2. Space Systems - Intermediate Design
Summary
This 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 February 23-27, 2009
used to pinpoint the key issues and trade-offs in modern
design, and to illustrate the lessons learned from past Beltsville, Maryland
successes and failures.
This course provides a strong technical base for $1895 (8:30am - 4:00pm)
