      Hi, I am new to this forum. Last week I used my Suunto 9 track and field sports mode and the GPS mess up so badly. (See the pic attached.) Can anyone help me to fix the problem? InkedScreenshot_20210217-215306_LI.jpg

        @thomas-ma We need to know how the watch was set and whether or not the AGPS was updated or not.

            @thomas-ma Nice artwork! 😁
            If you have a Suunto 9 you can find the information @Brad_Olwin asked for under settings->general->about

            My own Suunto 9 was also struggling with GPS yesterday so it’s maybe just a bad day.

                @surfboomerang Hell yeah, I experienced some bouncing in GPS signal yesterday, however there was never problem like this before.
                Interesting 🙂

                  It doesn’t really look like non accuracy, as it is really “geometrical” 🙂
                  Have you eventually transfered the same workout to another plateform to compare the representation ?
                  SA activity link or fit file may help to see what is inside (wrong data, wrong representation, raw data behind for suuntoguys).

                    Thanks all. So I followed the instruction above and switched to another GPS system to “Galileo.” Attached is the tracking map.

                    My next question is the accuracy: I ran 12.5 laps, which should end up equal to be 5k. However, the Suunto shows 5.38km. I ran on Lane 4 which is 423m per lap, and it should equal to 5.28m, I know 100m discrepancy is not huge but my friend is using another brand, Coros and his watch’s discrepancy is only 10m. We ran side by side as well.Screenshot_20210221-203740.png

                      @thomas-ma i think coros has a special feature for lap running where it averages out gps descrepancies so you get nicer track + more reliable distance.

                        @дима-мельниченко Agree. In general I am quite happy with my Suunto 9 tracking.

                        Does anyone know if there is any different GPS tracking function between “Track and Field” vs “Running” function? If no, should I just use “running” function for running at the sports ground going forward?

                          @thomas-ma I noticed running profile does not record GPS every second, but a random interval between 1-4 seconds. On road races with distance of half a marathon I noticed the watch is always spot on in distance, but on a 400m track I can imagine it cuts the corners less accurate then it should do.

                          Maybe that explains the difference.

                                    @isazi said in GPS accuracy - track and field:

                                    Interesting. Next time I will try the GPBeidou system and see if it reports better result.

                                    And you can tell from the screenshot (from Strava) my GPS is completely off track.pic.png

                                      Hi, have you tried “Track and Field” Sport mode for running on track? I can remember that I read somewhere that it (should) has some special setting for tracking running on Track. I have never tried it by myself. It just rang the bell for me, when I read your post…

                                        @thomas-ma keep in mind that the satelite overlay isnt always 1:1.

                                          Thanks. i understand it is not always 1:1.

                                          May be next time I will try the normal “running” mode while running on track and see if there is any difference.

                                            So I run another 10k using the regular run function, and here is the map from Strava. 10k should be 25 laps, but I think I ran 24 laps + 250m(?) from the map.run.png
