Losing GPS during activity

Does it usually happen when you're in that field next to the railway station?

Good catch :) 

Yes, this field is football pitch next to the railway station. And, as I said, I have problem "1 in 5 running activities" in that field. So I have a lot activities with good GPS signal in the same course.

One more bad example on the same course: https://connect.garmin.com/modern/activity/12525390662 (GPS signal lost after 1.1km). The same running activity, but tracked by the phone: https://pasteboard.co/EHvf3vCnFCYY.png

But, I can't understand, watch have correct distance and pace, but WHY it have not correct GPS path?

One more activity, but this out of the city: https://connect.garmin.com/modern/activity/12138518619 This activity have 13.1km with good signal, and then suddenly I lost GPS signal...

Hi all :) Just to put some update :) 

Last few weeks I switch settings to "data recording = every minute" just to check if there is some difference... 

I have one perfect 11km GPS signal in on trial race: https://connect.garmin.com/modern/activity/12701134226 

But my last two short runs were awful with GPS signal:

- https://connect.garmin.com/modern/activity/12869669238 The real GPS and pace tracked by some other phone app is here: https://pasteboard.co/VqJirVxb08NL.png 

- https://connect.garmin.com/modern/activity/12929763148 Again, same route tracked by phone app: https://pasteboard.co/vMIpQ25QbH7E.png

This time both gps signal and pace was bad... 

Does someone else have the same problem with FR 955?

It is really looks like a gps jams. I have the same in some areas. Have you tried run somwhere else? Whts result?
