Space exploration enables improvements for life on Earth through technology developed and discovered thanks to new research opportunities. However, space flight also poses a unique range of challenges in developing and manufacturing spacecraft-equipment due to the harsh environment and the difficulty in maintaining systems in space. This is why safety, fault-tolerance and availability are key to ensure spacecraft mission success.
Other key factors, especially in international endeavors with large supplier ecosystems such as NASA’s Artemis, are modular and scalable solutions based on open standards that reduce system complexity and therefore save cost during development, production, and operation. Open international standards ensure interoperability and compatibility in space programs by creating a common set of design principles.
Developed as a cross-industry technology, Time-Triggered Ethernet has become an established standard in the space industry. Hence, a large number of research projects have been carried out. In 2007, NASA decided to deploy Time-Triggered Ethernet on the NASA Orion spacecraft as backbone network. This major reference project is highlighted in this section, as well as our contribution to NASA’s Gateway and the next generation European launcher Ariane 6. In all these projects, a Time-Triggered Ethernet network is used for data transmission.
Currently a lot of work is also being carried out in Europe to:
