Example from Garmin groups. Looks like sony chips are affected. Join the conversation at facebook if you like here

Please all reboot the watch via 12 upper button(s) to wipe the cache.
Looks like sony had some cache issue.

I double checked my activity. It is to the spot accurate, except for the first few meters where the track is anywhere fantasizing.Will do the 12s reboot

No idea if someone is interested, but I found this little clean app for GNSS information:

@surfboomerang @TELE-HO Used it happily for a while now. If you can be bothered, you can play around with the AR view to check sky mask and decide which GNSS to blame for any inaccuracy you are experiencing at that specific moment. Very minor Japanese geo-bias: if you set up your current location manually, the default first “Europe” location is Vladivostok. Nerdy fun.

New year new run nr 2. Absolutely unacceptable gps today too. Blue line supposed to be the track. No update on the s9b and reset yesterday
-
Reset the watch, but now can’t update AGPS. Neither with SA nor SL…
-
@Stefan-Kersting did you reboot the watch as mentioned ?
-
Restarted the watch and todays 43km ride was good from the GPS side.
-
@Dimitrios-Kanellopoulos yes rebooted my s9b yesterday with the upper button
-
Had problems with erroneous tracks for two days (even flagged on Strava). Now rebooted: Thank you @Dimitrios-Kanellopoulos and best wishes for a safe and successful 2021!
-
Same problems today, all day.
-
@Matjaz-Cvetko it is the problem on the Sony side, just put the watch outside and leave it there for some time on start screen…

@nseslija THX for tip.

So I restarted my watch yesterday evening, got the 1/1/2021 AGPS file. Today I didn’t get the update, went for a short hike (made short by a storm coming in), got GPS signal in a couple of seconds. Because I was following a route it was clear there were issues still.
In red the track (from Runalyze), in black the real path. After this initial mess the track was pretty good, and I could follow the route pretty easily.
-
Maybe it’s not entirely the Sony chips fault as yesterday I got strange GPS reading too with an Ambit3, but not 100% sure as here it was overcast all day long. And today my altitude reading went crazy and showed higher value then two days before in the same place, with FusedAlti on in both cases.

I just wanted to simulate this as one of my recent activities had a bad start but was to the spot accurate after a while.
Then I discovered the following: I did the soft reset. Then put the watch static (!) on our uncovered balcony after GPS lock and started an activity. I expected to see a wild curve on the breadcrumb screen… but instead:
duration: ~15min
distance: ~0.01km
ascent: 15m
descent: 3mmaybe this one is related: https://forum.suunto.com/topic/5682/suunto-9-gps-optimization-fail-wrong-altitude

Restarted the watch yesterday, no AGPS. Put the watch on the balcony for 30 min on pre-start screen. After that my ride was spot-on…
