Legal Aspects of Satellite Constellations [PDF]

open access: yesAir and Space Law, 2020
In recent years a few entrepreneurs proposed launching into space large fleets of satellites, consisting of hundreds of satellites, often referred to as ‘constellations’. Their role is to provide satellite services to the largest possible number of users on Earth.

Satellite Constellation Internet Affordability and Need [PDF]

open access: yesResearch Notes of the AAS, 2020
Abstract Large satellite constellations in low-Earth orbit seek to be the infrastructure for global broadband Internet and other telecommunication needs. We briefly review the impacts of satellite constellations on astronomy and show that the Internet service offered by these satellites will primarily target populations where it is ...

Self-organising satellite constellation in geostationary Earth orbit [PDF]

open access: yes, 2015
This paper presents a novel solution to the problem of autonomous task allocation for a self-organizing satellite constellation in Earth orbit. The method allows satellites to cluster themselves above targets on the Earth’s surface.

Extended Geometry and Probability Model for GNSS+ Constellation Performance Evaluation

open access: yesRemote Sensing, 2020
We proposed an extended geometry and probability model (EGAPM) to analyze the performance of various kinds of (Global Navigation Satellite System) GNSS+ constellation design scenarios in terms of satellite visibility and dilution of precision (DOP) et al.
