Goddard Space Flight Center Engineering Colloquium
Date: Monday, April 5, 1999
To the mantra of "Better, Cheaper and Faster" the call for "Smaller" has been added. In this current environment where size is such an important driver, what are the numerous technologies for the miniaturization of space electronics and electronics systems, especially the more cost effective ones; and how can they be implemented to develop micro instruments and satellites? First, the rationale for small and smaller electronics systems is given; then, miniaturization is discussed within the context of the end-to-end systems engineering effort. The development of miniaturized electronics systems involves complex interrelationships beyond the usual size, weight, and volume to include architecture, power, thermal, costs, manufacturability, maintainability, and other systems tradeoffs. Finally, the methodologies and technologies discussed are pulled together into a microsatellite conceptual design.
Since 1984, Ark Lew has been the Supervisor of the Electronic Systems Group at the APL Space Department. He joined APL after obtaining his BSEE (1963) and has been at the APL ever since obtaining a MSEE (1968) and a M.S.(1985) in Technical Management. He has an extensive background in the design, development and management of space flight subsystems. His experience spans the end-to-end design and development of space flight electronics from the board level to integrated onboard subsystems and includes advanced technology applicable to space and terrestrial electronics systems. He has been the lead engineer for data handling subsystems on numerous APL satellite programs for DOD and NASA. His design of the MAGSAT microprocessor based command system in 1979 was likely the first such critical microprocessor embedded subsystem flown. Advanced technologies under development include advanced packaging for miniaturizing electronics subsystem; the development of microsats; advanced onboard electronics architecture; and network communications.
