Abstract:	Recent GPS technology advancements are permitting tbe development of integrated GPS navigation systems for weapon system applications which were previously precluded due to tbe size, volume, weighs power, and cost constzaints. Technology trends toward miniaturization, improved performance, application specific integrated circuits, and bigb speed digital signal processing are discussed. Integration strategies are examined and performance benefits (e.g., responsiveness to dynamics, jamming resistance, faster acquisition) resulting from “tighter” integration architectures are traded against design risks (e.g., computational load number of filter states, maturity). improvements in weapon system effectiveness are being real&d by exploiting tbe synergism between navigation, flight management and terminal sensor/seeker systems. For example, integmted GPShertial navigators improve midcourse accuracy result.illg in decreasedkrminalbasket uncertainty, and also enhance terminal guidance through aczumte motion compensation and tbe ability to fly-wheel the system tbrougb interruptions iu the sensing process. During the development of integrated systems, system level perfom~~ce requirements established from overall mission analysis, required mission effectiveness, and threat analysis must be partitioned into subsystem aud functional (e.g., midcourse versus terminal) requirements tbrougb a series of performance versus cost analyses and trade-off evaluations, subject to constraiuts such as cost, size, volume, etc. Typical performance factors impacted by GPS aud trade-off evaluations are discussed, such as band- off errors, survivability versus probabilities, field of view versus resolution, etc. Optimization of weapon system effectiveness based on subsystem requirements allocation is examined.
