@Frederic
GPS is us military, glonass russia, galileo European civil… but all work global

[Frederic]

@zhang965 Yep, I was there in vacation and was sad to struggle EVERY day for my watch to find signals. The interesting thing is that it almost always lost signal around 10am. Not sure why…

@Frederic
I’d show you my story,

My s9b GPS with galileo could work great, on a 400m track, it can be precious about +/- 1meter.

but only in the morning, my afternoon running never gets the same results.

[Frederic]

@zhang965 Wow, +/-1 meter!
I will see when I try with GLONASS. I actually don’t really care that much for very accurate precision as longs as I have a GPS track somewhat accurate

@zhang965
the early bird gets the worm…

do more receivers reduce accuracy?
do you know?
it would be horrible for big marathons

[zhang965]

@TELE-HO the paris-vervailles has 21 000 runners, it didn’t seems impact the gps precision

Hello everyone,
I’m interested how works GPS on GOOD and OK profile. I know that those profiles are less accuracy than BEST one.
Today I had small Sunday walk and I turned on walk on my watch
Here is that route:

There is around 50% of my route with quite good track and 50% which is straight line.
How long that straight line could be? When the watch will find my GPS?

@tomahawk5000 apparently you could not get a lock at some point, and you got it only after a while, thus the straight line. And because you are walking and not running, Fusedtrack does not work so the watch cannot “estimate” your track based on sensors.
To be honest, unless you need more than 24h of battery for a single activity, there is no point in changing GPS settings to something worse than the best profile.

@tomahawk5000 I do comparisons from time to time. The only way is with two watches. I wore my S7 and two S9b watches one on Performance and one on Endurance. Data are below and if I did not tell you which was Endurance vs. Performance you would have a hard time guessing. This is a hill climb I did twice so each track from each watch will have 4 lines.

@Brad_Olwin ok but what dose it means? I should go faster?
