A method and apparatus is disclosed that modulates the position of one target tracked by a position measuring instrument, measures the path of the target, fits the parameters of a mathematical representation of the time varying path to the path of the target measured as a function of time, and obtains the position, orientation and velocity of the object on which the apparatus is mounted. Key aspects of the modulating nest and the improved method for determining the best fit mathematical representation of the path of the target resulting from the combined effect of the modulation and the motion of the object are disclosed.
