Suunto 9 Peak GPS problems

[Steven Limmer]

I noticed the GPS signal deteriorating with my 9 Peak from October. I ran Amsterdam marathon, and the GPS was a mess, so bad that I could only count on Activity Time / HR and manual lapping. I put the issues down to racing a marathon.

However, for the weeks after it, the GPS signal was a mess on my regular home routes, to the point that I couldn’t trust pace at all, and was getting the wrong tags at end of runs. This was the reason I ended up selling, and getting a 9 Peak Pro (which has been a lot more reliable)

My experience with s9b, s9p and s9pp,

After several months use of watch, the gps quality is dropped significantly.

I don’t know if it related to the watch memory .

@Steven-Limmer

Thanks for telling your experience.
Do you think it may not be repaired in the service?

Of course, there is an option is to buy a new one and greater one , but I regard this as a last resort

And really hope that the GPS problem is not a marketing tool from Suunto)

@zhang965

Thanks a lot for the response.
I gonna check the memory.

[Steven Limmer]

@zhang965 Interesting! I never had this issue with the S9, with about 2.5 years solid use. The S9P was about 1 year old when the issues with GPS started. I’m hoping with the S9PP being a different chipset, I’ll not have major issues.

[Tieutieu]

@Steven-Limmer same for me…never had any gps quality drop in time…

with my S9B I sometimes noticed that some weather conditions (very cloudy days) could affect GPS accuracy, but slightly.

For me, either the GPS antenna works, either it doesn’t.

I don’t know what you guys are calling “memory check”.
The S9p has no “user memory available” like SV or SR (for maps storage).
“Memory” (for diary history, guides, routes…) is automaticaly managed by the S9p.

(The only way to “clear memory” would be to perfom a hard reset. Never peformed on any watches I’ve owned, except before selling or giving them to someone else).

I would more likely perfom a stop/start of the watch or a soft reset to see I what you’re experimenting still occurs.

@Tieutieu

Already restarted the watch
But that didn’t help

You need to hard reset the watch to test it.

[Swaddy61]

Just note that a hard reset will delete everything - your history, set-ups, data, the lot! Still… could be cheaper than getting a new watch!

Humm, I may be wrong, but hard resetting the watch won’t impact the Suunto App, so, you will only loose the info stored on the watch, like the journal, stored map and such, but nothing more, and nothing really impactful IMO

[Swaddy61]

@Elipsus Correct - I wasn’t so clear. A hard reset will mean you will have to set the watch up again, but as I was trying to say (badly…) - 30 mins fiddling about is a lot cheaper than a new watch!

[mrg-morozova]

@zhang965

Thanks very much.
A hard reset did work. Today’s training went without any troubles. Hope, that will work further!

What does ‘syncing a new AGPS file’ mean? How can I do that?

My watch takes very long to find a GPS signal, typically 2-4, even 5 minutes. Occasionally, but annoyingly rarely, it locks onto the GPS signal in less than 30 seconds. This is in quite an open street, not surrounded by tall buildings, at a T-shaped crossroads, so it shouldn’t be a problem, and indeed it is not for mobile phones. I was thinking the watch may be faulty, but is there something I could do? Many thanks.

[Tieutieu]

@prssn just sync your watch with the app regularly (at least 10min before any activity). This file contains satellites position informations. It helps your watch to get signal quicker

[cosme.costa]

@prssn As @Tieutieu just recommend you should sync your watch with the app often or have the phone and the watch in range to do it automatically, depending on your phone you should check that it doesn’t kill the Suunto app on the background and let it running always).

Differing on what @Tieutieu says I would sync 30 minutes before instead 10, depending on the watch it needs 10/15 minutes to deploy the AGPS file and if you try to lock the GPS without AGPS it can take 2 to 5 minutes that you comment.

This AGPS file is a daily file but you can have good GPS locks with it being 2 to 3 days old.

[prssn]

@cosme-costa @Tieutieu Thank you very much to both of you – this is very helpful. I’ll see how this works the next time aroundl.

This is the important bit: you don’t have to sync watch and app every day and before every training – every third day (or every evening when you want to look at your metrics like CTL etc.) is sufficient.
