Altimeter recordings while running
-
@Tadas-Linge Try doing an activity with the GPS off so you can get a sense of how things are going with just the barometer, and I suggest you do this when the weather is changing…Then think that there is an algorithm that avoids excessive drifts using GPS data

Buongiorno, mi servirebbe sapere come eliminare da un sunto vertical un itinerario salvato .erroneamente ho cancellato l itinerario dall app del telefono senza accoppiarlo prima all orologio.in tal modo si è cancellato solo da telefono e non da orologio.fatemi sapere come poter fare . Grazie intanto saluti

@Tadas-Linge it may drift but FusedAlti works constantly. However - how it corrects altitude is unknown in details to the public.
Generally - when you’re using GPS with highest quality available for your watch, you don’t need to do any manual calibrations as FusedAlti will take care of it.
Also, keep in mind that this isn’t perfect and there are plenty of variables for each activity. Simply don’t expect you’ll have 1m accuracy each workout.
I usually run on flat ground and have anything between 0 and 6m of elevation gain each workout.
I have the best results when I’m cycling and have my watch mounted on the handle. I usually have under 10m error for 30 - 50 km ride with elevations averaging 250 - 350 m.
But errors when running are more significant - it may be because of wind, hand movement, clothes or temperature.
All Suunto watches from S-series that have barometer have FusedAlti (S9B onwards).

@Łukasz-Szmigiel thank you very much!

@Łukasz-Szmigiel Suunto Vertical.pdf
i have made some comparison. I took different points from my yesterday run with measured altitude on the left side and on the right side what Suunto app says as altitude in the same point. as you can see run starts with no deviation and then steadily deviation increases. I have finished run with -40m measured by watch compared to Suunto app. i have synced watch before run with app and manually added altitude of start point, also was using dual GPS.
my only one concern now if it is acceptable by Suunto tolerances or this watch should be checked by warranty… -
@Tadas-Linge while OSM may not be perfect in terms of accuracy, 40 m seems like much. Especially in places when the watch reports -9 meters.
How do you wear your watch while running? Was it windy or raining during the run? Can you test it on a different run while wearing the watch on top of your clothes or on a second wrist?
Edit: if you’ve finished with a large, negative number, it seems as if something pushed on the baro sensor. Maybe some dirt (maybe there’s soap in baro holes?) or snow / water?

or jacket sleeves
-
@Tadas-Linge I think the deviations you are seeing are not acceptable. I would contact support. Prior to that, have you attempted a hard reset on the watch?
-
@Łukasz-Szmigiel hello, in the first half of run there was light rain, but then sunny till the end. I doubt that something could go in those small holes…but you nevet know
-
@sartoric hello, no jacket sleeve is locked with velcro lock above watch
-
@Brad_Olwin hello, no, i have not done any kind of reset. I will try to do it now. Thanks
-
@Tadas-Linge It will remove all custom sport modes and data, you will be starting fresh so if you have custom sport modes take screenshots so you can easily restore them.

to my knowledge if you remove the track from SA instead of disabling it and sync the watch you can no longer remove it from the watch (for now)
please mods move these posts somewhere else

@Brad_Olwin hello, so today i was running in snow storm, but surprisingly altimeter measuruments were better than ever. I gues reset did its magic. I will make couple more trial runs to be totally sure. What is more, i am in contact with Suunto distributor here in Lithuania and they told if i am not happy with altimeter, they will give me replacement watch and will take mone for investigation. I was really surprised and very happy with such offer, and also, when they are so good for me i do not want to bother them if this is just a question of reset
-
@Tadas-Linge Keep us posted because the altimeter readings you were getting were poor. I have also had excellent service from Suunto. Glad this worked and hope that it solved the issues for you.
-
@Brad_Olwin Do you or any one know if the Baro in the SV is the same in the Race?
-
@Brad_Olwin hello,
so i have completed these 3 trial runs after hard reset. each 20 km, almost the same route. first run and the third one was same direction and second one opposite direction. unfortunately with each run altimeter readings were getting worse. and weather condition with each run was getting better. so i am totally confused here and i think i will give them to check the watch. all data in attached PDF: Suunto altitude after hard reset.pdf -
@Tadas-Linge
Looking at your pdf. Are you saying that altitude difference about 10m is something wrong?

SSU too:

@Mff73 hello, not exactly. What i see, that watch fresh after hard reset is showing really good results, but then whith each use it is getting worse.
