Electrical Power System Adaptive Design for Powered-Down Launch Satellites

Batch production and multi-satellite launches are critical techniques in the construction of internet satellite constellations. They require simplification of the interface between satellites and launch vehicles for the sake of cost control and operation process optimization in launch sites. Learning from successful practice in the field of micro-satellite development, powered-down launch technology is certain to be applied in low orbit internet constellation satellites. Compared with powered-on launch utilized in traditional large communication satellites, powered-down launch requires new analysis in satellites' power system design. This paper discussed the relevant topics.
