same day? what if you try to repeat that on another day?
maybe the satellite position did not like this direction change on that very spot?

I didn’t think in this way, I will try it next time
thank you a lot

@zhang965 are you using Stryd or some pod btw?

@André-Faria
this is from a cycling activity wearing a merino shirt of cigarclothing.
On the spikey HR activity I was running with a plastic shirt from https://www.cigarclothing.co/… same today: plastic shirt and spikey HR graph…

The graphs show good results about the shirt.

[zhang965]

it’s what i noticed recently:

the GPS reception is not stable.

When I run with a given pace (4;11 m/km), during a section, the pace is dropped suddenly a lot(5;30m/km), but I will get a speed compensation after this section (3;20m/km), if I understand, it’s my S9B recalculate the distance.

normally, the recalculation is OK, it will not lost so much distance on a straight section.

But if I run faster during the section curved where the pace dropped, I’ll lost the distance, as the recalculation of distance is based on two positions. you can see in my screenshots, it looks like a shortcut.

My questions about this problem;

How my GPS reception can be lost during a such long distance (during 300m )? It supposed to be logged every 1s?

How can I check the GPS logging period? How can I check where the GPS reception lost or why it’s lost?

There is the GPS track difference between 2019 2020 2021 in the same place, same configuration

Why the GPS reception is getting worse over time?

Thanks

@zhang965 good question. Different times and different available sat?

Almost the same time

It looks I’m getting lazy over years

What is Available Sat?

[Dimitrios Kanellopoulos]

@zhang965 available satellites over your heat.

I don’t know, so far, the only thing I can tell, they follow the same steps,

I wear the HR blet, I walk about 30m (so the watch has 30m to connect to GPS) to the park before start the run,

Hi all,

Just bringing a quick answer here. On my side, the GPS is wrong almost all the time. On the map I’m always going “through” building or in the lake, on the railways. Ok I’m often starting my run from town, with buildings around but we don’t have skyscrapers here and I’m always waiting the watch is ready before starting. My 9 Baro is configured with GPS+Glonass.

I would say I know where I’m running and there is no need for me to re-check the map after but there is a serious lack or precision here

[Richard Thygesen]

@darxmurf perhaps not related but my track is always wrong on the graphic map but fairly good on the real satellite map. But it had almost more or less been wrong. The last days it has been better and the only thing I changed is that I use a Polar H9 instead of a Polar OH1.

The SUNTO 9/Baro GPS is not so bad …

For the fun of it, I created a personalized “Motorsport” mooing the lawn view for when I’m cutting my garden grass …
I was impressed by the result (not the garden … but the capture of information …
It is not a 400 m stadium … still I’m almost able to see that I went everywhere … just one time I entered in the house with the mower

I don’t get you, do you understand what we discussed?

it looks like you need even more sleep now
the track from 2019 is better than the one from 2021 even with GPS improvement updates
I don’t really have something to compare like you do, because I do sports infrequently. Hence no comparison over years for the same tracks at the same time… but what I do notice is that during an activity the GPS precision sometimes is better and sometimes worse but independently from the tree coverage and without steep hills near me. I don’t see a pattern

[cosme.costa]

I think that also depends on the device, even being the same model, how it is worn and activity speed.

Here two examples, the nice track is from my running partner. He was using an S9B Ti and I the regular S9B. He wears the the watch on the right arm and I on the left. The hill was around 400 m long with 100 m ascent, and he is much faster than me doing downhills and a little bit faster than me in the uphills.

[freeheeler]

@cosmecosta
and the activities were on the same time and day?
at least the alti graph looks alright… but something seems to be always going on… either track or alti
I went downhill running today at sealevel, a loop starting and ending on our campsite

[cosme.costa]

@freeheeler Yeah, the activities were the same day and time, we were running together.

I’m not complaining, these things happen, and I can imagine is a combination of the technology itself and the watch design (hard and soft)

Regarding altitude mismatch in loops I tend to believe that this is because we do no let/give time to the GPS/fusialti do its magic, I mean we wait for the green arrow and then we hit start.

The good thing that my friend uses the same watch is that I can compare both watches and regarding altitude we are always very similar, within 10 m difference of ascent but I aslo can say that rarely we are quite off, then usually we have different altitudes at the starting point.

[freeheeler]

@cosmecosta
before I started my “downhill” running activity, I’ve waited around 15mins after the first satellite lock. The reason was, it locked but immediately lost the satellites again. It was a show of around 5min, lock-lost-lock etc… after that I wanted to see that the sats stay locked.

Pace dropped to 10m/km
