Low cost satellite constellations for nearly continuous global coverage
Nature Communications, 2020 Satellite services are fundamental to the global economy, and their design reflects a tradeoff between coverage and cost. Here, we report the discovery of two alternative 4-satellite constellations with 24- and 48-hour periods, both of which attain ...

Designing Large-Scale Constellations for the Internet of Space Things With CubeSats
IEEE Internet of Things Journal, 2021The emergence of CubeSats as a viable means for realizing satellite networks at low costs has given rise to ubiquitous cyber–physical systems spanning air, ground, and space, in what is being recognized as the Internet of Space Things (IoST).

Multidimensional constellations. II. Voronoi constellations
IEEE Journal on Selected Areas in Communications, 1989For pt.I see ibid., vol.7, no.6, p.877-92 (1989). Voronoi constellations, also called Voronoi codes are implementable N-dimensional constellations based on partitions of N-dimensional lattices ( Lambda ) that can achieve good shape gains and that are inherently suited for use with coded modulation.
