In today's world of air and space travel, it has become increasingly important to accurately track an object's inflight position and velocity. Typically, this is accomplished by one of either angle-only or angle-plus-range tracking methods, depending on the type of sensor used to track the object. Both methods make use of well-known Kalman filtering techniques for estimating the position and velocity of the tracked object. This invention is a method of Kalman filtering used for determining the position and velocity of a tracked object. It is apparent that there are a broad range of applications for the present invention. The method could be used to dock two space vehicles, determine the position of an airplane using radar measurements, or support a variety of other tasks where precise knowledge of the position and velocity of a tracked object is required. Although each application places specific requirements on the design of the Kalman filter, the fundamental method steps of the present invention are common to all applications. In general, the method of the present invention will improve the performance of any tracking filter.
