Re: How do you calibrate the altitude on a Hero 7 Black

Yes, I agree. But it should be better than 40m away from the true elevation, or it should allow you to calibrate. Adding calibration isn’t going to be that difficult in the software after all.

Re: How do you calibrate the altitude on a Hero 7 Black

GoPro will    down the road I am sure get that right? tkk them  from the Hero 5 to the hero 7 to get EIS stabilization  near perfect.

Re: How do you calibrate the altitude on a Hero 7 Black

Not for just GPS.   

 

Remember that the Earth is not a perfect sphere, and rotates.  

 

Did you read the info at the site I provided?  

 

Theoretically GoPro could allow you to input a fudge factor for your location whose number you determine.  But a straight GPS alt at sea level will not be right by itself.

Re: How do you calibrate the altitude on a Hero 7 Black

Hi - yes and thanks for the reply, and I have just managed to read the article you reference - it is a good read and explains things well.

 

I guess I am disappointed that there is no manual calibration available on the GoPro, especially since inaccuracy is a known feature.  I have had cycling GPS devices from Garmin for years now and they are also inaccurate, but not to the degree of the GoPro and they do have the ability to be calibrated and then they show good values (until maybe the ait pressure changes significantly.  For example, my 5 year old Garmin Edge 800 which I just turned on started at -50m but within 2 minutes settled at 1m - which is pretty close to reality.  I didn't need to calibrate it, but could have done so.

 

I am looking at the possibilities of using RaceRender to use the great video from the GoPro and combine it with GPS data from my cycling device.  Maybe the best option until the GoPro elevation is useful.

 

This is a really useful forum - thanks!
