CASSIOPeiA – A New SPS Concept

Ian Cash, of SICA Design Ltd, presented a new Solar Power Satellite (SPS) concept during the Space Solar Power Workshop of the IEEE WiSEE conference held in Montreal last month. Ian’s presentation is linked below. Special thanks to Elisa Shebaro of PowerSOL, who attended this conference and brought the CASSIOPeiA presentation to my attention.

The CASSIOPeiA Solar Power Satellite is “based on the principle of wavelength-scale modular integration of all major functions, from solar collection through to beam-formation.” With no moving parts, CASSIOPeiA’s patent-pending phased array permits beam steering through 360 degrees.

The ultralight helical structure maintains a constant solar collecting area directly facing the Sun. Stowed as an integrated and highly compact package, this concept offers “the enticing possibility of a fully functional SPS deployed as a single payload.” The full CASSIOPeiA white paper can be read here.

Dr. Seyed (Reza) A. Zekavat, Michigan Tech, and Darel Preble, Space Solar Power Institute, Georgia Tech, co-chair the Space Solar Power Workshop as part of the annual IEEE WiSEE Conference. Papers and presentations from recent Space Solar Power Workshops can be seen at the bottom of Dr. Zekavat’s faculty page, here.
