      Bringing an old topic back to life after firmware update 2.8.28…

      @Dimitrios-Kanellopoulos and @dirty-hippie
      Unfortunately the speed spikes are still not correctly filtered for my case. I did two testruns today. One with GPS only and the other one with GPS+GALILEO.

      I was driving a steady 57km/h during this run

      Below are the results:

        @surfboomerang Ok. Thanks for this.

        I will have to escalate this. I would like to know how much this can happen in other modes.

        Btw what sport mode do you use? PErhaps there is different bahaviour per sport mode?

          @Dimitrios-Kanellopoulos This time I used the sports mode “Other”, but I have seen this behaviour also with “Windsurfing”.

          I checked a move that I did yesterday. I selected the profile “Running” and had GALILEO on.

          So it looks like it happens on all sport modes, but the spikes (and dips) are greater for sports with higher speeds

              @Dimitrios-Kanellopoulos The files above are GPX exports from Runalyze.

                @surfboomerang I would prefer to look at the fit file.

                Do you have some SA link for me of the files with these issues ?

                    <Frustration mode>

                    Can someone tell me if this issue is resolved in the upcoming firmware update?
                    I did a windsurf session today on a rainy day and I had GPS+Galileo on. The picture below shows a segment of a track that is almost 100 km like this.
                    As you can see it is a horrible recording of speed!!! 😫 😫

                      I just compared my recordings from a3p to s9b within SA… s9b indeed gives a spikier graph… strange!

                          @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.

                                  SHUT UP LEGS!

                                    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.
