(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.

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…

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…

Yup same for me, using GPS+Glonass (default I think) & pretty sure my run wasn't along the middle of a river! Seems to have affected all watches as a friend in Germany who got a present of a 245 for Christmas messaged me that it seemed very flakey today. His first Garmin so thought it might have been lots of cloud and/or snow.

same here. Two activities today that both shifted some hundred meters to the west at the start and corrected halfway through the activity. As a result I got a new fastest 400m time while I was doing a recovery run.

Same here in Germany on both my 945 and my wife's 245.

Today part of my run was shifted by at least 100-150m for the first half.

I had the same issue, GPS + Galileo. Position has been moved 200-300 meters west.

I confirm it too. I checked my position on the Map. The position witch is shown is far away from my real position. I have checked with GPS+Galileo and with GPS only. I synced than with Garmin Express but the issue stays.

This is odd, too many people with issues first day of the year. My watch was way off for the first mile, like very weird course, but then it went good as usual. GPS only NYC
