Kepler Leads ESA's Future Optical Network

Kepler Communications has been selected by the European Space Agency (ESA) to lead a hosted payload mission for the HydRON program. This initiative focuses on testing terminal interoperability for ESA's flagship optical relay network.

Kepler secured an 18.6 million euro contract to lead this mission, which is the final element in demonstrating HydRON's multi-orbit, terabit-per-second transport system. This network is designed to extend terrestrial fiber networks into space.

The mission, slated for deployment around 2028 in low Earth orbit (LEO), will validate interoperability across multiple optical communication systems. Kepler will supply a satellite bus for the mission, collaborating with European partners, including Germany's Vyoma, which will contribute a space situational awareness payload.

HydRON is envisioned as the world's first multi-orbital optical communications network, offering resilient and efficient data transfer. Kepler is also developing its own optical data relay constellation, having launched the first tranche of 10 satellites in January. HydRON's Element 1 satellites are expected to be integrated into Kepler's Tranche 2 deployment, scheduled for approximately 2028.
