ABSTRACT:
An estimator for determining the distance of a moving vehicle to a stationary position includes the determination of actual and estimated velocities of the vehicle along a selected path. An up-dated distance estimate is established by multiplying estimated distance by the ratio of the actual velocity to the estimated velocity. The up-dated estimate is then utilized as the estimated and another up-dated distance is obtained. Iterations continue until the ratio approaches unity indicating that the estimated distance is approximately equal to the actual distance.
