[image-51]Mr. Dennehy currently serves as the NASA Technical Fellow for Guidance, Navigation and Control (GN&C).
Mr. Dennehy joined NASA in 2000 as the Assistant Chief for Technology for the Guidance, Navigation and Control Division at the Goddard Space Flight Center in Greenbelt, Maryland. In this capacity he was responsible for leading multiple GN&C technology developments needed to enable Goddard's future Earth and Space science missions. Mr. Dennehy planned and directed a varied portfolio of technology developments that included disturbance rejection systems, miniaturized sensor/actuator avionics for Microsat mission applications, and the common GN&C elements needed for both multi-spacecraft precision formation flight and for space platform rendezvous. Prior to being assigned to the NESC, Mr. Dennehy was the Assistant Chief for Technology for the Mission Engineering & Systems Analysis Division and he served as the Lead Exploration Technologist within Goddard's Exploration Systems Office.
Mr. Dennehy has over 25 years experience in the design, development, integration and operation of GN&C systems for communications, national security, remote sensing and scientific platform applications. Prior to joining NASA, Mr. Dennehy held engineering and management positions with several aerospace industry organizations including TASC, Fairchild Space Company, EOSAT, and the Charles Stark Draper Laboratory. He is the primary author or co-author of over twenty technical publications in the GN&C, space systems and technology areas. His principal areas of expertise and interest include spacecraft attitude determination and control system design, space platform Controls-Structures Interaction modeling, simulation and analysis, MEMS inertial sensors and the infusion of technology into NASA's future Science and Exploration missions.
Mr. Dennehy received a B.S. degree in Mechanical Engineering from the University of Massachusetts at Amherst and the S.M. degree in Aeronautics and Astronautics from the Massachusetts Institute of Technology.
