GPS altitude meter

the non-Baro, your experience wouldn’t really indicate a problem.)
Thanks for the answer, i will Connect Suunto! BG -
@mrony
did you set the altitude before your activity manually? -
@freeheeler i have Open the activity, waited for the Signal (~10min)! infront of That, i Sync the baro9 with the suunto-App! After That i Start the activity!
-
@mrony
was your observation a one time thing or do you observe that frequently? -
@freeheeler frequently - in every activity

@mrony
honestly, I did not notice this behaviour. It could be that FusedAlti is not correcting the altitude good enough but this should be in all directions, most likely under a Gauss bell.
I once passed by a marked point on a hike and my watch was to the spot.
Honesty again: I don’t care so much about 10 or 20m. When I look at the map and know by topography plus approximate altitude where I am, I’m fine.
But I understand disappointment.
BTW changing and windy weather does challenge FusedAlti IMHO -
@freeheeler as a rule it might not matter, but if I track with the watch - it should be reasonably accurate. When I’m at the summit, the data should be correct when the sun is shining!

@mrony Yesterday at work I take a break and look at my current altitude and decide to update it via GPS.
After few minutes the watch notify me it’s ok.
I was at -7m … I try it 3 or 4 times it vary -5m , -6m.I was close to the bigest river of France not under the sea level…
Like you 9baro. I really hope the next update will improve/correct this. -
@g287-sf i also do!! I‘ll Tell this Theme to Suunto!

@mrony
I need to mention something before this thread gets locked due to redundancy… if I climb summits that are between 2’500-3’500m I personally do not care about 10 or 20m. But maybe it’s just me?!Japanese cars by the way tend to show about 10% higher speeds.

@freeheeler It’s clearly far from just you but I have uses for that accuracy. And, as it doesn’t increase my hiking weight by too much, better to have it and not need it than …
-
@fenr1r
true, I don’t fancy going over a cliff because of bad weather and wrong values. That’s why I also do not rely too much on the watch.
But the precision still is better than a compass, altimeter and a 50’000 map

@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!

@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.
