Abstract: The system and method of directed navigation using an augmented semi-active laser seeker to provide initial altitude measurement and command denotation information for rounds. Using on-board sensors and communications links between members of a swarm, numerous targets can be engaged more quickly and precisely. The LCSAL can act as 3D LIDAR where the LCSAL's spatial resolution and the associated image from the imager can be correlated to the LCSAL pixel by pixel as time of arrival. The rounds trajectory can be refined due to coupling with accurate Target ID to provide optimum command detonation for specific target types.

Abstract: The present invention relates to an improved thermal management system for a heat source, such as a high-powered electronic device.
