Performance Analysis of a Dual Terahertz/Ka Band Communication System for Satellite Mega-Constellations | IEEE Conference Publication | IEEE Xplore

The use of the electromagnetic spectrum in space has his-torically been motivated by scientific missions including Earth observations, space exploration, and relay satellites supporting such missions. Nonetheless, the recent commercialization of space has frenzied the push for higher data rates to serve newer applications enabled by space-based internet [1]. A space-based internet can greatly serve users living in remote areas where optical fiber networks are not cost-effective, and could provide lower latency in circumstances where terrestrial internet is prone to structural delays and sub-optimal interaction time between endpoints [2]. This has led multiple private companies to race towards establishing satellite mega-constellations to provide high-data-rate low-latency internet, such as with the SpaceX Starlink constellation [3]. Currently, the most suitable technologies for communication between the satellite constellations and the users (whether directly or through gateways) lay w
