COMPOSITE NAVIGATION SYSTEMS: CURRENT PROGRESS AND POTENTIAL

Abstract:	Today as in the past, research and development on advance navigation systems is being shaped by the requirements that these systems must fulfill. Systems must be capable of all-weather operation; they must be self-contained and immune to countermeasures; they must be able to operate at high math numbers; and they must be precise within "small fractions" of a per cent. In more and more cases, designers are finding that such stringent requirements cannot be met "simple" systems-radio techniques, for instance or stellar observations which are based on the use of a single physical phenomenon. By combining two or more of these simple systems the designer can greatly enhance the accuracy, reaibility, and versatility of system performance. Such systems are called hybrid or composite systems. In recent years much effort has been expended in programs aimed at improving the techniques by which hybrid or composite sytems are synthesized. In this paper I shall attempt to outline the direction of current progress, and for simplicity I shall use one composite system, teh doppler-inertial navigator, to illustrate techniques which are generally applicable to most composite systems.
