Update 2.33.16: GPS Precision

Rodrigo Lima

Since the last update 2.33.16, the GPS accuracy got a lot worse while running on the same course I always run.

@Rodrigo-Lima
did you check if agps is up to date ?

@sartoric
Yes, the AGPS is with date: 2024-05-28T00:00:00Z

Here you have pictures of the exactly same course, a good one before the update and a bad one after the last update.

Before Update:

Even the Altitude went completely wrong.

Same wrist ?
Same weather ?
Did you have always the same bad result ?

It could be just a bad gps day.
Did you try a soft reset (and sync again) ? Just don’t do it right before the run

Rodrigo Lima

@sartoric
Yes, the conditions were the same.
I never had any problems with the GPS. It was always very accurate on the GPS track until this last update came.
Both runs I did after the update, the track has problems.

Rodrigo Lima

Is there a way to revert the watch to the previous version?

@Rodrigo-Lima whaaaaaatttttt the hell

I don’t think it’s related to the last update, no GPS firmware change in that. And my Race produces just perfect GPS tracks also with the latest FW.

Rodrigo Lima

@halajos mine also used to produce perfect GPS tracks.
What could be the solution for this?

@Rodrigo-Lima you could try this:

ensure you’re using performance mode
soft reset the watch using 12s upper button press (AFAIK this clears the AGPS data cache)
sync the watch with the Suunto app to download AGPS file
wait a few minutes to ensure AGPS data is unpacked and processed by the watch
before starting the activity wait until the GPS indicator turns yellow and wait a couple of minutes more to let the watch connect to as many satellites as possible (do this preferably in an open area)
start your activity with GPS

If this consistently leads to bad GPS tracks, then your watch may be faulty.
FYI: It may happen, that an AGPS file on a given day is faulty or there’s a faulty satellite. These events are rare, though.
