Introduction
The cost of producing and launching satellites in space has dropped significantly over the last 10 years [1]. This has led to the (planned) deployment of several constellations of satellites for communications, like Starlink, OneWeb and Amazon's Kuiper system [2]. These systems were initially targeting the fixed wireless market, but now the focus is moving to the smartphone and loT device market [3], delivering connectivity to handhelds through satellites. This solves the issue of coverage holes in areas without terrestrial coverage by providing truly global coverage.
