Suunto 9 Highly inaccurate speed readings

@TELE-HO yes correct

@Dimitrios-Kanellopoulos Just a small update/test after the latest firmware update:
I exported the FIT files of two moves from Runalyze and used GPXSee to analyze the fit files. The tool has 2 ways to calculate the speed: “By distance/time” or “Recorded by device”
Unfortunately the speed with GPS only didn’t improved very much after the latest firmware update if I calculate the speed by distance/time:
If I calculate the speed by “Recorded by device” it started to look a bit better:
The move with GPS+GLONASS however looks much cleaner if the speed is recorded by distance/time. Especially the second half
Is this because of a better/stronger signal if I combine GPS+GLONASS?
So it looks like the firmware update solved the speed wobble a little bit, but not quite like the Ambit 3 Peak. The speed spikes are also visible on the watch screen during the move, so it isn’t only the FIT file.
