After being happy about the better GPS of the Epix gen2, I notice more and more prolems, the best GPS settings mode: All + Multiband has always been used in the examples described here:
I use my Epix quite intensively (Since 20.01.2022), for example when navigating while guiding mountain tours, and on some days I notice really serious dropouts in the GPS.
1.) 7.24 In this track I was in the park with my daughter. Basically, most of the track is shifted to the right, but we were only in the green area. This happened after we went through an underpass, after which there was a strong offset to the right (east), which did not correct itself until the end of the activity (type: other). Since I was traveling with my child, I didn't mess with the settings, for example changing the GPS mode, which sometimes helps (see below).
The end and start should actually be exactly on top of each other.
As you can see, the drift/offset is about 200m
2.) 7.20 As you can see, the track is on the way there, on the way back suddenly in the creek. I then had to change the GPS mode several times (e.g. to GPS only), then the location wandered around, at some point it worked again. It was a winter tour, therefore no strong slope. in the data fields was the field for GPS reception (the bar display) configured: 5 bars.
This happened after 4.5 hours on flat terrain, until then everything was correct.
3.) 7.20 Using the new option "Snow Shoe"
After I calculated a route to a poi on the watch: GPS stopped completely and the own location on the watch stopped even if we moved. The altitude changed while we were moving, while the total estimated path length (data field -> navigation) became longer and longer. We were already several km on the road and I started the navigation to the poi after about 1.5 hours, when we decided at a fork in the road to the final destination.
2 restarts did not help.
Also in the activity type "Hiking" the same problem when navigation by POI was selected. Navigation by track on the other hand worked, with the known bugs (problems with elevation profile).
The next day everything ok.
I make 5 tours per week, on which I use the navigation and there are days, there the whole thing totally freaks out, or it occurs so strange GPS dropouts, as shown in 1 and 2.
My feeling on this is: all systems + multiband is accurate, but freaks out sometimes. I plan to do more tests in the "GPS only" setting.
