The Role of AI in Managing Satellite Constellations
Modern satellite mega-constellations—groups of hundreds or thousands of small satellites working together—are transforming how we connect the world. Yet, managing these networks presents unique challenges: constantly moving nodes, limited onboard computing power, and a need to minimize communication delays. The ConstellAI project, supported by the European Space Agency, explores how artificial intelligence (AI) can optimize two critical tasks: Data Routing: Choosing the best path through the network to send data quickly and reliably. Resource Allocation: Distributing limited resources (bandwidth, power, time slots) among satellites and ground stations. Data Routing with Reinforcement Learning Traditional routing algorithms, like finding the shortest path on a map, don’t account for traffic jams (long queues) at network nodes. ConstellAI uses a technique called reinforcement learning (RL). In RL, a software agent learns from experience: it tries different routes, observes delays, and gradually discovers which paths minimize overall transit time. ...
