For a car / motorcycle use the frequency of GPs of the Hero6 Black (and of the others camera)is also important (on phone it is 1 Hz -once per second-) does anyone have a weblink for gopro specifications ?
And as written above by Danielr15 I was advised to turn off the information from Galileo(European Union system) and GLONASS (Soviet army system). Does it mean that my phone is using those system and my GoPro isn't ?
Any comment will be helpful !!!

A couple of things to clear up.
The GPS unit is a U-Blox M8 GNSS standard grade UBX-M8030
21 mA @ 3.0 V (Continuous)
5.3 mA @ 3.0 V (PSM, 1 Hz)
The GPS unit does have the capability of picking up GLONASS, Galileo, and GPS. I suggest turning off GLONASS and Galileo on the app because it can lead to false estimates. If you are getting 9 or more satellites with these turned off, you are much more likely to get accurate data.
What your phone uses for GPS is completely dependent upon what GPS chip is used by the manufacturer. However, location service on a phone is much different than on your GoPro. Phones are able to use cell towers to triangulate position. They do not solely depend upon GPS satellites.

I have made a reset to factory settings to my Hero6 black
I have taken my car for a short film
Back home I have used the GoPro app
(Of course I was obliged to re appaired my camera)
The result was :
First 40 meters (I have a STop signal) were accurate (speed = 0 when I stop)
But 3 kilometer away for the second stop my speed as seen afron GPS data was 30 km/h and after in order to climb to the highway I have a curve where I drive below 50 and the given speed was 80 ! Of course it is wrong but ....
I had an idea, of course it is wrong for That moment but of course after on the motorway I was at 80 (when speeding)
Thus my idea is
I am filming at 1080 50 fps in PAL
Why not try 1080 60 fps NTSC (never twice the same color) ?
Maybe the GPS will be ok and synchronized with that frequency ?
Any other suggestions ?
Of course later I will try the Manuel update as explained in the first post

Am I the only one using GPS data for controlling my speed ;-) ??????
For your information, it looks more accurate when filmed in NTSC 1080 60 fps
When I stop my car the speed is 0
When filmed in PAL 50 fps it seems strange/ not accurate ..
