ATS-6 Parabolic Antenna for Mounting Solar Cells

Calculations are made to obtain the raw electrical power that can be generated by using an ATS-6 type deployable parabolic dish as a surface for mounting solar cells without seriously interfering with its normal function as an antenna. A minimum of a few hundred watts to a maximum of a few kilowatts are generated during the apparent course of the Sun around the spacecraft. Academically, it seems that deployable solar cell panels along with their booms can be avoided.     

Miniskirt for Dancing Spinner

An idea for use of skirts made of optical solar reflectors to concentrate solar energy on the solar cell array of geosynchronous spinning spacecraft is presented. From theoretical consideration it is predicted that the practical realization of this concept will allow significant overall cost and weight reduction of such spacecrafts.
