A simulation framework for analysing and optimizing routing strategies in multi-orbit LEO, MEO and GEO satellite constellations

This article presents an advanced simulation framework for analyzing complex multi-orbital satellite communication networks. The system is designed to address the challenges inherent in modern multi-orbit LEO, MEO and GEO satellite constellation management, with particular emphasis on dynamic routing optimization and network topology analysis. The architecture supports detailed investigation of network behavior across diverse orbital configurations, from basic LEO satelites deployments to sophisticated hybrid LEO/MEO/GEO networks. Key features include temporal synchronization protocols, real-time topology visualization, and robust data acquisition capabilities for performance metric analysis. The framework demonstrates particular efficacy in evaluating routing strategies within dynamic network environments, supporting both accelerated and real-time simulation visualization modes. Through a series of progressive validation scenarios, we demonstrate the system's capability to analyze network resilience, optimize communication paths, and evaluate routing protocols under varying operational conditions. The results indicate successful management of complex network topologies, efficient handling of dynamic connectivity patterns, and effective cross-orbital communication integration.
