ReOrbit, a Helsinki-based leading provider of software-enabled satellites, joins the European Space Agency (ESA) high throughput optical network (HydRON) programme as a space segment partner.  

The two existing consortia, led by Airbus Defence and Space (ADS) and Thales Alenia Space, JV between Thales (67%) and Leonardo (33%), have both contracted ReOrbit for satellite architectural support during the ongoing phase A/B1 studies for the end-to-end demonstrator of the HydRON vision. ReOrbit brings unique expertise and heritage of space data relay technologies and systems, specifically satellite architectures, optical payload management and data processing. For the HydRON programme, ReOrbit will provide assessments of various satellite solutions for different orbits and payload configurations.

The HydRON vision aims to demonstrate “fibre-in-the-sky” technologies and is a European response to the demand for fast and high-volume data transport where laser-based satellite communication has the potential to cost-effectively complement terrestrial infrastructure for a range of services. HydRON encompasses the maturation of optical communication technologies and the provision of high-capacity data transport and flexible network services by connecting space and ground assets via an optical network. HydRON's key objective is to create a system that allows a seamless inter-operability between elements of the optical space network and terrestrial systems.

The phase A/B1 conclusions shall serve as a basis for the subsequent implementation phase B2/C/D/E1 with first satellite launch in 2026. The HydRON programme is part of ESA’s ARTES 4.0 Strategic Programme Line on Optical and Quantum Communications within the ScyLight Programme.
