RUAG Space and TTTech partner to provide electronics for fast, reliable data transfer based on TTEthernet for NASA Lunar Gateway
24.10.2019
Space supplier RUAG Space and high-tech company TTTech are offering high-performance data exchange electronics for Lunar Gateway modules – in time for the ARTEMIS Mission challenge in 2024.
RUAG Space, a leading space supplier, and TTTech, a leader in high-tech network technology, are teaming up to provide space electronics for the NASA space station “Lunar Gateway”. In 2011, via a Space Act Agreement, TTTech and NASA standardized TTEthernet technology as an open industry standard i.e. SAE AS6802 together with several industry partners.
This open standard has recently been ratified by NASA, ESA, CSA and JAXA as the “International Avionics System Interoperability Standards” (or IASIS) for deep space applications.
TTEthernet technology allows fast and reliable data transfer on the “Lunar Gateway” space station, which will orbit around the Moon and serve as the portal to the surfaces of Moon and Mars.
RUAG Space will provide space qualified hardware that enables the use of this highly reliable technology in space applications. Both companies will offer these electronic products to all interested customers. TTEthernet is also used very successfully by the NASA Orion spacecraft and by the new European launcher Ariane 6 as the on-board avionics backbone network.
“Reliable products that are ready-to-use”
“This is a perfect partnership. An electronic product that brings together the strong experience from RUAG in space hardware engineering and manufacturing with the expertise in software and ASICs from TTTech”, says Peter Guggenbach, CEO RUAG Space. “We have invested a lot of resources into engineering and customers can trust us to bring a reliable product that is ready-to-use.
With our legacy of success, we will help customers save time and meet their ambitious mission schedules,” says Peter Guggenbach. The first crewed mission, i.e. ARTEMIS to the “Lunar Gateway” station, and the moon is planned for 2024.
“Unique safety-critical technology unmatched in the industry”
Christian Fidi, VP Products, Sales and Marketing of TTTech’s Aerospace business unit, highlights the safety and reliability of the technological solutions: “We have delivered a safety-critical standard that is proven and as yet unmatched in the industry.
Customers benefit from off-the-shelf hardware solutions that perfectly serve a highly competitive and dynamic space market. Time-Triggered Ethernet is faster and more reliable than any other technology in the market.”
Time-Triggered Technology
Time-Triggered Technology was invented by TTTech. The essence of this technology is to create networks that are fully deterministic, meaning each sender and receiver in a network knows when to send or expect a message. This brings several advantages: Not only are all failures that result in some latency in the network eliminated, it also allows to use the entire bandwidth of the links within the networks.
These advantages make the technology superior in terms of safety and reliability. Moreover, the implementation of the TTEthernet protocol is compatible with ordinary Ethernet traffic. Based on IASIS, Deterministic Ethernet is becoming the de facto standard for avionics in the space industry.
This makes the testing of space electronics much easier. Once in orbit, Time-Triggered Ethernet ensures the reliable data transfer among the computers used on board spacecraft or station – all with unparalleled speed and safety.
Direct technical support for U.S. customers
RUAG Space continues to expand its footprint in the U.S. as the office in Denver, Colorado, will increase its electronic competence and will serve as local interface and technical support to U.S. customers. “Our entire electronics portfolio – from onboard-computers, navigation receivers to antennas and more – can be ordered from Denver. With this expansion, we will continue to improve our service to our customers,” explains Peter Guggenbach.
