1. A method of operation of a navigation system comprising:

  • receiving acceleration information, including an acceleration measurement, and location information;

    calculating a total acceleration magnitude, having a vertical acceleration magnitude and a horizontal acceleration magnitude, from the acceleration measurement;

    calculating an average velocity estimation from the location information;

    calculating an average acceleration estimation from the location information;

    calculating a component angle between the average velocity estimation and the average acceleration estimation;

    calculating a forward acceleration and a lateral acceleration with the component angle and the horizontal acceleration magnitude; and

    generating a motion classification for a travel acceleration based on the forward acceleration and the lateral acceleration for displaying on a device.
