Suunto 9 with the recent GPS firmware was among least accurate GPS watches in today's 25K trail race

@TELE-HO I don’t think any of those can be atm used as standalones. BEIDOU does not have good coverage in my area at least. Yes it has a few sats though.

@Dimitrios-Kanellopoulos power consumption is similar to gps+glo or gps+gal?

[Dimitrios Kanellopoulos]

@isazi yeah exactly. Some times I am like woooohooo. Look at this smoothness, and some other times -> Offset of 100m like wtf. I run with 3 S9 different constellations 10cm apart from each arm and you can clearly see who fucked up (which system)

[Dimitrios Kanellopoulos]

@Maryn Good question. I dont know. For QZSS for example the battery damage is 0 , for Gali more, and for glonass less than Gali

[Maryn]

@Dimitrios-Kanellopoulos based on your experience which is more reliable? Only GPS?

[Dimitrios Kanellopoulos]

@Maryn atm not sure. I will come back with test results. Dont want to give false hopes.

In theory GPS + GLO = Better and have not seen anything strage tbh

[Maryn]

@Dimitrios-Kanellopoulos ok, understood but better than GPS standalone?

[Egika]

ist there a good website that shows satellite coverage with the various systems and for a selectable region?

Thx!

[freeheeler]

@Egika
yes there is, I remember that either @isazi or @Dimitrios-Kanellopoulos has posted a phone app that shows live satellites of the famous (of not all?) systems…
BUT I’ve searched for it but can’t recall atm the topic and discussion…
it must have been in the S9 pro’s and con’s or in the firmware update wishlist… sorry

[Maryn]

@Egika Coros introduced similar thing directly in watch .
Maybe we can vote for such feature

[freeheeler]

@Maryn
an indicator about satellite reception quality

[Dimitrios Kanellopoulos]

@Maryn I would not like any of those features on a watch. Sure you can have those eg on the s7 its super easy to install an app todo that but even me gets 0 value…

[Dimitrios Kanellopoulos]

@Maryn and btw that “app” is already in your s9

[freeheeler]

@Dimitrios-Kanellopoulos
I just thought when you do sports at any place and the indicator (let’s say a traffic light indicator) goes to orange and you’re not happy about the recording you know already before you go next time that you could try adding either one of the other GNSS systems for that route?

…something like anger prevention

@isazi when reception is good, Galileo is scary to the point of showing me slaloming around puddles. Pretty amazing.

[isazi]

@Egika also check https://galmon.eu/

[isazi]

@Łukasz-Szmigiel yes, sometimes I get tracks in which I can see even little details, sometimes I go through buildings and jump around without a clear pattern.

[Łukasz Szmigiel]

@isazi this is also my observation and it seems very strange. I mean - shouldn’t it fallback to GPS if Galileo DOP is poor? The conditions in cases which I’m comparing are the same (low buildings, some trees, some open terrain, no hills, same location) but track quality varies dramatically from run to run. Even after checking GNSS planning (just out of plain curiosity) there’s usually around 7 - 9 sats available in total (GPS + Galileo). One run can be super precise and the other generally poor.

However, what I’ve observed is that the whole workout is either super precise or not. It doesn’t change even for long (20k) runs (during the run). Strange. Perhaps it’s related to fused track?

Out of curiosity, why not?

Found it pretty interesting that adding GLONASS on my Coros only added two visible satellites and did nothing for those it thinks are “good”. Sure there are a handful of GNSS mapping websites but is pretty slick being able to travel to a new place and seeing exactly what the watch is picking up.

TBH - I recently put my S9 back on the shelf for my A3P and Apex. GPS consistency, which had it ahead of the others, just hasn’t been there with this latest update.
