Suunto 9 Baro AGPS n/a

@Tieutieu said in Suunto 9 Baro AGPS n/a:

@freeheeler : I had prepared my watch few minutes before the race, and had no reason to check (It usually takes less than 20sec to get GPS signal). Discovered the signal was off when the race started
Not a big deal anyway.

… and the “mysteriously” accurate speed etc should be the (in)famous “fused speed” feature, that uses more or less all available sensors in the watch to estimate (quite nicely for me, too) speed and distance … even without GPS reception and thereby without nice track on the map.

Exactly what I tought ; had the issue during another race last September, and same “accuracy”.
Works pretty well so !

[Mouse Cruiser]

It happens again. So it’s not solved yet.

@Miš-Kan
obviously and unfortunately not… but Suunto is aware and if you wait for the satellites to be locked properly it is a minor issue IMO

[Bradleyd]

@Freeheeler, out of curiosity and true seriousness, how does a person properly “wait for GPS lock” before starting a real race? Should I start running when the race begins and press “start” on the watch when the GPS has a lock? Another alternative for a time only race ( not place ) is to stand to the side, letting others pass, until the watch is ready, then start the race and the watch at the same time.

@Bradleyd
I did “races” when I did not have a gnss watch… but to me it is obvious: you warm up and you can already put your watch in start screen. this can be around 30mins or more before the start.
I know somebody who tracks warmup and cooldown at race days, too

[isazi]

@Bradleyd the easiest way is to go to the start screen well in advance. I usually open the screen already in the waiting area.

This doesn’t mean Suunto shouldn’t solve this issue with AGPS on weekends, it’s weird and bad, but it’s a good idea anyway to go on the activity start screen in advance.

[Bradleyd]

@isazi and @freeheeler, this makes logical sense: get HR and GPS locked and confirmed well before going to the starting line.

On a side note, “fused-speed” is an unbelievably cool feature and great backup for flakey GPS.

AGPS is back this morning on my S9B

[jussim]

Ah, good to know the reason. I was wondering why it was taking unusually long to get GPS locked in recent weeks. Here’s hoping for a permanent fix soon.

[Milan Šádek]

@isazi Is it only S9 related problem? I received a GPS twice within 20-30 sec last Saturday with my S5. And yesterday, it was superfast - something like 15 sec only. Normally, I have to wait even 1+ min.

Now again: AGPS N/A

[MiniForklift]

Mine is all good right now

[freeheeler]

@MiniForklift
what time and date is your AGPS?
because mine is N/A…
but Suunto knows

[cosme.costa]

I think Suunto should start to check this issue seriously, if they aren’t. Seems that is only S9/S9B related, if I’m not mistaken S5 uses the same Sony chip so issue should come from another place.

AGPS file is valid for some days 2/3/4 days but issue here is that with a sync we loose a valid AGPS file because SA pushes an empty/corrupt file.

These small things downgrades a lot the experience with the watch, I can accept that from time to time we have this issue with the AGPS but the last months we’ve have it several times, and at least 3 weekends on a row now.

BTW, I know that I can go to the sport screen some time before, I do it but this is not the way. I not always have the time. I mean, right now I’m in the middle of the cros season, I run and my kids too, so most of the times I’m in a hurry, therefore I need that the GPS locking works, not spend my little time before the start with this. In my experience, when we don’t have AGPS file, even if we wait for the lock, if we don’t wait enough time the track will be quite bad, I guess is because the lock is done with the minimum satellites and the watch struggles a lot to keep this or acquire more satellites.

@cosme-costa
agree, mainly on the technical point that, depending on dates, a “still valid” AGPS file should be kept in case of “bad one” (if it is detectable beforehand ). In such cases, watch could :
1- keep old data
2- warn user (or SA ? ) that something is beginning to goes wrong when AGPS is about to expire.

[el2thek]

I have today’s AGPS on my 9B.

[Tieutieu]

No AGPS again for me today…
Tried to uninstall/reinstall SA (who knows ! :p) but still no AGPS file.

[cosme.costa]

@Mff73 I don’t remember well but I think that Coros tells you if the AGPS file is still valid or you need to sync the watch to get and updated one. I guess this is useful when you don’t sync the watch regularly in the case of Suunto with the background sync is not needed, but …

Same experience here with non-Sony chip Ambit3 too. Not sure what is going on with AGPS data on servers, but sometimes it’s really frustrating me.
