My run from yesterday has a large offset on the way back (ran the same route back and forth). I’m using GPS+Beidou with plenty of satellites in view. S9 bug or GNSS system issue?

@halajos the last two days I had bad tracks with my S9B too. But the old Spartan Ultra was precise as always. Both with GPS and Glonass.

@pilleus no issues for me this weekend.

Same with my S9B. Spot on today with GPS only…

another masterpiece of fine artwork maybe from our friend picasso… or is it more a kandinsky?

@freeheeler Perhaps if you were faster on the uphill:). Just kidding, does not look good.

@freeheeler is this a default mode ?

@dimitrios-kanellopoulos
it is the ski touring with customized modifications.

Edit: I would think that my baro needs a baby toothbrush treatment again… but then there’s the realistic descent, if I ignore the frequent small “steps” that are most likely at spots where I stopped to wait for my wife and kids

@freeheeler but graph is plotted against distance not time, isn’t it?

I PM-ed it to you as an error popped up over and over again when I tried posting it here…

I noted something interesting, I run weekly 10k in the same place.

The mode of GPS is gps only and in performance mode with last AGPS and 15mins waiting before starting.

As the field is 400m, so normally, every km mark will be the other side of field. (400 * 2,5 = 1km)

So for the figures 2 to 6, you can see the 10km mark(or the red end mark) is close to the green begin mark.

but the first one, the GPS trace is very fine, strangely the 10km marks in 200m farther than where is should be.

My question is, where is these 200m? there is no evidence that GPS takes any shortcut,

how could it be? it means during a section where the GPS saved a speed lower than my actual speed?

zhang965

just my observation,

I did a 10k GPS only(L) and a 5k GPS + Galileo( R) today, I’m still suffering the gps speed lost issue,

I run with an almost constant speed, but during the red box area, the speed dropped a lot (4m/km to 4.46m/km)! so this makes my 8th 9th 10th kms much longer.

So I ran another 5k with GPS + galileo, in the same area, the speed less than GPS only (4 to 4,16).

anyone meets the same problem?
does anyone know the root cause?
how can we avoid this problem?

@zhang965
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

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.

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?
