Time Appliances Project Call #168 (September 23, 2026)

Abstract: This presentation introduces the main features of the novel Profile for Aerospace (802.1DP) for time-sensitive networks (TSN), thereby outlining how the new profile can substantially reshape, optimize, and streamline next-generation networks for aerospace and defense systems. Thus, our approach delivers a converged, deterministic, and secure Ethernet backbone for future aircraft, launch vehicles, defense platforms, and space systems by combining optimized versions for aerospace and defense of the main components of TSN, which include traffic shaping, redundancy, synchronization, and network management, with the inherently robust and high-performance White Rabbit timing. This effectively paves the way for enhanced determinism, resilient time distribution, and high-performance synchronization and frequency transfer to drive our main use cases, which span next-generation avionics networks, robust positioning, navigation, and timing (PNT), deterministic free-space optical communications (FSOC), and even microlauncher systems. We support these with our core building blocks, TSN platforms, FPGA IP modules, real-time software, validation frameworks, and certification activities, to ultimately implement our vision of scalable, optimized, secure, and certifiable TSN backbone networks for the next generation of aerospace platforms. Speaker: Jorge Sánchez-Garrido holds a Ph.D. in Communication Technologies (2021) from the University of Granada (Spain). He is a Technical Lead at Safran Electronics and Defense Spain, where he specializes in FPGA architecture, time-sensitive networking (TSN), and White Rabbit (WR) timing. He has contributed to the avionics of the Miura-1, a pioneering application of TSN for aerospace, and to the design of high-performance TSN switches. In addition, his interests include network management platforms, the use of high-accuracy synchronization and deterministic networks to implement the control plane of quantum communications, quantum computing, and to support the machine-protection system of high-energy physics facilities.
