Suunto 9 baro - GPS track not accurate

[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.

@TELE-HO - that looks nice

First I wanted to buy Suunto Ambit 3, a friend of mine has an Ambit 2 and never has issues with the tracks. But it’s still expensive for a 6 year old watch, which means was a very good one.

I tried Xiaomi stratos 2, good tracks - not such a good application, was too much of a smartwatch than sport watch.
I tried then Fenix 5, good tracks, problems with software/battery, even with no run and WHR stopped the battery was out in 2 days.
So I was looking at suunto spartan and suunto 9.

…and seems i have to get back to ambit 3.

@v-sacre
I have once in 1.5 years had an issue where the gps signal was totally crazy for half of the activity. After that, no bad signals ever again. Not one out of 10… never.

brand new A3 Peak

what do you mean by brand new?

[freeheeler]

@florin2528
I used to buy second hand watches and they were always quite good. But now I have decided to order a new one from a shop.

@florin2528
Maybe I’ve missed it, but did you already try a different path ?

Back to that “faulty” track, Is there any kind of electric stuff along that road (plant, pillar etc)?
Do you wear any kind of magnetic stuff near your watch.
You can’t imagine the mess …

I don’t know the true factors, there are some rumors:

• A3P has more simple components then new products, this makes its GPS has less interference.
• A3P has a GPS not under screen, it makes its GPS has less interference, (well let’s see S5?)
• A3P’s GPS (Sirfstar V) has better tune

Hi, these drops in GPS looks like you have a power saving enabled. I am here to help on this.

How does the prestart screen look like?

Also very soon comes a new GPS FW so I would encourage you to wait a TINY bit for it.

[florin2528]

@sartoric

I tried different paths and sometimes the tracks are decent. But 1 from 5 had accuracy issues.

not really, but along the road there are some 380v cables.

No magnetic stuff. I was thinking to buy this watch in order to get rid of phone.

[Dimitrios Kanellopoulos]

@florin2528 Lets solve this. Check my message above.
S9 has a good GPS reception I am sure, something is going not well with your setup

[v.sacre]

@TELE-HO When I talk of bad accuracy 1/10 times, I don’t talk about crazy things, just small off track problem like @florin2528 has reported.

[florin2528]

@Dimitrios-Kanellopoulos

Power saving is off, I didn’t consider using that option since i’m not an ultra runner.
the watch has now 71% of battery, yesterday could have like 80%.

I was waiting to get GPS signal before starting the run. I was running with phone(runtastic app, running for the oceans) and the distance between S9 and runtastic was getting bigger with every kilometer i made. I spend like 10 seconds on the finish before stopping the run, on an open space. Not visible on the track.

I can share the GPX file if you would like.

I can wait till 29 of june, last day for retuning the product back.

Thanks,
Florin

@v-sacre
yes that’s how I understood it

hold on, that’s a tricky way to confirm the new FW comes within two weeks

[Dimitrios Kanellopoulos]

@florin2528 hmmm strange to be honest. I saw the tracks and there are drop outs on the reception.
Just to confirm once more, at the prestart screen the color is green right?

[Dimitrios Kanellopoulos]

@zhang965 yeah lets give some insight to @florin2528

[zhang965]

I think his GPS lost randomly the signal, it’s why he had the straight line sometime and sometime not

[Dimitrios Kanellopoulos]

@zhang965 yup that is suspicious here.

[florin2528]

@Dimitrios-Kanellopoulos
yes, was green.
My second run with S9 was on Sibiu 10k marathon and I din’t wait for GPS to be green and start running. I didn’t get the GPS at all. Run was recorded but with no GPS. So now, I always wait.
