An interesting article from TrainingPeaks https://www.trainingpeaks.com/blog/how-accurate-is-your-gps-watch
Looks like a “fair” comparison to me.

@ollemelin which way were you turning? which side of the road were you on? These things will all make a difference (ie if suunto is on left and most of your turns are left, it will likely be a bit shorter than any watch worn on your right wrist).,
FWIW - I am constantly comparing watches and have found that strapping it around the palm of your hand is fairly comfortable and provides the most accurate comparison

It is, but dated. I downloaded the published manuscript. For fenix, the newest was the 3 and for Suunto newest was Spartan. No data for Sony chipset.

another study:

@zhang965 that study is also sponsored by polar.
Interestingly both studies are not updated or fair for the competition.
Imo

@Dimitrios-Kanellopoulos Thatt’s the problem with such studies, they are always outdated, never on the latest firmware and always sponsored by someone. But I have/had five of this eight watches (the Garmins and the Vantage were sold, Polar V800 and S9B are still here besides A2 & A3) and the result matches well with my experience.
The V800 is besides the A2 & A3 the watch with the most accurate GPS I ever had, the FR935 was also pretty good, then the S9B and last would I rate the F5X plus.
The Vantage went back, because of the poor navigation capabilities, the Garmins were sold because of the software issues which went worse with each update and it sucks to update every 1-2 weeks not to know if you get more fixed or more new bugs…
The V800 and A2/A3 will stay as I like them as they are
The S9B is my all day and workout watch now …

shouldn’t scientists work to uncover the truth independently from a sponsor?
I would expect that from the phd’s and bcs’s in magglingen… -

I would expect that from the phd’s and bcs’s in magglingen…I would hope so too, the only thing I can think is they donated watches? I am a publishing scientist, not in this field but it is hard for me to imagine why the study was sponsored. It is possible the sponsor paid for the salary of a student or technician. If it is peer-reviewed, which these are I trust the reviewers as they new the conflicts and assessed the data.
-
Only because some company ordered a study at a scientific organisation, this does not mean it is wrong.
Maybe the setup and boundary conditions are biased, so take these with precaution, but I would trust the result itself. -
As Bradley said it, I think it’s about the “free watches”.
The study had 3 polars vs the “rest” which the rest were just a few.

Same place, same distance, same configuration, one year later
-
@zhang965 sorry, maybe I have missed something above - what do we see here (except the obvious that the latter is better in GPS quality)? Which watch & which GPS settings for first and second picture? Thx
-
@johann-fuehrer If you see the pictures there is a timestamp, and the newer is worse than the older.

Sorry, yes! - you are right, I didn’t check this. All clear now…

@zhang965 Beidou?

@zhang965 Nice park, I’ve ran there.
I remember saw a guy running fast with two watches…

both are gps+galileo
-
@zhang965 seems consistent with my Galileo experience: when it works, it works great; when it fucks up, it does it spectacularly.
Galmon also seems to point out to recent issues with Galileo satellites.

last year, i ran a lot around of this park.
this year because of the obvious circumstance, I back to the park last month and my s9b gps got way worse than last year, sometimes I can see my speed dropping a lot even though I keep the same pace. (for example 4m/km drop to 7m/km during a while)
I don’t know what happened, does the covid affect the GPS satellites?
-
Despite me being super excited by gallileo , I never use it.
I get the same experience with most.
Either great or siiiiittt.
Beidou and glonass seem the best for me.
