@freeheeler you’re right. But maybe some people need accurate gps for other thing than sport ‍️

@g287-sf
I think before we keep this discussion going we need samples from @MRony where we can see the graph and have some fix points to indicate the deviation in altitude.
Location is most of the times spot on with my watch.

notice where I left the sidewalk and cut the corner? (counter clockwise direction).

and altitude recorded e.g. at the highest point of the ride compared to what’s stored in swiss topo maps.
I think it’s close to top notch.

Preferably with simultaneous, co-located fixes from other devices with known generally superior accuracy.

Ha! Good point. (Altho’, as detailed elsewhere, my A3P [FusedAlti] was outclassed by an SSU [Baro only] in a comparison a while back. So it may not be at its best.)

However, as long as there is postal delivery and selfless dedication to the scientific method …

It occurs to me that there is a more definitive test: against another 9Baro of known, recently-demonstrated accuracy.

You can fall back in affection with your Airboss in the interim.

@freeheeler today i was a Tour, and the gps failed~ 100m! Photo i will load up in 3houers!

[freeheeler]

@mrony
let’s say, without knowing details, the altitude was wrong… not GPS failed. at least that’s what I understand from the context, it could be misleading.
I’m curious about your details.

All that is really needed is to get a fit file and compare corrections in Runalyze

[Fenr1r]

@brad_olwin Will that tell you the GNSS reception conditions for the route or the corrections made for a notionally optimum route?

@freeheeler - Now I have attached the pictures --------------------------------------------

@freeheeler – one more

@mrony
PTE 5.0, are you running with your skis??

The pics are nice and the data, but it would be good if we could associate the info better.
@Brad_Olwin mentioned runalyze, but I don’t use that, hence, no idea about that one.
If you would upload to QS and share the link it would help to see if there are unregularities in the graph.

@mrony

1. is 14m too high
2. 90m too low
3. 11m too high
   correct?

[MRony]

@freeheeler correct

[freeheeler]

@mrony
personally I would only worry about the 90m low.
let’s look at your 90m low activity isolated in quantified-self.io

[MRony]

@freeheeler -
My father-in-law - always makes sure that I work up a sweat.

What means QS an how i do this?

[freeheeler]

@mrony
you can upload exported activities to here… or do a complete sync, publish, share… if you’re concerned about privacy make it private again after we checked

@freeheeler i will try this tomorow - now i musst bring my kids to bed. Thanke you for your support. KR Rony

@freeheeler Hello, I spoke to Suunto Customer Service. There I was informed that a deviation of 1-3m would be normal (would also suit me) - my deviations (values) are too high. I should reset the clock to factory settings (test again) - if that doesn’t help, i shoud send it to customer service. Info will follow! BR Rony
