Abstract :
The results of the trade studies performed to select the power source for a typical surveillance satellite, as well as for compatible power-conditioning equipment, power control and distribution architecture, and energy storage components, are described. The three sources selected (a photovoltaic concentrator and two fission reactors, STAR-C and SNAP-DYN) were evaluated against all these criteria and for their compatibility with payload operation. The solar array meets all the constraints but may not meet some of the survivability requirements. The reactors are compact, but relatively heavy, and their newer, untried technology increases cost and risk. However, it appears likely that with development the STAR-C will meet the weight limits
