GPS/GLONASS sgee update
-
@Dimitrios-Kanellopoulos iOS (I’ll add gear info to my signature
). Thanks for looking into this. -
@andrasveres do I understand correctly that iOS might not update the AGP from when you check the timestamps ?
-
@Dimitrios-Kanellopoulos Not sure what is happening, it might update bad data or other format that normaly the watch expects, don’t know. All I know is that SA updates GPS data very frequently and after the update the watch is struggling to lock at first use. I check GPS data timestamp from my watch service menu.
-
@andrasveres could it be that you sync -> AGPS is not updated asap (eg takes a 15mins) and you try to go out with broken AGPS?
Try this
-Sync AGPS via SA
- Close BT on the phone.
- Wait 30 mins
- check how long it takes to lock
-
@Dimitrios-Kanellopoulos I will try that too. However before my last run I’ve checked the GPS data timestamp (was quote recent), went to a run, after finish checked again and timestamp was the same, but GPS track was missing for the first 10-12 minutes.
Do you know or can ask what and how exactly the watch is doing after new GPS data gets uploaded to it? Not the S series but the old Ambit3. Just to be sure that deploy/unpacking GPS data is not done at first query of GPS, but right after it gets uploaded? -
@andrasveres Bot sure the pal I wish I knew
-
@Dimitrios-Kanellopoulos Yesterday I tried what you suggested and here is an interesting thing:
- checked GPS data timestemp on watch
- synced watch with SA (GPS optimization took place)
- verified GPS data timestamp on watch and it was updated with new time/date
- turned off bluetooth completely from watch (as opposed on phone only) - just to be sure I will not turn on accidentally
- waited 45 minutes
- started exercise on watch and GPS lock succeeded in just ~90 seconds
- I left bluetooth off and this morning I’ve rechecked the GPS lock process and it succeeded in ~20 seconds
Now as a conclusion since SA updates, correctly watch deploy it correctly in normal conditions, all I can think of is that somehow the watch timeout for sleep is the culprit. Let me detail why:
- I use my watch as alarm and I place it bedside (not wearing it on my hand)
- watch times out and goes to sleep
- on some movement watch wakes from sleep and SA sync kicks in and updates GPS data
- watch times out again and the deploy process is interrupted leaving undeployed data
What do you think? Could that be the explanation?
Anyway, I will test my theory somehow just to be sure. -
@andrasveres at least I like the theory
-
@andrasveres I think it might be the case. That’s was my suspicion pretty much as well
-
Okay, got some more test: letting the Ambit3 go to sleep for awhile => wake up => check SA if GPS optimization is made => let the Ambit3 timeout and go to sleep again (from ~20 to ~60 minites) => wake up the watch and verify GPS lock time. Did the test a couple of times, but every time GPS lock was under 90 seconds.
Now I’m more lost then before, all I can think of is: bad GPS data was uploaded or the distance from phone and watch was too long (~3.5 meters) and bluetooth transfer didn’t finished successfully during the 10 minute timeout of the watch. -
This morning GPS went crazy again
Yesterday afternoon all was fine, left the watch near the phone for the night. This morming before run I’ve checked GPS sgee timestamp in my watch, it wasn’t changed, but upon starting the exercise GPS had trouble finding satellites. Ended up deleting exercise after finish because of crapy data it was collected. So definitely something fishy with Suunto app GPS data sync (at least for my Ambit3).
Will do a hard reset on watch and go full cable sync from now on and will see what will happen. If this continues like this I’m afraid the watch will end up with a “farewell” ticket on it as I refuse to waste more time on this issue. -
Just a quick update: did a hard reset on watch using SuuntoLink, syncing since then only with SuuntoLink via cable, no long GPS lock time or wacky GPS tracks until now. Guess I will stick with cable sync until I see some improvement regarding “Optimizing GPS” in the release log of Suunto app.
-
Quick update again: when 1.71.0 and 1.72.0 versions came out I switched back to using Suunto app for sync and so far no issue with the GPS lock time.
Thanks Suunto devs for the fix! -
I have the impression that Suunto app version 2.0.0 (8642) doesn’t sync GPS data anymore. Last time data was updated was on 12.1.2021 (as displayed in service menu) and was done via SuuntoLink when the watch was charged. In the last two days Suunto app briefly shows the optimizing GPS, but suddenly stops without displaying any error. Does anyone experiencing this?
-
@andrasveres In the beginning of this year there were some sync troubles, but they seemed to be solved.
At the moment I don’t have any sync issues (S9B + Android) and I have also a AGPS file with today’s date. -
There is an issue that is getting a hotfix asap
the workaround is to only use GPS in GPS system setting
-
@Dimitrios-Kanellopoulos unfortunately the suggested workaround didn’t worked for me. I even reset the GPS data, but it didn’t helped. I will use SuuntoLink until Suunto app will get the hotfix. No problems
-
@dimitrios-kanellopoulos Having similar issues with S9 2.13.18 and iOS app 2.0.0. AGPS data doesnt sync unless I reboot watch. Any idea (more than ASAP-5 days) when ‘hotfix’ is coming. Thanks
-
Optimizing GPS is working again in Suunto app version 2.0.1 (8648).
Thanks @Dimitrios-Kanellopoulos and Suunto devs! -
@andrasveres said in GPS/GLONASS sgee update:

Thanks @Dimitrios-Kanellopoulos and Suunto devs!Still didn’t get it, did you do something “special”?
