Optimum filtering of the coordinates of a mobile object
Abstract
A problem of practical importance is the determination of the coordinates regarding the location of a mobile object on the basis of signals from synchronized radiation sources, the positions of which are known. Examples for such problems are related to radio navigation systems, satellite navigation systems of the Navstar type, and communication systems of the type JTIDS. Three different approaches exist for determining the coordinates of the mobile object. The present investigation is concerned with questions regarding the characteristics and the relative advantages of the approaches for the determination of these coordinates. The problem regarding the optimal determination of the coordinates of the mobile object is considered, taking into account the use of methods of the Markov theory of nonlinear filtering. Attention is given to details concerning the formulation of the problem, the characteristics of the processing algorithm, and the obtainable accuracy.
