Suunto 9 baro - GPS track not accurate

[zhang965]

and it’s why ask you to change the country…
because it seems GPS is under control in some countries? seems in Chian GPS has a beautiful random drift

@florin2528 that looks ok.
Alright I don’t know how much more to help here.

[zhang965]

for me it’s a random GPS signal lost,

this lost might be caused by weather factor, environment factor.

next time, once connected to GPS, hold on some mins to wait the connection be stable before go.

I suggest you to return your watch next Week,so that Dimitrios might release the FW quickly.

@Dimitrios-Kanellopoulos

I will have other runs and on Sunday I will change the country.
At the moment i see two options: A3 or stay with the cheap phone.

RedbullXAlps will start in a couple of days, I’m wondering if they will get the same hardware/software as me.

I used an A3S for over a year and now I have an A3R (girlfriend) at home, sorry but I don’t notice this big difference with Spartan and 9.
Above all, if we talk about precision, we cannot rely on a track recorded on a bike. The conditions are optimal there. I recorded tons of it, with SSU, of precise traces like a hot blade in butter. However, let’s see what the update of “by 29.06” will bring

You can ask @Dimitrios-Kanellopoulos

@Saketo-Nemo
ok, sorry… I can’t supply other examples as there are no mapped trackmarks for skitouring

[Dimitrios Kanellopoulos]

What is is about the xalps?

[florin2528]

@Dimitrios-Kanellopoulos
I’m watching this competition since launching, I’m a paraglider also and the accuracy of the live tracking has improved a lot on the last editions.

They are running on difficult weather conditions, on the valleys etc, and the GPS accuracy was good in general.

@Dimitrios-Kanellopoulos

my bad, the live coverage is covered by flymaster.
We can remove XAlps from this thread.

Out of topic question if you are nice to answer:

I lost 10% of battery since yesterday(22 hours) with the following setup:

• no sport
• walking, calculating the number of steps
• WHR activated
• no notification
• airplane mode ON

Would that be decent for S9?

Thanks,
Florin

[Dimitrios Kanellopoulos]

@florin2528 yes. 10 days about (extrapolated)

@Dimitrios-Kanellopoulos

I had a run on that Sunday and the track was looking pretty bad:

During the update I was in another country with poor internet so I didn’t do the update but the runs were looking ok(not as bad as home, was at the sea side):

Turned back home, made the update and I started with a run, but the GPS signal was low, mobile phone did complain about it(some clouds on the sky). Even that the s9 had a better signal than the phone which was not registering GPS at all, only time for more than 1 km.

the track was ok in general.

then I did some biking and the track was looking pretty good:

I traveled to Innsbruck and did some hiking and running.
Hiking was bad:

running was good as can be:

Now i’m back home and I will continue with another reply.

Now i got back home and did biking:
the track was looking more better than when running:

but running was ok, but not so accurate, i’m happy with it:

In general i think that from GPS point of view it’s fine.

[florin2528]

@Dimitrios-Kanellopoulos

But i noticed some issues with barometer sensor.
I did some diving, maximum one meter deep and the baro indicator was showing me -75, -50.
I don’t have the log from that. I was just viewing on the watch with no activity recorded.
Being in the see, in the water was still showing me like 12 meters above sea level with GPS active.

another issue I notice it\s with WHR, sometimes it starts really slow, and sometimes drops with no reason:

altitude in orange, HR in white.

[Dimitrios Kanellopoulos]

@florin2528 it won’t work with water.

[florin2528]

@Dimitrios-Kanellopoulos
good to know.
but being at the sea level it was still showing 12m above?

[Dimitrios Kanellopoulos]

@florin2528 hmmm. That depends. Sea level is very hard to match from GPS altitude calibration. Its too many multipath errors (Google this term).

In general 12m above sea (1m in reality) might sound much for an error but its not absolute (you see the relative error).

For example if you were at some peak of 1700m and you had 1712 it looks less of an error right? Well its really the same.

To me the device looks good.

What I wonder is how it will perform if you use Galileo.

[florin2528]

@Dimitrios-Kanellopoulos

changed the setting, i will let you know on my next run.

can i ask other questions/issues related to watch app? if not please ignore

do I have the possibility to see the smart sensor battery status on the watch(S9)? can i get notifications when battery is getting low?

any updates regarding a shortcut for connectivity on/off?
