      @Łukasz-Szmigiel And it’s a good question. And if the answer is Yes (=> No to the second part): is there anything else that S9 might be doing that might be particularly affected by type of canopy? Anything that your S5/L-B’s TomTom Spark wouldn’t?

        Wow guys, thank you so much for trying to help me understand the problem 🙂 To be honest, I don’t know if the fusedtrack is active or disabled while being on the Performance mode. If yes, that would certainly be a good explanation.

        @Łukasz-Szmigiel I havent done the reset, just the final 2 steps. By the way, I assume you are in Poland too, what GPS mode do you find to be the most accurate?

        There is one more thing - sometimes I feel a very small, almost unnoticable watch vibration (lasting maybe a 0,5 sec) during runs but there is no message on the watch face. I was reading somewhere however, that that is the barometer

          @Lukasz-Berdowski I usually stick with galileo. In dense forests and mountains glonass is also handy. Beidou seems to give the best response (quickest to get back on track) after track accuracy degenerates but also gives me strange offsets. Also I don’t find it so good in woodlands. Generally with latest firmware, in the open, plain gps is more than enough. But the error gets pretty significant as soon as I enter wooded area so I usually use galileo - the error is there but it’s more like an offset than a zigzag.

          I’ve been also setting a description of which GNSS I use in my workouts to have a better look on it and more data.

            Fused track is 100% off on best mode.

            We had that on before the watch got into production and the results were bad because in many cases the compass is not calibrated.

            I have seen your tracks. They are not good. I also wonder why.

              There is definitely some magic going on with how watch interprets raw signals from GPS sensor which may lead to issues in rare conditions. For example, when stationary, S5/S9 doesn’t draw motion - there are no weird shapes being drawn on map (which isn’t the case with Garmins, for example, as they’re constantly drawing).

              So there must be some filtering which may be failing in certain conditions (as in this post). It’s hard to guess without knowing the actual methods Suunto is using. By analyzing my own tracks I’m guessing FusedSpeed is influencing the recording (if pace is prioritized over GPS accuracy) but it manifests itself with track offsets (that are constant until change of directions). But that’s my guess anyway.

              Also, in my experience, the longer the run, the better the path being drawn - perhaps there’s some room to optimize this behavior?

                @Łukasz-Szmigiel The “not-draw” when static is Sony magic.

                  @Dimitrios-Kanellopoulos cool. I thought it’s Suunto’s algo. So the chip doesn’t even provide raw data? It’s always processed?

                    @Łukasz-Szmigiel I am not sure about that, but I can say that the chip indeed does a lot on it’s own.

                      Hey Guys, I just did a new run, results are much better, while still not perfect, I can live with it 🙂

                      I did a soft reset, updated gps via app, waited 15 minutes, then acquired the gps signal and waited additional 3-5min.
                      The run was tracked with GPS & Galileo.

                        this one looks good.

                          @sartoric thank you, I agree. I will keep testing, nad hopefully the above mentioned process will not dissapoint 🙂

                          Also, I felt very slight singular vibrations on the watch more or less where the biggest inconsistencies are. Maybe the GPS is loosing conncetion and recconecting or something? It happens every time on this track. But there is no message being displyed

                            @Lukasz-Berdowski said in GPS bugs on Suunto9:

                            I felt very slight singular vibrations on the watch

                            Are you navigating a route ? Could be the “off route” message

                            there is also the chance that the path slightly changed compared to the satellite photo as both tomtom and s9 track it on the right (the upper left section)

                              @Lukasz-Berdowski this looks pretty ok. You can also try glonass, its satellites have different inclination than GPS and Galileo and there are (usually) more sats available than Galileo so it may also be helpful in dense forests.

                              I also wonder how will the recorded path look like if you reverse directions?

                                @Lukasz-Berdowski what hand do you wear the watch ?

                                And what’s the direction of the route I see ? Clock or counter clockwise ?

                                  @Dimitrios-Kanellopoulos I think it’s clockwise, notice the km numbers.

                                    Left hand and the direction is clockwise. There is no track navigation on. When I look at the menu, there is ‘breadcrumbs’ selected.
                                    I will try to run the other direction next time, I am very curious about the result 🙂

                                      @Lukasz-Berdowski or just chnage hands.

                                      If you are doing clockwise and left hand then if you also are more close to the left part of the road (typically you ain’t you are right for clockwise eg pavement) it’s more blocked the signal.

                                          Hi all,

                                          Just to add my touch on this topic, I’m pretty happy with my Suunto 9 baro but every time we hike with my girl friend, there is between 300 and 500m of difference with my watch and her garmin forerunner, even if we start/stop our watches at the same time and follow the exact same path.
