      @TELE-HO I haven’t seen those spikes with my old a3p either. Only with my s9 baro.

              @TELE-HO said in Suunto 9 Highly inaccurate speed readings:

              and just noticed that the exported link displays my highest point of 948m as ascent… 👎

              It has been like this since I can remember and I have reported this many times and nothing has happened since at least January 2019 … and I bet you all my tech gear that it has been like this longer than that. Here we are nine months later and still nothing.

                I’m glad it’s on the export file only that I actually don’t need… it’s correct for Strava…
                the pain is: when @Dimitrios-Kanellopoulos wants to see our files and asks for the shared link… he does not see what we see…
                I noticed the wrong total ascent but more mistakes could be hidden anywhere…

                  @TELE-HO I dont look at the link data. As @fejker mentioned this is pretty much an old issue.

                  With the link you provide I open the activity with the Suunto app

                        @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:
                        1.png

                        If I calculate the speed by “Recorded by device” it started to look a bit better:
                        2.png

                        The move with GPS+GLONASS however looks much cleaner if the speed is recorded by distance/time. Especially the second half
                        3.png

                        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.
