摘要

Low-Earth-Orbit (LEO) satellite constellations have been demonstrated as a ground breaking technology for providing low-cost low-latency global internet access. However, each satellite needs more than 200kg launch mass due to bulky wireless components and solar cells, which raises a serious cost issue. One possible solution is further minimizing satellite mass, such as cube satellites, by realizin...
