Network platform delivers real-time communication for NASA
TTEthernet network platform was baselined by NASA and other space agencies for deep space missions and the related Artemis program.

TTTech Aerospace together with RUAG Space, a strong design and manufacturing partner, will provide the TTEthernet network platform for the Power and Propulsion Element (PPE) for NASA’s Gateway being designed and built by Maxar Technologies. PPE will be the main power source of Gateway, the orbiting cislunar outpost built by NASA and its many partners and will provide power, maneuvering, attitude control and communications.

Gateway the foundation of NASA’s Artemis program, which aims to land the first woman and next man on the Moon by 2024 and eventually enable future crewed missions to Mars. TTTech Aerospace and RUAG Space will deliver the first equipment to Maxar in mid-2021.

“Maxar completed  the Systems Requirements Review for PPE, and we are now beginning to contract our sub-suppliers. We chose TTTech Aerospace because they can provide us with a complete, fault-tolerant, mature network solution allowing Maxar to implement our mission-critical applications. TTEthernet technology forms the backbone for inter-element data and network communications across the combined PPE-HALO spacecraft,” says Vince Bilardo, Senior Executive Director for NASA Programs at Maxar Technologies.

“TTTech Aerospace and RUAG Space, its partner for space products design and manufacturing, have proven experience in designing and delivering mission-critical systems and TTEthernet networks for space. TTTech Aerospace has a dedicated team of software and systems engineering experts at TTTech North America, in our Houston, Texas office. They are working closely with Maxar to find the best solution based on commercial off-the-shelf TTEthernet products for the exacting requirements of this demanding space project,” explains Bob Richards, Vice President Space, TTTech North America.

The PPE will be integrated on the ground with Northrop Grumman’s Habitation and Logistics Outpost (HALO) element of Gateway, and the combined PPE-HALO spacecraft will launch aboard a commercial heavy-lift rocket.
