Spacecraft Power System Design




John C. Logrando, Lockheed Martin Space Systems Company




The presentation is designed to illustrate the multidisciplinary issues that must be considered
     in the systems engineering of a spacecraft electrical power system. It includes a discussion of spacecraft power
     system requirements definition, design trade-offs, solar arrays, energy storage, and power conversion electronics.


The list of topics to be discussed includes:


  • Review Electrical Power System Design considerations and requirements for space.

  • Space power system conceptual/architectural design and analysis

  • Define components and selection criteria with hardware examples.

  • Packaging techniques for space environments and reusable scaleable modular design.

  • Technology updates on key electrical power subsystem components and investment areas.





John Logrando, has thirty five years of progressive direct experience in
     program and engineering design and technology management of communications and power electronics systems for
     high reliability avionics/spacecraft for commercial, civil, and military applications. In his current position,
     he is responsible for the Electrical Power Subsystems Engineering for Lockheed-Martin for products which include:
     Electronics Power Conditioners, Batteries, and Solar Arrays, Bus Regulation Components and Subsystem Design and


Past positions include directorship of the establishment of the Lockheed Martin Power Center,
     a group of 400 technical, manufacturing, and support personnel engaged in product development and technology, as
     well as standard products for spacecraft power systems, power conditioning, batteries and TWTA-HV EPC productions.
     He was also the Director of Advanced Development and Spacecraft Architecture, responsible for all IRAD and
     conceptual spacecraft design functions.


Mr. Logrando earned his B.S. in Electrical Engineering from Penn State University in 1974, and
     MBA from Shippensburg State University in 1981. He is a registered Professional Engineer, an adjunct professor at
     Mercer County Community College and College of New Jersey, and a senior member of the IEEE and an AIAA. He has
     been an IEEE/TAC/ABET program evaluator from 1989 ¨C 93 and was the Technical Chair for the AIAA 2004 Communications
     Satellite Systems Conference and invited speaker at ISCe 2004 for Military Space IR&D Panel. He is a member on the
     Virginia Tech and College of New Jersey technical advisory boards.
