Abstract

A secondary UAV flies over the solar-powered UAV at night and illuminates the solar-powered UAV's solar panels to help supplement the solar-powered UAV's battery charge mid-flight. The secondary UAV could be equipped with a directional light source for providing light of a color and intensity selected for optimal absorption by the solar cells of the solar-powered UAV. As the secondary UAV flies over the solar-powered UAV, the secondary UAV could thus direct its light source at the solar-powered UAV for absorption by the solar cells, to help supplement the solar-powered UAV's battery charge. Further, the secondary UAV could potentially recharge multiple solar-powered UAVs during a single nighttime mission.
