AGPS from the future

[Dimitrios Kanellopoulos]

I had 22-08-2020 this morning. Doing now a reboot (that wipes out aGPS) to see whats going on

[Łukasz Szmigiel]

@Dimitrios-Kanellopoulos why is that? Is it due to time zones mismatch (ie. AGPS displaying GMT-8 or something similar)?

[Dimitrios Kanellopoulos]

@Łukasz-Szmigiel no that should not be it. The timestamp etc is sent via Sony. Suunto has little interaction there.

Other people (as I raised this as critical) on Suunto have 21.08.2020.

So it can be a glitch but I am investigating (and Suunto)

If you reboot the watch and sync via the app ?

[Łukasz Szmigiel]

@Dimitrios-Kanellopoulos hm I can soft reset but then I won’t be able to check if it’s related to this as you suspected it might be related to GPS time.

[Dimitrios Kanellopoulos]

@Łukasz-Szmigiel Good one

[Łukasz Szmigiel]

@Dimitrios-Kanellopoulos just in case, logs from today, no soft-reset, after writing this post:

[Dimitrios Kanellopoulos]

@Łukasz-Szmigiel I also did one. It was fixed. I’ll send the logs.

[Dimitrios Kanellopoulos]

@Łukasz-Szmigiel now that I remember:

Sony has done this again.

[Łukasz Szmigiel]

@Dimitrios-Kanellopoulos I’m curious what will happen tomorrow after the watch tries to get AGPS from 22nd while having 22nd in memory.

same here, agps from future

[Dimitrios Kanellopoulos]

@Łukasz-Szmigiel nothing I suppose

[Dimitrios Kanellopoulos]

Looks like it was sony.

At least our watches didn’t get "affected " aka no gps

[Łukasz Szmigiel]

@Dimitrios-Kanellopoulos interesting! I had a run today with no issues. Also the watch didn’t go boo boo as I suspected it might.

[Dimitrios Kanellopoulos]

@Łukasz-Szmigiel I have seen these glitches with the agps from sony.

[Maryn]

My gps track wasn’t as good on 21.08 as always, but it wasn’t very bad either
By the way in the last few days I run every day and observe a slight deterioration for the gps mode itself.

[Łukasz Szmigiel]

@Maryn I’m sticking with Beidou. It’s most reliable and there are plenty of satellites available, at last above Poland. And battery use isn’t bad either.

[Maryn]

I used beidou but sometimes I had a slight shift so I went back to GPS for a while. Today I will try again with Beidou

[Łukasz Szmigiel]

@Maryn I think that those shifts may be related to how the GPS chip is processing position using GNSS data and hand movement. Notice how offsets are often reset when you change direction.
