IRISH SPACE STARTUP, RÉALTRA, JOINS FORCES WITH AUSTRIAN TTTECH TO DEVELOP NEW TIME-TRIGGERED ETHERNET SYSTEM FOR FUTURE SPACE MISSIONS

Dublin based Réaltra and Austrian TTTech Aerospace are developing a new Time-Triggered Ethernet system in a project funded through the European Space Agency Future Launchers Preparatory Program (FLPP).

Dublin, 19 March, 2024 –

Irish owned Réaltra Space Systems Engineering and Austrian based TTTech Computertechnik AG have announced a collaboration to develop a Time-Triggered Ethernet system in a new project funded by the European Space Agency (ESA) under the Future Launchers Preparatory Program (FLPP).

By combining Réaltra’s expertise in aerospace solutions and TTTech’s know-how in real-time networking and safety, the project aims to develop a state-of-the-art TTEthernet® system, utilizing TTTech’s proven radiation tolerant TTE-Switch controller, for use on future launchers and space applications. This modular system will offer high-speed communication capabilities, precise synchronization, and fault tolerance for critical applications. The project aims to meet the requirements of the next generation of rocket launchers.

With the increasing demand for real-time communication in industries such as aerospace, automotive, and industrial automation, the need for efficient networking solutions has become crucial. TTEthernet technology enables cost savings thanks to modular, scalable system architectures. It reduces cabling as well as system complexity, integration, and testing efforts. Fault-tolerant, automated time synchronization, and fault containment are implemented in hardware, which increases safety and improves overall system availability.

“We are delighted to collaborate with TTTech to develop a platform product which masters regular Ethernet and Time-Triggered Ethernet that meets the needs of the next generation of launchers,” said Michael Martin, Engineering Manager of Réaltra. “This partnership brings together the strengths of both companies and will result in a highly reliable and efficient networking solution.”

Time-Triggered Ethernet is a scalable networking technology that uses time scheduling to deliver communication via Ethernet with up to 1 Gbit/s. Implementation of TTEthernet in a spacecraft allows it to transmit safety critical and regular traffic on a single physical network layer, which results in cost and complexity savings. Under this ESA funded FLPP project, Réaltra Space Systems Engineering and TTTech will collaborate to bring their hardware and software expertise together to develop an affordable, ruggedized, highly-reliable Ethernet switch for launchers which will be a highly attractive offering for both the newcomers and the established launch vehicle integrators.

Quote from Enterprise Ireland

Padraig Doolan, Irish National Delegate to ESA, of Enterprise Ireland, the State agency which supports Irish companies engaging in space technology developments with ESA, added: “Enterprise Ireland has a key role in the growth of an agile space-active enterprise sector in Ireland and provides a range of supports to space-active companies at various stages of development. We wish to congratulate Réaltra on this collaboration with TTTech on their recently funded ESA project.”

Quote from TTTech Aerospace

Werner Köstler, Member of the Executive Board – Aerospace at TTTech, comments: “We are excited to work with Réaltra on their compact TTEthernet platform which is suited for both launch vehicles and small satellites. TTTech Aerospace has pioneered the use of TTEthernet in space applications and welcomes this further widening of the European eco-system for TTEthernet-based avionics. So far, we have been working with partners of various sizes in France, Austria, Italy, Sweden, Spain, and Belgium.”

Quotes from Réaltra Space Systems Engineering

“We are delighted to partner with TTTech in this ESA FLPP funded project and look forward to progressing this technology for use in future launchers and spacecraft. As the global space economy continues to grow, we recognise the importance of developing and progressing new technologies to meet current and future demands.” said Danny Gleeson, CCO of Réaltra.
