy S10+ (blue). You can click and zoom in for better…

So you're familiar with Halifax west yorkshire? Of course you're no so haven't a clue where I walked, other than around 1m or so offset at the bottom the rest is EXCELLENT, the walking through trees…

It's still a significant difference for GPS traces. How do you explain the difference ? The Fenix is cutting a lot of turns ? or is it possibly the S10 waving too much ? The real question is always what is the REAL distance. The S10 is doing a decent job for GPS, but it's far from perfect also.

Yes, the real distance is the question.

As I see it, the S10 is very consistent, and I believe it is the most correct, and it never shows that much too short as the F6Pro.

So I believe the F6Pro has medium reception, or poor application of the GPS-data, and probably cutting turns.

I will try to bring the F305 along the next few days to see how the F305 differes when walking.

Comparing the S10 with the F6 in the woods on a hilly run, they were quite similar. But the Garmin distance was adjusted, and too short. The GPS of the F6 is fine (especially on the inner wrist), it's really the algorithm that is a problem.

For me now gps is much better I’m using 6xpro gps glonass 1 sec and last gos 4.31

0 honza_81 over 5 years ago

For me, not so good :-/. F6Pro, FW 9, GPS 4.31, 1sec, GPS+GLONASS. Cycling is excellent, but running is worse than on VA3.

There is clear view all around, only tribune on the left side, but there the track is good...

Running on 2nd inner lane.

While I'm not posting a specific track, I did receive my Fenix 6 today and went for a walk with my trusty Forerunner 645M on my right wrist and my Fenix 6 Titanium Sapphire on my left wrist (with the 9.00 firmware). Surprised to see the difference in measured distance to be so much. I've not adjusted the GPS settings on the Fenix 6 before this walk, but will try some different settings before I go for a 6km jog tomorrow.

While walking, I'm not that surprised... The distance calculation is not that great for slow speeds. What is the pure GPS distance measured by the F6? Did you check on Strava or with any tool which can calculate it from the GPS points ?

0 RISBAC over 5 years ago in reply to honza_81

The distance must be a bit short, right ? On a track, it's not easy for the Sony chip... Did you try wearing the F6 on the inner wrist? It really gives me good results every time. Not perfect, but quite solid.

0 TheSalamander over 5 years ago in reply to RISBAC

I completed a 6km run this morning. F6 was 6.00km, FR645M was 5.86km. Both were matching each other well up until about 2.5km when there was a 120m deviation which remained.

The only GPS setting change I made was to switch the F6 to be GPS only (i.e. no Galilei/Glosnass). I may end up purchasing a Stryd at some point, or load the data into another tool. I will also look at some of the other suggestions.

0 RISBAC over 5 years ago in reply to TheSalamander

I'm waiting for my Stryd to have a solid reference for the distance. For now, I'm retracing the runs sometimes, and I compare. The F6 using GPS and on my inner wrist is giving very solid results, I would say on par with my old Ambit. BUT, with the lockdown, I ran mostly in the streets near my place. I wait for runs in more various places to confirm.
