Paper Abstract

W.J. Schafer Associates, Inc. has produced an interactive end-to-end model of a laser power beaming system designed to deliver electrical power from a ground based free electron laser (FEL) to a satellite. The model includes a description of pertinent FEL physics, realistic atmospheric propagation effects, photovoltaic interactions for various semiconductor materials, and satellite onboard power conditioning. A detailed orbital model with graphical output is available, which visualizes the effect of electric propulsion for orbital reboost or orbit transfer. This flexible tool has been applied to specific examples of satellite battery charging for geostationary communication satellites, as well as parametric studies of photovoltaic cell performance. Preliminary results of system wavelength/power/aperture diameter trades are presented.
