INTERNET PROTOCOL ROUTING IN CIS-LUNAR SPACE
Over the last five years, integrating space systems into the global Internet paradigm has advanced significantly. Space constellations and networks are now commonplace; however, current implementations remain limited to networks managed as single terrestrially orchestrated systems or orchestrated hybrid mixtures of interacting space networks. This centralized orchestration approach constrains autonomous operations, requires continuous ground station…

GEO–LEO Hybrid Networks Using Laser Communication Terminals: A Scalable Architecture for High-Throughput and Sovereign Space Connectivity
The growing demand for high throughput, resilient and sovereign space communication is accelerating the convergence of LEO and GEO systems into hybrid network architectures. LEO satellites provides low latency and flexible regional coverage, while GEO platform offer continuous visibility, centralized routing and stable long term operations. Combining these complementary capabilities enables a unified communication backbone…

Quantum Key Distribution for Secure LEO Satellite Constellations: A Scalable Protocol and Deployment Model
As global reliance on satellite communication networks intensifies, securing data links in Low Earth Orbit (LEO) becomes critical. Quantum Key Distribution (QKD), particularly the BB84 protocol, offers provably secure encryption through the transmission of quantum states. However, practical deployment at constellation scale poses challenges, including limited pass durations over ground stations, atmospheric attenuation, and the…

MediSat: A Secure Delay-Tolerant CubeSat Constellation for Medical Data Relay in Infrastructure-Degraded Environments
Reliable transmission of medical data during disasters and in remote regions remains a critical challenge due to damaged, congested, or nonexistent terrestrial communication infrastructure. This paper presents MediSat, a SmallSat-based system concept for secure, delay-tolerant relay of medical data using a constellation of CubeSats operating in low Earth orbit. The proposed architecture employs a store-and-forward…

Scaling Optical Inter-Satellite Networks for Resilient Smallsat Constella
As smallsat constellations transition from experimental deployments to operational infrastructure, network scalability, resilience, and secure data transport have become primary system-level constraints. RF-based crosslinks increasingly face spectrum congestion, limited throughput, and architectural complexity when applied at constellation scale. Optical inter-satellite links (OISLs) offer a compelling alternative, but successful deployment requires careful integration across spacecraft design,…
