This chapter introduces the developments of concept technologies needed for establishing global broadband communication and connectivity using satellite constellations at different orbits. Each satellite belonging to a constellation will be equipped with laser/optical transceivers for transferring data communication information between them as well as from/to the constellation of optical ground stations (OGSs). This chapter discusses the most recent free-space optical (FSO) communication technology advances to achieve all-optical high-capacity communication systems for seamless global communication system performance. This chapter presents the concepts of optical satellite space networks relevant to constellation design and covers the establishment of satellite-aided Internet. Some of the device technologies include laser beam steering technology with no moving parts and the MEMS-based fast steering mirror specifically useful for CubeSat constellations. Inter-satellite communication system is also addressed for future development of constellation of satellites. Finally, satellite-based global quantum communications and integrated space networks are also discussed. Challenges and progresses for implementing quantum key distribution (QKD) over long distances across free-space channels are also specifically addressed in this chapter. Recent developments of implementing QKD for LEO-to-ground link as well as for inter-satellite links (ISLs) in the presence of atmospheric turbulence are discussed and explained.
