      Is this known issue? I read that it may be an app issue on Android but I can see it in watch also

      Are there any workaround for this?

        What watch? Is than an S9 or S9 baro? If S9 check to make sure the GPS Assist file is installed and current. Make sure that the GPS indicator is solid green before you start an exercise.

          Its just S9 without baro. How can I check GPS Assist file? I synced watch and it was running some GPS optimization. Also I am always waiting for GPS signal before starting exercise.

            Can it be caused by enabled GLONASS? Will try without it and report back

              That process should update it. You can check it in the “about” view in your watch.
              You can also try to soft reset the watch to reset the assist file, if glonass test doesn’t seem to work

                It could, I think GLONASS is best in more Northern latitudes. I see very little difference with GLONASS enabled for me and it can make my tracks look worse. I usually leave it off.

                  Ok, so it looks like altitude is definitely better without GLONASS.

                    Hey I think I know the issue. This might happen the first time you do a run when the GPS is not properly warmed up.

                    Try to wait a bit longer after the GPS lock happens.

                    This happens when the GPS chip is cold aka:

                    • Watch is reset
                    • Watch is updated
                    • Watch is rebooted
                    • Watch crashed
                    • First run with the watch.

                      @Dimitrios-Kanellopoulos Yeah I started to wait little bit more also, so it might be now just placebo effect that I disabled GLONASS. Would be good to have number of satellites or some signal status on watches before activity. But I guess I should write this to support and not here 🙂

                        @Michal-Orlík Agreed that needs to be there in a good way to ask you to wait more or let you start quickly.

                          Hi @Dimitrios-Kanellopoulos,
                          when you say first run with the watch, do you mean the very first run with the watch, or first run of the day?
                          The reason i am asking this is because, I always find my runs elevation to be way off (like 200-300 ft) than the actual elevation. I have calibrated my watch several times, but the issue remains. Looking at the elevation profile in the app, there is always a big incline or descent at the very beginning. I always wait for the GPS signal to turn green, but the problem persists. I have never tried waiting for some time after the signal turns green (although, i must say that this approach seems odd to me).
                          I am sorry if this was the wrong post to ask this question. I have asked the Suunto customer service but haven’t heard back from them yet.

                                @Ashish-Nautiyal sorry I was confused because you mentioned calibrated. What do you mean with that?

                                  @Dimitrios-Kanellopoulos Yikes. I am sorry. Yeah please ignore the compass related comment. I meant trying with GLONASS and without it. But irrespective of that i always find my elevation readings to be way off than everyone else i am running with.

                                    @Ashish-Nautiyal Do the charts/graphs look alike to others? IT is only the ascent/descent different?

                                      @Dimitrios-Kanellopoulos Yes the map looking similar to others. Only the ascent value is different.
                                      One of the reasons i posted on this topic is that I have noticed that in my ascent graph i always see a spike (increase in ascent or descent) right at the start (within a mile) of the run. So based on this discussion, i am thinking that may be my watch gps is not actually getting locked even though it shows green.

                                        @Ashish-Nautiyal no I know what it is. Do other service if you correct the ascent report a correct value for ascent?

                                        Suunto uses a ±7m filer change for non-baro devices to avoid GPS problems.

                                        Why 7? No clue I just asked.

                                        On baro devices that number is 3 meters that works quite file imo. Remember that 1m change can happen with your hand swing only for example. ITs a complicated matter but well…

                                          @Dimitrios-Kanellopoulos Yes so if i try to correct elevation in strava, it will bring it back to what i see with others (and its not that the other runners have just garmin or non-Suunto watch, some of them uses Suunto Ambit and haven’t faced any issue like mine).
                                          What you mention does makes sense, although last week for my 40mile bike ride i got a difference of 500ft (which does seems really huge). Also it just feel awkward that i have to correct elevation after every activity.

                                          I tried something different for my today’s run. The activity didn’t uploaded automatically, so i exported the .tcx file and uploaded to strava.
                                          Here is the link to my movescount and strava for the activity:
                                          http://www.movescount.com/moves/move281124895
                                          https://www.strava.com/activities/2296968004

                                          I didnt even have to correct the elevation it automatically came to what i expected it to be. There is difference of almost 200ft between what movescount and strava shows for the same activity. Does Suunto treat Ascent info different than other services?

                                            @Ashish-Nautiyal the tcx format does not contain the ascent headers neither the fit from movescount unfortunately. Suunto apps sends the correct headers. Makes sense?
