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

[Dimitrios Kanellopoulos]

@Łukasz-Szmigiel FYI that is not stable nor something a normal person would benefit from.

As soon, and as across countries and continents, we can pass several tests we can say that it’s a safe FW to go ahead with.

@isazi now that you’ve mentioned, I also had one of the best GPS tracks this last weekend while hiking… with GLONASS although…

Perhaps if posting here we can revive mr SilventVoyager

I can share that the latest FW for the Sony chip on both S9/S5 performs oustanding.

Regarding distance, I always get more than Stryd , road or trail. Personal. But about 0.05-0.15 to A3

Can’t wait.
Are the speed spikes/wobbles also fixed on higher speeds? It got way better in the current firmware, but there is room for improvement as it still fails sometimes

[Łukasz Szmigiel]

@Dimitrios-Kanellopoulos always good to hear that new firmware is being tested and its results are promising. Awesome!

I can confirm way @Dimitrios-Kanellopoulos as I have been Field-testing the new firmware. We both agree the GPS is much better.

[azeanic]

Can confirm the latest GPS firmware is a lot better than previous iterations. I’m using Stryd for distance, so not sure about actual distance accuracy. But tracks are a lot cleaner and closer to where I’m actually running.

[Dimitrios Kanellopoulos]

@surfboomerang I have not tested high speeds. Only up to 22km/h that is the fastest j can run.

[Maryn]

@Dimitrios-Kanellopoulos let’s hope that this version stays as a release canditate.

[surfboomerang]

@Dimitrios-Kanellopoulos I haven’t seen the speed wobbles in my running activities. Only on other profiles. I think it has something to do with a different log algorithm in the running profiles.

[Dimitrios Kanellopoulos]

@surfboomerang we don’t use anything different (algo) between types.

It can be though the way you use your arms

@Dimitrios-Kanellopoulos
like “shocks” from waves and fusedspeed becomes confusedspeed?

[Shrek3k]

I am ready for an improved GPS (+ ×) software, too.
I a challenging environment (weekdays I am running in Berlin, approx 30% of the route(s) between rather solid and high houses) pure GPS and/or GPS+ Galileo/Glonass are quite often a real disaster and only offering a ‘wobbling’ track. And it does not even help to activate the exercise type and wait for a few minutes after the position has been found(yes, minutes, which currently is not too cozy )

Bravo. Better than any Friday deserves.

[Dimitrios Kanellopoulos]

@TELE-HO GPS no. Speed distance yes though Only if GPS is off / lost / bad.

There is also confusedTrack BTW

[nseslija]

@Dimitrios-Kanellopoulos Interesting, I was convinced that there is different GPS algo for different sport modes… open water and cycling, for example…

[Dimitrios Kanellopoulos]

@nseslija well I said something wrong.

For cycling/running no diff.

For open water only yes there is a special mode.

[nseslija]

@Dimitrios-Kanellopoulos ok, tnx

Can you share this FW? I take all responsibility myself if anything goes wrong.

[Dimitrios Kanellopoulos]

@zvonejan if it was with only the GPS FW updated yes.

Unfortunately it’s debug build and I can’t. Let aside that they check FW versions vs SN

[Łukasz Szmigiel]

What can I say - if conditions are right, Suunto 5 is spot on. Apparently two layers of longsleeve covering the watch don’t do much if GNSS signal is strong.

But - according to Trimble GNSS Planning there were between 8 and 9 GPS satellites visible and between 6 and 7 Galileo satellites and DOP was very low.

Today’s run with GPS + Galileo:

Open area:
Notice top right path being off - I actually run off the embankment and the track is very accurate and consistent.
