Space Systems – Subsystems Designs
This 4.5-day multi-disciplinary course provides a complete summary of the technologies needed to understand and develop spacecraft systems and instrumentation. The course presents a systems engineering approach for understanding the design and testing of spacecraft systems. The course highlights the underlying scientific and engineering foundations needed to develop space systems, as well as current practices. Case studies are used to pinpoint the key issues and trade-offs in modern design, and to illustrate the lessons learned from past successes and failures.
Space Systems I & IIare recommended for engineers, scientists, or managers who wish to broaden their perspectives and capabilities.
The emphasis will be on how today’s technology is incorporated into the planning, designing, fabrication, integration, and testing of modern space systems. Each participant will receive a complete set of notes and the award-winning textbook Space Systems written by the instructors. The textbook and course notes provide an authoritative reference that focuses on proven techniques and guidelines for understanding, designing, and managing modern space systems.

Eric Hoffman joined JHU/APL in 1964, designing high-reliability spacecraft command, communications, and navigation equipment. He recently retired as Chief Engineer of the Space Department, which has designed and built 61 spacecraft.
Robert C. Moore worked in the Digital Flight Systems Group of the APL Space Department from 1965 until his retirement in 2007. He designed electronic circuitry and embedded microprocessor systems for space flight data processing.
