Suunto 9 Baro - GPS issue

[Rben08]

Hello,

I’m using a Suunto 9 Baro since a little more than 3 years.
On daily basis, nothing to say, it’s a great watch.
But, on several occasions, i found GPS issues on races, after 100km.

Here an example :
-> I ran twice on the same trace.
The second one, suunto seems to just saving points and linked them, but without having any impact on distance / D+.
On the same bit of road, first one made more than 3km, second one less than 200m.
I was thinking fuzetrack was able to manage that. But here it looks like i was teleported.
This pretty much break all my stats (more than 55km/h as max speed due to that teleportation)

I must precise, i was in a forest around 10km of the center of paris, not in a deep cave or something.
Watch was set in endurance mode, but i also saw that in performance mode.

Is there some parameters / configuration which could be turned on / off to help a bit ?
Or am i just stupid and don’t understand something ?

Please, if you have any information, it’ll be fully appreciated.

Thanks by advance !

I’m not sure if it helps.
Are all your regional available GPS modes activated in parallel?
If I remember correctly, as standard only one GPS connection type is active.
Try to turn on GLONASS or GALINEO additional, maybe you will get a better result.

@Reiner thanks for your answer !
I only had GPS activated. So i’ll try to use GPS + GALINEO.
We’ll see if trace is better next time.
