GPS normal?

[isazi]

@andré-faria said in GPS normal?:

And which one is closer to real value of ascent?
On my experience some Garmins if they have the continuous altimeter calibration on produce higher ascent numbers.

Always difficult to judge, it depends on terrain and the definition of ascent (that may seem straightforward, but it is not).

The S9 baro and peak have issues (currently) with hilly terrain, while they perform very well in continuous uphill/downhill. The ascent/descent algorithm is being worked on, and current testing shows very good results, without making it too sensitive.

Truth is often in the middle, e.g. running on very flat terrain in Amsterdam Suunto often gives me 0 ascent/descent, while Garmin gives me tens of meters of up and down that do not exist.

@theguyfromthesummit that looks like a pretty terrible track, and it also looks like there was no GNSS signal at all in multiple points. In my experience the S9 baro works very well in the mountains, so this is very strange. Are you on trails or climbing? Are there steep gorges around? It should really not look like that.

@isazi
The first part of the ascent looked like photo 1.

The last view meters were steeper, but actually only one side was obstructed by the peak (a bit of scrambling)
The final meters wer exposed (photo 2)
My phone had always a nice GPS connection.

@theguyfromthesummit sorry of off-topic, but which summit is that? Looks great!

[isazi]

@theguyfromthesummit it looks like I expected, the track in those conditions should not be this bad, and should not lose satellite fix

You said your watch was working better in the past. Anything changed? Do you think a hard reset (reinstalling the firmware with a clean sweep) could help?

[TheGuyFromTheSummit]

@isazi
It all started with the 2.16.26 update in June/ July. The old software worked fine and I didn’t change anything.
I give the hard reset a try and reinstall the firmware.

Thanks!

No worries:

@theguyfromthesummit I completely agree. With latest update Ive noticed too that S9 was more reliable and accurate with previous firmware.

@łukasz-szmigiel
Absolutely agree with Lukasz on this.
Haven noticed this on the S7 and on the F6xPS. I noticed sometimes my distances would be slightly out and when I check my post activity maps I noticed that I the track didn’t always have me starting at the same place. So the next time I ran I waited for the affirmation of good GPS fix, and then I went into the maps. 80% of the time your icon is on your position, but the other 20% of the time it wasn’t (was within 100m), and giving that extra bit of time 30s-60s was always enough time for it the position fix to be on your exact spot.

[Łukasz Szmigiel]

@jamie-bg I’ve seen this issue of “wait a little bit longer” on the forum that I really think a new way of informing users of GPS fix quality should be developed. Either change the threshold when the watch responds with green arrow or make an intermediate phase, like “no fix” - “ok fix” - “good fix”. You can start the workout with “ok fix” and it’ll most probably get better during first 15 minutes of workout but you can wait a little longer for it to stabilize and be good from the start.

[Djordje S]

@łukasz-szmigiel Per my opinion there is a space for improvement in S9 line firmware/features in terms of stability/accuracy. For now I would be satisifed if exisitng one could be “stabilsed”

[Jamie BG]

@łukasz-szmigiel - problem with that is people then complain that it takes too long to get a fix…In most cases on average most people don’t overly get worried with a 100m or so difference.

Can’t win either way - either complain too long - or complain not accurate enough…

[Łukasz Szmigiel]

@jamie-bg you can. Redesign slightly the GPS icon. Make it filled as it is right now for “ok fix” and add a minuscule detail for “good fix”.

Those who don’t care won’t notice and it’ll be backwards compatible but those who see the difference and for whom it matters will know what to look for.

But it’ll never get implemented as it’ll take too long to design / develop / test while bringing too little of an improvement and we all know that

[Dimitrios Kanellopoulos]

@łukasz-szmigiel yup. While I am with you I agree to what you said.

[DMytro]

@dimitrios-kanellopoulos that’s too bad
Would’ve loved such icon.

[Djordje S]

@dmytro It could be done with little effort.Simple colors on existing icon.Red-bad,amber-fair,green-good.

[Łukasz Szmigiel]

@djordje-s impossible since GPS icon is color coded according to battery mode. I’d go with a small + below the icon or small “OK”. Or maybe double arrow (like a shadow with a +3 px to the right).

[Djordje S]

@łukasz-szmigiel that is true but again traffic light system for notification is recognized and easiest for understanding

[Łukasz Szmigiel]

@djordje-s I agree. But that would deviate too much from original UI in my opinion.

[MiniForklift]

Probably too complicated but it would be useful if the GPS icon could function like a glass getting filled up. What I mean is that with no GPS the icon is just an outline, then as a fix is acquired and the GPS starts coming up to strength the icon starts to fill with colour. Once GPS is locked in and everything is good it’s completely filled and you’re alerted with a beep & vibration (as we currently are)

Hope that makes sense? Like that pic above but obviously with the GPS icon instead of a glass
