Some tests show mixed results for the best GPS mode

[Luís Pinto]

@yannis-belouris I read that. We have to see more tracks when Fw is ready.

[SlaSh]

Personally I don’t care how accurate line is drawn on the map, what I care is final distance is accurate or not ps I wasn’t swimming really strange drift, as almost all track is spot on.

Which watch did you use to get this?

[SlaSh]

@yannis-belouris baro stealth, this happened only 2nd time. And seems glonASS is messing my tracks, as this time was enabled.

this looks like a classic reflection error btw.

@slash was the water warm

[SlaSh]

@brad_olwin don’t know, let’s ask my watch watch says 30.4c

[SlaSh]

@dimitrios-kanellopoulos reflection from what? There were no buildings and quite open area for good gps signal.

lake / river

@dimitrios-kanellopoulos even if I am above it 20m and far away 50m? Unbelievable

[Ze Stuart]

@slash only one thing to do: find out which satellites were available to you at the time, and plot their course in relation to your course, and determine if any would have been broadcasting from the right spot for a reflection error.

What @Ze-Stuart said.

I love these debates. Lets assume it like so:

The water is a mirror and the satelite sees you from that mirror. The more far away you are the wider the angle thus where the sat is.

something like so

God damn I am bad in this example.

[SlaSh]

@dimitrios-kanellopoulos personally never faced such before near the water

I do GPS testing as you know and its the biggest problem. Usually referred to multipath problem

[Dimitrios Kanellopoulos]

PErhaps this helps

big reflecting pond slash runs around

You can tell it’s a busy day…

[Brad_Olwin]

@slash Since you don’t run:)… when walking my watch generally faces outward or laterally to the side, when running I hold my arms more upright and the watch face is generally pointed to the sky. Would be interesting to see if the track is worse when the watch and arm are closest to the water.
