Spacecraft Power Systems Design

2-Day Course

Summary

This two-day course provides spacecraft power systems engineers and satellite system architects with a comprehensive approach for the specification and detailed design of the power system. The impacts of the space environment and mission orbital constraints are appraised. Existing power sources and energy storage technologies are studied in depth. Technology readiness of emerging developments in power generation and storage are evaluated. Basic power system architectures and power regulation techniques are presented including power system block diagrams from flight programs. A LEO power system design example using existing design constraints is presented.
