Abstract

This study is a part of a general constellation design project conducted in Skoltech Space Center. The main objective of our work is to outline and validate a procedure to derive preliminary requirements for a microsatellite in a constellation to provide global internet service. Thus, we consider an orbital motion of all satellites within a given constellation pattern (e.g. Walker delta, Walker star, some flower constellation line-ups, etc.), the service provided to potential global customers (accounting for the satellite coverage geometry, world population density models, and the internet traffic demand). The latter models are based on the 2020 NASA Socioeconomic Data and Applications Center gridded population count map. For more precise predictions, the following factors are taken into account for each point in the satellite field of view: time (accurate to one hour), population, country and internet penetration rate in that country respectively. Finally, given the estimated required single-satellite link-budget, we proceed to analyze an inter-satellite laser communication subsystem, which, in turn, drives the requirements to attitude control and electrical power satellite subsystems.
