DE-CIX, a prominent Internet Exchange operator, has joined forces with the German Aerospace Center (DLR) to explore innovative methods of enhancing communication between low Earth orbit (LEO) satellite constellations and ground-based infrastructure. This partnership is part of the European Space Agency’s OFELIAS project, which focuses on leveraging laser-based communication systems to improve data transmission.
The primary objective of this initiative is to address the constraints of traditional satellite communication by developing cutting-edge protocols, algorithms, and procedures that can efficiently manage data flows between optical ground stations and satellites. While optical laser links offer higher bandwidth and data rates compared to radio frequency transmissions, they are susceptible to interference from atmospheric conditions such as cloud cover, fog, and rain. The OFELIAS project is slated to continue until mid-2026, with the aim of creating techniques that ensure more resilient and weatherproof optical satellite communication.
Hermann Bischl, Project and Group Manager at the DLR Institute of Communication and Navigation, emphasized the importance of developing innovative signal processing and network control approaches to enhance the availability of optical satellite networks for end users. He acknowledged the unique challenges posed by all-optical transmission but stressed that overcoming them is crucial for establishing reliable connectivity.
Matthias Wichtlhuber, Team Lead for Research & Development at DE-CIX, highlighted that the joint effort is geared towards making optical satellite systems robust enough to seamlessly integrate with terrestrial networks. With a wealth of experience in network interconnection spanning over three decades, DE-CIX views this research as an opportunity to shape the future of connectivity.
The collaboration between DE-CIX and the DLR also reflects broader ambitions for space-based digital infrastructure. As industries increasingly rely on advanced technologies such as artificial intelligence, immersive applications, and real-time robotics, the demand for ultra-low latency connectivity is on the rise. LEO satellites are positioned as a crucial enabler of such high-performance connectivity, offering global coverage and extending high-speed connectivity to underserved regions.
Ivo Ivanov, CEO of DE-CIX, emphasized that this endeavor aligns with the company’s overarching vision for Space-IX, an initiative aimed at directly interconnecting satellite operators with global content, cloud, and application networks. By enabling this level of interconnection, Ivanov believes that not only current applications will be supported, but also new business models spanning Earth and space will be established.
As space increasingly becomes a hub of economic activity, both DE-CIX and the DLR recognize the importance of integrating resilient satellite communication systems to build the next generation of digital infrastructure. Through the fusion of terrestrial interconnection expertise and aerospace research, this collaboration seeks to ensure that future networks can meet the escalating demand for speed, reliability, and global reach.
