Phase IFoundation

Background

Overview

Addresses the digital divide and rural connectivity challenges; strategic importance for communication infrastructure; raises concerns about space debris and orbital traffic management; impacts the global telecommunications industry and regulatory frameworks.

Satellite constellations for internet services involve deploying a large network of satellites, often in Low Earth Orbit (LEO), to provide global or regional broadband internet access. These systems aim to deliver high-speed, low-latency connectivity, especially to underserved and remote areas where terrestrial infrastructure is limited or non-existent.

Phase IIStatic core
