GPS accuracy - track and field
-
@thomas-ma We need to know how the watch was set and whether or not the AGPS was updated or not.
-
@brad_olwin Hi, where can I check the setting?
-
@thomas-ma Nice artwork!
If you have a Suunto 9 you can find the information @Brad_Olwin asked for under settings->general->aboutMy own Suunto 9 was also struggling with GPS yesterday so it’s maybe just a bad day.
-
Did you stop your move during your run?
-
@surfboomerang Hell yeah, I experienced some bouncing in GPS signal yesterday, however there was never problem like this before.
Interesting

@thomas-ma
It doesn’t really look like non accuracy, as it is really “geometrical”
Have you eventually transfered the same workout to another plateform to compare the representation ?
SA activity link or fit file may help to see what is inside (wrong data, wrong representation, raw data behind for suuntoguys). -
Thanks all. So I followed the instruction above and switched to another GPS system to “Galileo.” Attached is the tracking map.
My next question is the accuracy: I ran 12.5 laps, which should end up equal to be 5k. However, the Suunto shows 5.38km. I ran on Lane 4 which is 423m per lap, and it should equal to 5.28m, I know 100m discrepancy is not huge but my friend is using another brand, Coros and his watch’s discrepancy is only 10m. We ran side by side as well.
-
@thomas-ma i think coros has a special feature for lap running where it averages out gps descrepancies so you get nicer track + more reliable distance.
-
@дима-мельниченко Agree. In general I am quite happy with my Suunto 9 tracking.
Does anyone know if there is any different GPS tracking function between “Track and Field” vs “Running” function? If no, should I just use “running” function for running at the sports ground going forward?
-
@thomas-ma I noticed running profile does not record GPS every second, but a random interval between 1-4 seconds. On road races with distance of half a marathon I noticed the watch is always spot on in distance, but on a 400m track I can imagine it cuts the corners less accurate then it should do.
Maybe that explains the difference.

This is from this morning in Amsterdam. Standard running profile, GPS+Beidou.

@isazi I know the place well

@isazi image isn’t from SA, right?
-
@дима-мельниченко Runalyze with ESRI satellites view.
-
@isazi said in GPS accuracy - track and field:
Interesting. Next time I will try the GPBeidou system and see if it reports better result.
And you can tell from the screenshot (from Strava) my GPS is completely off track.

@thomas-ma
Hi, have you tried “Track and Field” Sport mode for running on track? I can remember that I read somewhere that it (should) has some special setting for tracking running on Track. I have never tried it by myself. It just rang the bell for me, when I read your post…
-
@thomas-ma keep in mind that the satelite overlay isnt always 1:1.
-
Thanks. i understand it is not always 1:1.
May be next time I will try the normal “running” mode while running on track and see if there is any difference.
-
So I run another 10k using the regular run function, and here is the map from Strava. 10k should be 25 laps, but I think I ran 24 laps + 250m(?) from the map.
-
my 10k, it’s quite accuracy
