RUAG Space and TTTech aim to provide fast TTEthernet for NASA Lunar Gateway

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 US 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.

G20 expected to back OECD's digital tax proposal
Washington (AFP) Oct 18, 2019
G20 finance ministers Friday are expected to give the green light to an OECD proposal that aims to find an agreement on taxing global tech giants by June. The deal aims to solve the puzzle on how to tax technology firms, which shift the bulk of their earnings to low-tax jurisdictions, a major challenge with the increasing digitization of the economy, while heading off a myriad of new tax laws from individual governments. The Organization for Economic Cooperation and Development (OECD) will prese ... read more
