- Thales Alenia Space embarks on the creation of the world’s first all-optical, multi-orbit optical space communication network.
- ESA’s HydRON project aims to enhance connectivity through cutting-edge optical communication tech.
- The initiative will bolster Europe’s technological independence in space connectivity solutions.
Cannes, February 14, 2025 – Thales Alenia Space, a joint venture between Thales (67%) and Leonardo (33%), has forged a pivotal contract with the European Space Agency (ESA) for Element #2 of the HydRON (High-thRoughput Optical space Network) Demonstration System (DS). This标志着 a significant advancement in the design, development, deployment, and demonstration of a full end-to-end optical system aimed at verifying and validating the world’s first all-optical, high-speed, multi-orbit transport network in space.
Transforming Space Connectivity
HydRON is poised to revolutionize the way data-collecting satellites communicate. Leveraging laser technology, HydRON will enable rapid, high-capacity connections between satellites and ground networks. This enhancement will significantly boost the efficiency of data collection and utilization from space, heralding a new era in space communication.
Strategic Partnerships
The HydRON project will be executed with support from multiple international space agencies, including the Italian Space Agency (ASI), the German Aerospace Center (DLR), the Polish Space Agency (POLSA), the Romanian Space Agency (ROSA), Enterprise Ireland (EI), and the Swiss Space Agency (SSO). As the project progresses, additional agencies are expected to join, further expanding its scope and goals. HydRON is a key component of ESA’s Optical and Quantum Communications – ScyLight programme within the Connectivity and Secure Communications directorate.
“I am thrilled that Thales Alenia Space will contribute to Europe’s technological independence in space connectivity,” said Giampiero Di Paolo, Deputy CEO and Senior Vice President, Observation, Exploration and Navigation at Thales Alenia Space. “We believe HydRON DS is vital for establishing a reliable and operational high-throughput optical network in space, paving the way for advanced commercial optical communications both in Europe and globally.”
“It’s an honor to partner with Thales Alenia Space on this groundbreaking project,” stated Laurent Jaffart, ESA’s Director of Connectivity and Secure Communications. “HydRON is set to maintain Europe and Canada as leaders in optical communication. With its interoperable design, this project will deepen ESA’s collaboration with international partners.”
Thales Alenia Space’s Role in HydRON-DS
With a rich history in telecommunications and extensive experience in optical terminal production, Thales Alenia Space has been instrumental in coordinating a working group led by Telespazio, a joint venture between Leonardo (67%) and Thales (33%), which managed the ground segment aspects of Phase A/B1. This ground-breaking effort concluded late in 2023.
Today, Thales Alenia Space is at the helm of a European industry consortium, overseeing the development of the HydRON-DS Element #2 mission segment. This includes the space segment (involving a LEO collector satellite and a GEO optical payload) and the ground segment (with two optical ground stations, a mission and network control center, and a satellite control center).
Key Concepts
The HydRON-DS project will validate two key concepts:
- Fiber in the Sky: Enabling multi-orbit optical telecommunications at high data rates between space and ground assets.
- Internet beyond the Clouds: Developing innovative onboard routing techniques to achieve high throughput (>100 Gbps) for an optical space transport network seamlessly integrated with terrestrial fiber-based networks.
The project will incorporate up to two years of in-orbit demonstration, evaluating key technologies for optical communications and operational concepts for the network architecture. It will also provide service demonstrations for potential users.
ESA’s Optical and Quantum Communications – ScyLight Programme
The European Space Agency’s Optical and Quantum Communications – ScyLight programme is dedicated to advancing optical and quantum technologies to revolutionize satellite communications. Part of the ARTES program, ScyLight supports research, development, and utilization of these advanced technologies. Key initiatives like HydRON aim to seamlessly integrate space assets into terrestrial communication networks. By advancing space-based quantum key distribution, ESA is paving the way for ultra-secure global connectivity.
