Speed Bug using ANT+/GPS Sensor and Velo Hero!

[fidelcastro54]

Hi Orux!

I'm having a courious problem. Sometimes my Galaxy S4, which is only for Cycling and blank from Apps, gives me some stupid Speeds. Today the Speed says that it's over 1000 km/h if I send it to VeloHero. The Top Speed in the OM Statistics is 38,74 km/h. If i check the gpx File in GPS-Track-Analyse.NET i see, that there's a value at ID 1038 at 1:58:54 called v H GPS (km/h) 341,33 and v (km/h) 19,95. What am i doing wrong? You can check the Route http://app.velohero.com/activity/1220225?key=4MIo6i4H1pC11PUKZBKf">here.



Thx for the Help

Hello;



Sure it is a error with the GPS.



When you upload the gpx to velo hero, the server calculates the speed measuring distance/elapse time between each two track positions.



OruxMaps uses a different way to calculate the speed, because of the problems of innaccuracy of GPSs.

Is there a chance to fix it or do i have to edit it manually at velo hero?
