Cost-effective Design for Today's Missions

ATI's Satellite Design & Technology course


Share |

Summary:

    Technical Training Short On Site Course Quote

      Renewed emphasis on cost effective missions requires up-to-date knowledge of satellite technology and an in-depth understanding of the systems engineering issues. Together, these give satellite engineers and managers options in selecting lower cost approaches to building reliable spacecraft. This 3-1/2 day course covers all the important technologies needed to develop lower cost space systems. In addition to covering the traditional flight hardware disciplines, attention is given to integration and testing, software, and R&QA.

      The emphasis is on the enabling technology developments, including new space launch options that permit doing more with less in space today. Case studies and examples drawn from modern satellite missions pinpoint the key issues and tradeoffs in modern design and illustrate lessons learned from past successes and failures. Technical specialists will also find the broad perspective and system engineering viewpoint useful in communicating with other specialists to analyze design options and tradeoffs. The course notes provide an authoritative reference that focuses on proven techniques and guidelines for understanding, designing, and managing modern satellite systems.

      Eric Hoffman recently retired after 19 years as Chief Engineer of the Johns Hopkins Applied Physics Laboratory Space Department, which has designed and built 61 spacecraft. He joined APL in 1964, designing high reliability spacecraft command, communications, and navigation systems and holds several patents in this field. He has led many of APL's system and spacecraft conceptual designs. Fellow of the British Interplanetary Society, Associate Fellow of the AIAA, and coauthor of Fundamentals of Space Systems.

      Dr. Jerry Krassner has been involved in aerospace R&D for over 30 years. Over this time, he has participated in or led a variety of activities with primary technical focus on sensor systems R&D, and business focus on new concept development and marketing. He has authored over 60 research papers, served on advisory panels for DARPA and the Navy, and was a member of the US Air Force Scientific Advisory Board (for which he was awarded the USAF Civilian Exemplary Service Award). Jerry was a founding member, and past Chairman, of the MASINT Association. Currently, he is a consultant to a National Security organization, and acting chief scientist for an office in OSD, responsible for identification and assessment of new enabling technologies. Jerry has a PhD in Physics and Astronomy from the University of Rochester.
