Abstract
A method at a computing device for calculating a distance travelled, the method including receiving a plurality of discrete position fixes; determining a first distance travelled over the plurality of discrete position fixes by using a first calculation technique between successive discrete position fixes; determining a second distance travelled over the plurality of discrete position fixes by using a second calculation technique between successive discrete position fixes; applying a first weight to the first distance travelled and a second weight to the second distance travelled; and determining the distance travelled using a weighted average of the first distance travelled and the second distance travelled.
