NASA Awards LeWiz Phase III Contract for TTE-to-TSN Avionics Bridge

SAN JOSE – October 29, 2026 -- NASA has awarded LeWiz Communications, Inc. a Small Business Innovation Research (SBIR) Phase III contract to develop a TTE-to-TSN Bridge System that links spacecraft electronics running on two different Ethernet standards. The award builds on the company's collaboration with multiple NASA centers and the U.S. Navy.

LeWiz will connect Time-Triggered Ethernet with Time-Sensitive Networking

Conventional Ethernet does not fully meet the deterministic timing and reliability demands of aerospace systems. Time-Triggered Ethernet (TTE), advanced by SAE International and the Institute of Electrical and Electronics Engineers, has been deployed aboard NASA's Orion spacecraft in support of the Artemis program. Time-Sensitive Networking (TSN) extends Ethernet to time-critical communications, improved interoperability and advanced network management.
