@_marcus_ I am not so sure what you mean

@dimitrios-kanellopoulos said in Real world data:
Just saying the the s9P is tuned for Glonass according to Sony
Interesting. Do you have more (technical) detail?
-
@surfboomerang thatâs Sony. No. Polar also has Glonass
-
In the options to choose which satellite systems to use, there is
GPS
GPS + GLONASS
GPS + GALILEO
GPS + BEIDOUWhy offering GPS only when it is a bad choice? What is the rationale?
Why records âGPS onlyâ that wobbling track?
-
@_marcus_ because the GNSS systems are dynamic systems, and what works one day in one place may not be the best another day or in another place.
-
@_marcus_
Itâs not that we offer a worse system.
Itâs just that each area serves better a gnss system.
Additionally gps only (actually itâs also qzss) offer more battery life as well.
Glonass costs more
Galileo much more sometimes
Beidou the same with gps only.I personally use glonass or beidou
Itâs not that gps ads the wobble or something. That can be various things from precision attempts to bad coverage and much more. While having a smooth line like many times the s7 or apple watch has , this is also post processing or on the fly processing of removing outliers or simplifying a track. When I talk about accuracy and precision it can get complicated. Accuracy is different from precision but I want to express perhaps detail vs no detail.
That said I strongly suggest when testing just wear both watches on the same arm and use same gnss systems. Also let them soak for gps

@Dimitrios-Kanellopoulos
This is now with GPS + GLONASS. Until the road fork I was running, afterwards âspeed hikingâ. Accuracy on hitting the gravel road is quite good (if the map is correct) but itâs still a very odd track. The track does not match my running path and I actually would expect a straighter/smoother track. Does it have an impact on the track length?
-
@_marcus_ I donât know tbh.
I would check with a reference watch. Arguably the Coros Apex pro is a very good gnss device.
There are several tools out there for this kinda analysis.

saturday morning data of my sleep were a little crazyâŚ
no measured resources and many measures of the spo2âŚ
-
@frederick-rochette oh wow.
-
Just mentioning:
S9P lost GPS Signal for 10 minutes, recorded one point, lost signal again and needed 7 minutes to record the track again. Gravel road in the woods with heavy rain, watch was not covered by a jacket.

Today I had a strange behaviour of my S9p during multisport mode.
First I was cycling for about 20 minutes, then I switched to customised running mode by long pressing the upper button (pushing my bike with one hand), wondering why the distance and duration from cycling were displayed unchanged (normally when switching the values start from zero) and only pace and HR actively changed in running mode.
Then I switched back to cycling for few seconds to make sure I had changed modes correctly and switched back to running mode, but the display remained as before. After about 2km I switched back to cycling and rode my bike, but again the distance and duration remained unchanged, only speed and HR showed current values.
My last attempt was to press manual pause and start again without finishing the complete recording, only then distance and duration continued to count.
At the end of the recording, the complete part of running was missing, the entire multisport unit consists only of cycling.
What could be the reason for this behaviour?The other days before I had no problems with multisport.

For those interested
Suunto 9 peak gps+Glonass
https://www.suunto.com/move/andrfaria640/6102dfdf6d6a6919c8c94747
Garmin 945 fw3.07 gps+glonass
https://connect.garmin.com/modern/activity/7211028776Altimetry on Garmin doesnât seem correct. I will try to calibrate/ see if there is any setting that can affect it.

Has anyone else tested pool swimming yet?
It is strange that in the logbook and in SA no total distance is shown but only intervals.
So I have to calculate the total distance manually and edit the unit in SA.
I used the basic profile with standard settings and S+ off. During the exercise I could see the total distance correctly.Is this a special issue of S9p or of the current firmware 2.16.26 in general?

@wotus do you have an sa link ?

@wotus I suppose now itâs too late you edit d the distance manually?
-
@wotus if possible on the next please try not to edit it.
-
@dimitrios-kanellopoulos Yes, the distance data field was zero like in the logbook and then I edited it.

Here are a couple quick thoughts after using mine since about mid-june:
-i love this watch! huge improvement for me over the 9, especially the weight!
-OHR is accurate for me, only within a couple beats of HR strap. Thatâs a first! One caveat: the strap has to be somewhat tight on my wrist.
-My trail runs seem to be getting longer distances than they should. For example, OCC ended up with 36mi/57.6km. Not a huge discrepancy but it should have been 56km. Similar experience in another race.
-Pool swimming has been spot on but after the last lap I give it an extra few seconds to think before ending activity. Otherwise it cuts out the last pool length for whatever reason.
-Cycling is great. I donât like using wrist watch for cycling but just tested it out for the fun of it.
-Battery life overall is much better than the 9 for me and i really appreciate the fast charging.
