Suunto 9 baro - GPS track not accurate

[florin2528]

@Dimitrios-Kanellopoulos I will do the reboot today, regarding the AGPS sync, it’s done daily.
I will get back with feedback after my next run.

Do you have some numbers regarding extra battery usage if I will enable GLONASS also?

Thanks for getting back,
Florin

[Dimitrios Kanellopoulos]

@florin2528 those numbers show on your prestart screen. I think the damage is ~2h (on a 100% charge)

[florin2528]

had another run where GPS was ok, not very accurate, but ok. Today I had another run where GPS went crazy.
I’m attaching the route from telephone (galaxy A15) and the one from watch.

I’m sorry to say, but suunto9 can’t be trusted. I was in an area with small houses, nothing that can result in something like this.
I was previously using a fenix 5 and had no issue with the track(shitty battery - but that something else).

Please advise.

I’d advise you to move to another country and give it a try.

@florin2528
they both look quite off to what I am used to

[florin2528]

@zhang965 I don’t understand you, what country has to do? My cheap phone has a decent signal, why shouldn’t have the suunto 9. I had a fenix 5 which had no issues in this country.

@zhang965 has a very high sense of humour
But after first joke, he mainly explains his real thougt

[Mff73]

And surely here, he might imagine that location of your run and/or specific day GPS conditions, may not be perfect.
Btw, the straight line in your watch recording is not good

GPS is quite cranky this week. Been noticing that the tracks aren’t particularly great.

[florin2528]

@Mff73 the conditions were not perfect, a couple of thin clouds. Regarding the houses around I attached a picture.

google coordinates where it lost signal:

I still have two weeks for returning the product back. Any chances of getting a software update until then?

Thanks,

I don’t think my S9 has a good GPS track accuracy but I think mine has not same as worst as yours.

You have to do several tests to make sure where is the problem.

Do a 12s reboot and update AGPS.

Try once in same route.
Try another route (another country)
Try another day. (sunny day without thin cloud)
Try with Glonass(sometime/some countries Glonass is better than GPS)

@zhang965

Do a 12s reboot and update AGPS. - Already did that and the calibration step.

Try once in same route. - I already did that and the track was decent.
Try another route (another country) - don’t see the relevance.
Try another day. (sunny day without thin cloud) - don’t see the relevance. If my phone works in cloudy day, suunto should also.
Try with Glonass(sometime/some countries Glonass is better than GPS) - I will and get back on this thread.

Here i was in the mountains:

but this watch is used for tracking of the rebullXalps athletes. It should work also in the mountains.

an example from another run, same place.

[zhang965]

Do a 12s reboot and update AGPS. - Already did that and the calibration step.

Try once in same route. - I already did that and the track was decent. so it means your S9’s GPS could work well
Try another route (another country) - don’t see the relevance. We’d know if the bad signal relevant the route, for example another route has good GPS signal, it means on your first route, it has some unsure factors
Try another day. (sunny day without thin cloud) - don’t see the relevance. If my phone works in cloudy day, suunto should also. Yes and no, GPS watch normally has not the same accuracy as phone
Try with Glonass(sometime/some countries Glonass is better than GPS) - I will and get back on this thread.

what product would you choose if you return your S9?
I can show you here my record of an Ambit3 Peak Sapphire on a roadbike tour in a mountian zone where there are rock faces right next to the road and during that activity there was no blue sky… it was pouring down rain like out of buckets…

They get bad track as well, due to weather factors

[freeheeler]

@zhang965
the S9 is weather sensitive and the A3 isn’t?

I don’t know, maybe? my A3peak works greater than S9/Spartan ultra

[freeheeler]

@zhang965
it’s really strange… especially since Suunto says “thousands hours of testing in the toughest conditions”…
ok, it’s a new product. I believe “thousands of hours”… but A3 has proofed millions of hours…

[v.sacre]

Bad accuracy can always happen. It depends a lot of parameters such as GPS itself, weather, obstacles, speed… With my S9, I have maybe an issue 1 times out of 10 activites. Don’t forget that you are wearing a watch. Not a big GPS device with bigger antennae.
