Thales Alenia Space (Tas), a joint-venture between Thales (67%) and Leonardo (33%), has signed a contract with the European Space Agency (ESA) for Element #2 of the HydRON (High-thRoughput Optical space Network) Demonstration System (DS) for the design, development, deployment and in-orbit demonstration of a full end-to-end optical system to verify and validate the world’s first all-optical, high-data-rate, multi-orbit transport network in space.

HydRON is set to transform the way data-collecting satellites communicate, using laser technology that will allow satellites to connect with each other and ground networks much faster.

By enabling rapid, high -capacity connections between satellites and ground networks, HydRON will significantly enhance our ability to collect and utilize data from space.

The project will be conducted with the support of the various space agencies involved in this challenge: 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).Other agencies are expected to join during the project to expand the mission’s objectives. HydRON form spart of ESA’s Optical and Quantum Communications – ScyLight programme within the Connectivity and Secure Communications directorate.

Thales Alenia Space’s role in HydRON-DS project

Tas, with its long track record in telecommunication networks and expertise in the production of optical terminals for space, developed in Zurich, has already coordinated a working group involving Telespazio, a joint venture between Leonardo (67%) and Thales (33%), responsible for the ground segment,and other Italian and European companies for Phase A/B1 of the HydRON-DS project. This work was completed at the end of the 2023.

Today, Thales Alenia Space in Italy is ready to lead a European industry consortium for building the HydRON-DS Element #2 mission partition, including the space segment (LEO collector satellite and GEO optical
payload) and ground segment (two optical ground stations, mission and network control center and satellite control center).

The project will develop and validate two concepts:

Fiber in the Sky: multi-orbit optical telecommunications at high data rates between space and ground assets.

Internet beyond the Clouds: innovative onboard routing techniques at high throughput (> 100 Gbps) to build an optical space transport network seamlessly integrated with terrestrial fiber-based networks.

The project includes up to two years of in-orbit demonstration to assess the capabilities of key technologies for optical communications and concepts of operations for the network architecture. It will also provide a service demonstration for potential demo users.
