The results show that leveraging Walker constellations as relays significantly improves SSO systems, effectively compensating for their coverage limitations.
Abstract
The availability of abundant solar energy is driving renewed interest in orbital computing infrastructures hosted on Sun-Synchronous Orbit (SSO) constellations. However, these constellations suffer from limited instantaneous Earth coverage and constrained direct-to-ground, which is clearly incompatible with the connectivity and responsiveness requirements of datacenter clients. In this paper, we propose a hybrid architecture where SSO satellites offload traffic through Low Earth Orbit (LEO) Walker constellations—such as OneWeb and Starlink—which act as a dynamic relay layer toward the ground. We design and evaluate dynamic inter-orbital link topologies enabling SSO-to-Walker connectivity and analyze their performance in terms of link availability, relay opportunities, path continuity, and network resilience. Our results show that leveraging Walker constellations as relays significantly improves SSO systems, effectively compensating for their coverage limitations.
Large low-earth orbit (LEO) satellite constellations are revolutionizing network access globally by delivering potential high-capacity, low-latency communication, fueling innovation and accelerating research in advanced space-based non-terrestrial network architectures. Consequently, a research testbed that allows flex...

To achieve ubiquitous global coverage, low Earth orbit (LEO) satellite Internet of Things (IoT) constellations increasingly rely on multi-layer orbital architectures. However, characterizing their performance under practical Rician channels faces a significant challenge due to inherent analytical intractability. In thi...

For distributed link-state deployments on stable inclined-shell topologies, these results show that area division is a principled, geometry-driven design choice; they do not claim that PBAR supersedes centralized or geographic routing.

Orbital data centres are no longer theoretical. The first nodes are already in low Earth orbit, and inter-satellite laser links are routing data through vacuum, where light travels 47 per cent faster than through fibre. This paper examines how that shift rewrites the rules of networking, AI infrastructure and global co...

To enable global connectivity through 6G, the efficient operation of hierarchical satellite networks that integrate geostationary (GEO) and low-earth orbit (LEO) satellites is paramount. A significant challenge in achieving this operational efficiency lies in the dynamic association between the extensive array of LEO s...
