TTEthernet for NASA's Multi-Purpose Crew Vehicle
Avionics need to cope with increasing data rates and enable more modular architectures, at the same time launchers face strong market pressure through increased competition, affecting both development and recurring cost.
Further challenges are avoidance of both obsolescence and export restrictions at component level.
After several years of research funded by the French space agency (CNES) and afterwards by the European Space Agency (ESA), architectures based on TTEthernet are considered a great fit for launch vehicles. As a consequence TTTech offers a family of radiation tolerant TTEthernet controller ASICs in cost-efficient BGA housing.
These ASICs will be designed into all avionics equipment of Europe’s flagship launch vehicle, the Ariane 6.
