Abstract
A method of estimating a course of an aircraft includes: receiving a time series of location data indicating a plurality of locations along a route take by an aircraft; defining a trajectory function for representing a path of the aircraft; fitting the trajectory function to at least a portion of the time series; defining a position that identifies the location of the aircraft along the route; projecting the defined position onto the trajectory function; and estimating a course of the aircraft as being a tangent of the trajectory function at the projected defined position.
