The Advanced Capabilities and Technologies Group (Group 91) researches, develops, and evaluates technologies for next-generation space systems. Current areas of interest include novel orbital constellations, deployable apertures, optical and RF imaging arrays, wide-field image acquisition and processing, feature modeling and recognition, communications networks, data visualization, and decision support. The group’s programs leverage resources from across Lincoln Lab to address critical needs for DARPA, the Air Force, the Office of the Secretary of Defense, and others. Our goal is to provide new capabilities, develop their of concepts of operation, and ensure that they are resilient to disruptive technological advances.
