Definition ∞ LEO constellations are groups of artificial satellites operating in Low Earth Orbit, designed to provide global coverage for various communication or sensing services. These networks consist of numerous smaller satellites positioned relatively close to Earth, allowing for lower latency and higher bandwidth compared to geostationary satellites. They function collectively to ensure continuous service availability over wide geographical areas, with individual satellites handing off connections as they move across the sky. Their deployment aims to deliver internet access, navigation, and other data services, often reaching underserved regions.
Context ∞ LEO constellations are frequently featured in news regarding global internet access initiatives and advancements in satellite communication technology. Their potential to support decentralized networks and facilitate blockchain data transmission in remote areas is a growing area of interest. The discussion often addresses the economic viability, regulatory challenges, and environmental concerns associated with launching and maintaining these extensive satellite arrays. Future developments include denser constellations offering even greater data throughput and reduced latency.
