Abstract
A method of operation of a navigation system includes: calculating a speed difference value based on a sensor speed measurement and a location speed measurement; generating a speed probability distribution with the speed difference value and the sensor speed measurement calculating a density regression based on a speed density peak of the speed probability distribution; determining a speed adjustment factor from the density regression; and calculating an adjusted sensor speed from the sensor speed measurement with the speed adjustment factor.
