(Known Issue) GPS Recorded Track Shifted by FAR with Respect to the Map

Amber please add me to the case. Solution does not work for me as of 1/7/2021. Very frustrating.

I bought a Forerunner 245 almost 2 months ago.

So far, I have been extremely disappointed with its GPS functionalities compared to other Garmin products.

In the vast majority of my activities I am unable to get a GPS lock. In the few cases where the GPS becomes available, it is usually after a very long wait.

I have tried various suggested remedies such as running update cycles, rebooting, fiddling with the GPS settings; all with no effects.

Is this a general quality issue with the Forerunner 245?

No.

Usually I get a lock within 10-20 seconds. Accuracity is good for me (On known tracks which length I measured with Google maps, below 0,5% difference).

Don‘t know if your watch might have a hardware problem or maybe the GPS Assistance data is missing. Have you tried to connect the FR to Garmin Connect on PC or Mac and syncronize it? This might help to get assistance data for GPS to your watch.

Beside connecting you watch to the computer and synchronizing it to receive gps satellite data you can try different satellite settings as well: FR 245 has GPS, Gallileo and Glonass, depending on where you live you might gett better results with GPS+Gallileo or GPS+Glonass. If you search a bit on the net there are websites that track sattelite loations and can tell you exactly which one will have the best coverage in your location.

Personally, I would not play too much with that.

Default for most activities like running is „GPS & Glonass“. As those two are present worldwide and it the best tested configuration, I would just keep that. Also Galileo still has not that much Satellites. And in the end, this is just about the number of satellites that will make your positioning more reliable (but NOT more accurate, at least only to a certain degree. Better than „3 meters“ it never gets with civil devices, no matter how much satellites)

At least it is worth to try: I get better result with Galileo that Glonass. And more satellites in the case one gets no lock will always be more accurate, no lock means receiver gets a signal from to few satellites to be able to calculate the position. It is of course another story when you have enough satellites visible with either setting, but this does not seem to be an issue here.

Hi, anyone else experiencing the route map being offset when viewing in Garmin connect or Strava?

All the data is fine, even the distance but the map has been offset it looks like 100m east.

Any help?

Not sure if my issue is of the same nature, but I experienced something very similar this morning with my Fenix 6. Almost the entire GPS track of my run is shifted by about 100 meters to the east. The track corrected itself after about 8 km, shortly before fininshing the run.

That’s interesting! My run was only 5k so do you think it didn’t have time to “correct itself?”

I don't know. We cannot rule that out, but not knowing the nature of the issue it's really impossible to tell. Might be a coincidence. Or not.
