Abstract
The research trends for guided weapons are analyzed in this report with special focus on the topics of guidance, navigation, control (GNC) and imaging infrared seekers (IIR). The most prominent trend on a system level is that previously unguided weapons are equipped with guidance capability. Precision-guided capability is soon introduced to all types of weapons and those already equipped are given increased autonomy (like loitering munitions). The miniaturization of components, the capability of integrating mechanical, electronic and optical functions as well as improved computational capacity are capabilities that enable modern precision-guided weapons. The increased capability in navigation through GPS and small, robust inertial sensors is a basis for precision engagement. Independent satellite navigation systems are established and new civil and military signals added for improved accuracy, robustness and Navigational Warfare capabilities. Navigation systems based on atom interferometry are being developed and could provide a solution to high accurate navigation in difficult environments such as under water and where GPS is jammed. Increased precision can also be achieved with seekers. A current trend for seekers is that different sensors are combined to improve all weather capability and reduce sensitivity to counter measures. New types of materials can come to increase the sensitivity and reduce the cost.
