ESA’s HydRON program aims to demonstrate a next-generation satellite communications network with terabit-per-second capacity, leveraging optical links between satellites and diverse ground terminals.La Plata Today
The European Space Agency (ESA) has contracted the third tranche of its HydRON program, which aims to develop high-speed optical communications links between satellites and ground terminals. The $42.4 million Element 1 contract will involve a diverse mix of optical terminal providers as the program works towards demonstrating a terabit-per-second-capacity network across multiple satellite orbits.
Why it matters
The HydRON project represents a major step forward in the development of ultra-high-speed satellite communications, which will be crucial for meeting the growing global demand for data-intensive applications like 5G, internet of things, and real-time video streaming. By leveraging optical communications, the system can achieve far greater bandwidth than traditional radio frequency links.
The details
The HydRON program is designed to provide in-orbit demonstration of a terabit-per-second-capacity network, including satellites in multiple orbits communicating with diverse user terminals. The $42.4 million Element 1 contract will involve multiple optical terminal providers, with Canadian company Kepler Communications serving as the system prime contractor.
The ESA contracted the third tranche of the HydRON program on April 14, 2026.
