GPS Signal lost

zhang965

it depends, you should have a try,
Glonass is RU, Galileo is EU,

in France, GPS+Galileo has better performance than GPS+Glonass,
in URK, it seems GPS+Glonass is better.

I guess I will try that before getting a new watch.

until now I used ambit3ps with gps only and had quite good signals with best gps settings… yesterday I first tried gps on s9b and decided to try gps+glonass next time. I think in the mountains, when you are at a rockface or between seracs gps signal could be not excellent… maybe glonass could still help here? I’ll get my experience during winter in that kind of topography…

but maybe your watch needs a forced firmware update or something? loosing signal sounds strange

@zhang965
they all call it something with G because of global, no? not only russia and europe
but who knows with all the crazy politicians how it will be in the next year’s…

ok, good luck,

I never had problem when my S9 on Montblanc

Frederic

@TELE-HO I will definitely try GLONASS but it is strange that I loose signals in places where I have been before with my Ambit 2 and didn’t have ANY issues. As a matter of fact, sometimes my wife is with me with her ambit2 and she doesn’t lose GPS.
The other strange thing, like I mentioned in my original post is that this issue didn’t happen before 2.8.24

@zhang965 HA!

@Frederic
maybe flashing helps? I read that sometimes in other threads when the watch does not behave how it should …

Do you have a link to the instructions ?
Thanks

Glonass seems better in higher latitudes zones,
Galileo in mid-latitudes zones gets better

@Frederic
not sure if ambit and s9 work the same but this is the instruction for ambit:
Force firmware update for Windows

Connect the watch to the computer.
Right click on the Moveslink2 icon (M) on the system tray and choose “Force Firmware Update”.

Frederic

@zhang965 But Galileo is for EU right ? I am in the US (Colorado)

zhang965

but you mentioned tour du mont blanc?

@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

freeheeler

@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
