Orbit-Routing Simulator: Advanced Routing in Multi-Orbit Satellite Networks

Traditional routing algorithms are not efficient when applied to multi-orbit satellite networks, encompassing LEO, MEO, and GEO satellites, as well as ground stations, since identifying optimal routing strategies jointly with a non-terrestrial network dynamic topology is a challenging topic. In response to that, this paper introduces the Orbit-Routing Simulator, a satellite simulation tool designed to tackle the intricacies of advanced routing algorithms. Orbit-Routing Simulator provides a robust environment for the design, testing, and evaluation of various routing strategies, tailored to meet the dynamic conditions of complex satellite constellations. It aims to enhance the efficiency and reliability of satellite communications by providing detailed insights into the operational effectiveness of the communication systems. This facilitates improved connectivity and network management by addressing the challenges of high mobility and variable communication channels in satellite networks. The paper concludes with several use cases and scenarios highlighting its practical applications and adaptability to real-world operational adjustments.
