GPS problems with my S9B
-
@basetta79 if you sync AGPS do it more than 15 minutes before you start the activity. Unpacking and making the files available takes time, so if you sync a new AGPS and then start immediately it is not available.
-
@isazi ok!
-
@isazi
the best we can do is using the watch every day and sync it every day
-
@isazi are we ok the AGPS sync only by SA ? Or it’s with suunto link ?
-
@g287-sf SA is more than enough.
-
@basetta79 this is made with power saving mode
-
@dimitrios-kanellopoulos no it wasn’t. It was in Performance mode.
Edit: at least that was what I set.
-
@basetta79 can I have a suunto app link ?
-
@dimitrios-kanellopoulos hope you can check it

@basetta79 you are correct. Its best GPS mode.
However I can see that your signal is very low. AGPS was updated 18/04/21
The signal was low from start.
I would recommend that you wait like 1-5 mins after the green arrow lock happens.
"Specifically you started with only 6 visible sats (8-12 is good ).
This can happen becasue the starting conditions were hard and youi did not wait so long.
So imagine the watch barely has a good GPS lock to start, and you enter hard terrain. Then it wont have the time to recover.
Also try GPS + Glonass.

@dimitrios-kanellopoulos believe me: yesterday I synced before the start, waited for more than 10 minute (I was waiting for a teammate ) with the hooked gps and then I started my activity. This time I was using only GPS but the previous day the situation was as bad as yesterday with the Beidou configuration. Can’t understand
Edit: this was saturday

@basetta79 Wild guess…
I noticed a lot of tree cover on the east and west side of your route where you lost signal. The on the other side is surrounded by mountains. If I look at the satellite data from yesterday morning It shows me this picture in your neighborhood:
Could it be that there are too few satellites directly above you? Most of the satellites appear low above the horizon.

I live close to mountains. The point is that previously I had an Ambit3 Vertical and later a Spartan Ultra. Both the watches never had issues. Moreover I bought the 9B 3 months ago and so a friend of mine did. He never experienced any problem with his 9B. From what you can see from your satellites map, which would be the best configuration you suggest?

@basetta79 in practice the s9 should have much better GPS than the SSU

@dimitrios-kanellopoulos I never ever had any kind of problem with the SSU. (And to be fair, I never synced before activities). It was perfect. This 9B was ok until 2 weeks ago, then the problems appeared
-
@basetta79 Maybe you can play a bit with this site to see if it gets better if you try GLONASS, GALILEO or BEIDOU at the time of your next activity
-
@dimitrios-kanellopoulos Is this because of antenna design or chip? Or both?
-
Best configuration is GPS+Beidou, from what I can see.
Later I will have a short run.
Should I soft or hard reboot the watch? -
@basetta79 Soft should be enough to clear AGPS. After that sync with SA and wait approximately 15 minutes until AGPS data is fully processed.
The watch shows the status in the GPS about page. -
