Poor GPS Track on 7.2

Just updated to 7.2. Had a weird error similar to the shifted GPS tracks earlier this year only it happened at the end of the run?

After ~5 miles the course drifted off and never corrected.

First run made on Wednesday and everything OK

Yeah, done two road runs and one trail run, and 7.2 has been spot on for me so far. GPS + GLONASS in Michigan.

To be as precise as American friend, I only GPS from Northern Italy

After the update did you do a soft reset? And at first use after update did you let it soak for a few minutes, or make an activity by starting the watch and leave if for a couple of minutes in an open space? Then discard the “fake” activity. Then start your run or bike. My bikeride was spot on, gps plus Galileo

Done two trail runs. Both spot on.

Is there any specific reason why you're not using GLONASS?

European's better use GPS+Galileo, not GPS+GLONASS, it worsens the track a lot, but that's only my experience.

As always, it depends.
if you are running next to the airport Frankfurt (FRA), you will get a lot of deviations with the Sony Chip and Galileo. My Fenix 3 was really better with Galileo enabled in that area, the 945 was so spooky I Switched back to Glonass.

That is nonsense, there are no more Galileo satellites in the European sky than in the rest of the world. For now Galilelo is still not completely deployed and you can have poor signal anywhere on Earth. Glonass is a little bit better. You can check out live estimated coverage here: galmon.eu/.../coverage.html

My question was more about why not using either GPS+GLONASS or GPS+Galileo, rather than just plain GPS, I don't see any drawbacks to using a second constellation, so I was wondering what was the reasoning behind @Luca choice.

My only reasoning is that one thing when it works does not change : with 645 I used only GPS, with edge130 only GPS and the tracks always good, so even with 945 only GPS, I get a usual fix in about ten seconds and it consumes less battery, I don't like to charge the watch often
