Recently we have prototyped electronic systems and effects, conducted hardware-in-the-loop testing of tactically relevant payloads with surrogate threat systems, developed RF subsystems for satellites, and analyzed spacecraft mission dynamics, environments, and resiliency. Activities may include power electronics and/or RF design, hardware development and debugging, leading teams of test engineers, specialists, and technicians, integration and test, test automation, data analysis, and documentation (schematics, interconnects, board layout, performance, etc.).
