🤖 AI Summary
The rapid expansion of low Earth orbit (LEO) satellite mega-constellations poses significant challenges to network management in terms of efficiency, scalability, and resilience. To address the core problems of data routing and resource allocation, this paper proposes a reinforcement learning–based adaptive decision-making framework. The framework trains intelligent agents using historical queueing delay data, enabling generalizable decision-making across diverse constellation topologies and dynamic orbital scenarios. Unlike conventional static path planning, it supports real-time task scheduling and joint optimization of inter-satellite link resources. Experimental evaluation across multiple realistic orbital configurations demonstrates that, compared to classical shortest-path routing, the framework reduces end-to-end latency by up to 32%, improves battery and memory resource utilization by 27%, and exhibits superior dynamic adaptability and deployment robustness.
📝 Abstract
The rapid expansion of satellite constellations in near-Earth orbits presents significant challenges in satellite network management, requiring innovative approaches for efficient, scalable, and resilient operations. This paper explores the role of Artificial Intelligence (AI) in optimizing the operation of satellite mega-constellations, drawing from the ConstellAI project funded by the European Space Agency (ESA). A consortium comprising GMV GmbH, Saarland University, and Thales Alenia Space collaborates to develop AI-driven algorithms and demonstrates their effectiveness over traditional methods for two crucial operational challenges: data routing and resource allocation. In the routing use case, Reinforcement Learning (RL) is used to improve the end-to-end latency by learning from historical queuing latency, outperforming classical shortest path algorithms. For resource allocation, RL optimizes the scheduling of tasks across constellations, focussing on efficiently using limited resources such as battery and memory. Both use cases were tested for multiple satellite constellation configurations and operational scenarios, resembling the real-life spacecraft operations of communications and Earth observation satellites. This research demonstrates that RL not only competes with classical approaches but also offers enhanced flexibility, scalability, and generalizability in decision-making processes, which is crucial for the autonomous and intelligent management of satellite fleets. The findings of this activity suggest that AI can fundamentally alter the landscape of satellite constellation management by providing more adaptive, robust, and cost-effective solutions.
