(Known Issue) GPS accuracy on Jan 01 2021?

Just had a run with my 945. GPS was way off during the run, I mean about 50-100 meters off reality during the whole route.

Has anyone else had this today? Using GPS+Glonass setting.

I have done a few more experiments and think I have worked out what is going on.

Before going for a run today I connected to GC on my PC and did a sync. I verified the CPE had downloaded correctly by checking…

Not impacting everyone, but it is a system-wide issue impacting multiple device types, not only Garmin devices.

I've just done some work today, and you can take the GPX file and make a manual adjustment to the lon / lat and correct it.

It would be too labour intensive, so I made a small python file to make the…

Same here using Gallileo in Spain, I started the run at the road with the dead end roundabout and I didn't run into the sea I ran around the peer where it says costa del sol so the shape is correct.

The same problem today. I have found out CPE is expired. I guess this is the reason why it is not working as expected. I have check, CPE.BIN file have current date and time.

There's the same issue with 'CPE Expired' being noticed over on the Fenix 6 forum https://forums.garmin.com/outdoor-recreation/outdoor-recreation/f/fenix-6-series/250026/gps-accuracy. Until Garmin fix this, you may just need to wait still for a couple of minutes (to get a strong GPS fix) before starting an activity, so the watch can receive the data from the satellites that it would otherwise already have from the CPE file.

I just tried that (until the watch wanted to go to energy saving mode), CPE is still expired.

Same problem for me running today. First 5km way off my real route. After 5km everything seems to be OK as last year. I am using GPS + Glonass (Spain).

Same issue with my fr945. Did a virtual 5k race. The track is shifted by around 300m west - so no Strava segments matched.

Same with warm-up and cool down activities. The training on dec, 31st was correct.

The shape of track is right, but does not match streets. GPS+Glonass (default running setting) active

Tried today GPS, GPS+Glonass, GPS+Galileo, no difference, when the GPS went green it was off like it used to be.

On another note, 935 with MediaTek chipset is working...
