Any hope for improving GPS track?

@annnnna5 could you share a link to the activity in question?
My S7 has been pretty solid, and usually comes within about 0.5 - 1% of my wife’s Fenix 5 when we go out together. Only really had an issue once when the track took a surprise detour, but my Garmin would do that as well every now and then.
-
@annnnna5 20% difference is not just some wobbling around, it’s most probably a major GPS error, so should be very visible if you compare the track of your S7 with the track on the phone. Can you show us pictures, or the activity itself?

@isazi this is what I was thinking. An erroneous GPS fix throwing the track off and back can happen. My Garmin once teleported 800 m into the forrest and back.

@aleksander-h my Fenix 2 once teleported me 26 km away

@isazi You must have got an impressive half-marathon time that day

@isazi My S9baro transported me from Colorado, USA to Spain once:)

@brad_olwin I seem to recall that you are in Colorado, so I would think that your experience would be similar to mine. I posted these images in another thread but it didn’t get the traction that this one has, so I’ll repost them here. The blue track is from a Garmin and the purple one is the Suunto 7. Based on these, it’s pretty obvious why the distance traveled according to the S7 is always high. Are GPS tracks like those in the image the norm?
-
@randy-penn I don’t see this, I have many, many activities wearing the S7 and S9baro. If you are not wearing both devices at the same time and on the same arm you cannot compare them. The first below is a hike, both watches on Best GPS, they are identical, S7 is red. The second is SkiMo S7 is on FusedTack and S9 on Best GPS. Here you can clearly see S7 misses some turns. That is expected as GPS fix is at 10s intervals. S7 is red.
Are you sure you are on Best GPS fix?
-
@brad_olwin Yup, that’s best GPS. Your RMNP tracks are pretty rough, but the Dakota Ridge ones look acceptable. I don’t know why my S7 tracks in wide open, treeless spaces are so poor.
-
@randy-penn The RMNP tracks are rough because I used 10s fix and FusedTrack doesn’t work with skiing, not a good combo. I can show you many trail runs where S9 and S7 are indistinguishable.

@brad_olwin How about some hikes? I don’t do too much on foot where I’m moving faster than about 3-3.3 mph

@brad_olwin
Hi, i Have a question about Fusedtrack…
On hiking,then low speed,with GPS at 10 sec. Does It work? And how…well?
Thanks! -

Very few, about everything I can show you has great tracks, sorry. I do very little hiking or walking.
-
@brad_olwin I’m coming to the conclusion that low speed is the issue with this watch and poor GPS tracks. Should be fixable, as virtually all other watches with the same chipset provide good tracks. I’ll keep my fingers crossed that it gets fixed somewhere along the way. Thanks for the info!

@Randy-Penn
Here is an example of S7 and S9 onFusedTrack. The 7 is better, I think in red. We were moving slowly here.

@randy-penn my walk 2 days ago had no issue despite me walking slow

Agree.
Most of mine are walking or paddling, so nothing major speed wise - usually under 6km/hr.
And yes occasionally you hit the odd bump/hiccup, but generally find the track is easily within the river/canal while paddling, and while the walking track my wander slightly from side to side on the road, it virtually always gets it right. I occasionally get the odd bump /hiccup - maybe one in 5/6 tracked activities.Don’t foget that GPS fixes are normally only accurate to around 5m - so even with great fix to numerous satellites, still not going to be perfect.
