This is the GPS telemetry generated by a 10 km run in south London, with minimum tree cover/building interference (GPS + Glonass). This particular activity was preceded and succeeded by shorter "warmup" and "cooldown" activities that did not generate any abnormal data. https://connect.garmin.com/modern/activity/2877658191 It looks as though I had been flying all over London at breakneck speeds in a helicopter. I had not. Has anybody encountered anything similar with the F5X plus? I have only had it for five weeks, and so far, this is the only GPS aberration…
Check in settings->sytem->GPS if you are on 1s recording and not on "smart". You have to choose 1s for better results.
I also had some bad results too with the GPS, see other posts. It seems Garmin changed their chipset on the Fenix 5X plus and also the firmware and they release it without making serious tests. Maybe it will be resolved in future version but at this point, the Fenix 5X plus is one of the worst GPS watch !! Galileo does not bring anything else, I think it is not implemented on the watch, it is just marketing.
No, I always use "every second recording". And in all fairness, I think that this chipset is an improvement on the one used in the Fenix 5x. But this is more than the occasional aberrant GPS data point: some of the points it is picking up are literally dozens of kilometres away from reality. One might almost be forgiven for thinking that something was amiss with the satellites (both sets: GPS and Galileo/Glonass) in the skies above us...
Also welcome to the people having the running dynamics data missing after 2:08.... a current workaround for this issue is to disable bluetooth connection to the phone during the run.
By looking at your activity there is something else going on here. Are you using a HRM-Run or HRM-Tri Strap or something else with running dynamics? Is the smartphone connected? There is an issue with recording running dynamics data from these straps and having your smartphone connected to the watch. It drops recording after 2 min or so. (discussed in other threads)
After that, I see a lot of drops in the HR recording that in itself has nothing to do with the GPS (my theory). But perhaps the watch was struggling the entire run with something that caused some systems such as the GPS recording to fail. I would try a soft reset (not factory reset) and try again. If no help, I am confident that this is a SW issue and will be resolved. (ref the smartphone connection issue.)
falconeye75 I feel I get a better trail recording using "Smart" instead of "Every second", when doing "slow" activities. The GPS fix seem to jump around more when using every second. (but not as extreme as in the opening post.) Also We must not forget that Galileo is not fully operational yet and has not reached its full potential. Garmin has added support for it. That is a good thing. No?

Jimoestmann : I tries with smart before but It was jumping from side to side. It seems a little better when I set to 1 second, but without comparaison to my others GPS watches.
For Galileo, yes it's a good news they implemented it, but I am sure it is either bad implemented or not implemented. I always have about 4 Galileo sat above me so I should have better results than with GPS alone but It does not bring anything. Galileo is also more adpated for urban canyon than GPS.
I did a walk today to double check my notion of which is the best recording settings ( smart or every second ) for slower activities such as walking.
The picture attached, shows me doing 2 rounds of a local park (one round = 1.1 km). The red line is with smart and the blue with every sec. Every sec-setting gives a more precise track around heavy trees (see SW corner) but at the same time a less straight track. (I don't know what happened at the East section, but both settings had problems here. There are lots of heavy tall trees that probably messed up the GPS reception.) Anyway, I'm happy enough with both tracking results.
Looking then at the Speed and HR data one clearly see the benefit of tracking HR with 1 sec setting. (I used here the built in OHR and not a chest strap as I normally do). But I can't quite explain the continuous sine wave-like change in speed. Does it have something to do with the watch changing which satellites it uses for GPS fix? One satellite jumping in and out affecting the GPS fix?
My conclusion for myself is that I'll keep smart setting for the type of activities I do. This due to the larger amount of storage data the activity would require and the bigger battery drain. GPS tracking results alone does not make me partial to either setting.ciq.forums.garmin.com/.../1380103.jpg
