A Space Power Satellite capable of providing solar electric power economically for 24 hours per day has been a dream for decades. However, the SPS concept is very complex since it assumes multiple energy conversion steps and includes specially constructed ground microwave receiver stations. The 5 km by 15 km Integrated Symmetric Concentrator SPS concept employs light weight mirrors in a GEO orbit. Herein, it is proposed to use a constellation of 10 km diameter mirror arrays in a much lower sun synchronous orbit at an altitude of 1000 km deflecting sunbeams down to terrestrial solar power fields at dawn and dusk.
