Hello Antti,

I have seen it's possible to select different data to graph in Graph settings. Some of the interesting are Longitudinal and Latera Accellerations, do you know how accurate they are? I have a Qstarz 818 xt receiver.




  • Hi, the spikes are not very accurate but the "constant" acceleration should be about correct. To make them more accurate would need to do filtering to remove the spikes etc.
  • Thanks AOL.

    I have seen "consistent" values of around -1 / -1.3 G for longitudinal acceleration in the braking phase with my motorbike, does it make sense to you?

  • Should be about right I think.
