AeroTSN-EP — Aerospace TSN Endpoint

Overview

AeroTSN-EP is a TSN (Time-Sensitive Networking) endpoint IP core for aerospace, defence and space, being developed jointly by SoC-e (Spain) and SafeCore Devices. SoC-e announced the start of development on 26 June 2026.

On-board systems are moving from federated, proprietary communication architectures towards integrated, software-defined and modular designs. Carrying mixed traffic over a common Ethernet network underpins that shift, but ordinary best-effort Ethernet cannot meet the requirements of critical applications. What is needed is bounded latency, controlled jitter, high reliability, precise time synchronisation and predictable behaviour under defined conditions.

TSN extends standard Ethernet with deterministic communication, traffic scheduling, redundancy and time synchronisation. For airborne networks this work is being consolidated into the IEEE 802.1DP IEEE 802.1DP profile, and AeroTSN-EP is designed around that standard.

It acts as a TSN-capable endpoint on FPGA-based platforms, letting deterministic Ethernet interfaces be implemented close to the application logic. The aim is to simplify development of systems where traffic generation, timing behaviour and redundancy mechanisms must be tightly controlled and verified.

Evaluation units, supported devices, Linux BSP, reference designs and volume-supply terms are not yet confirmed; we will check with the manufacturer at the time of your enquiry and reply. Positive ONE Group is happy to assist with device selection.

Developed with DO-254 in mind

Aerospace and defence systems demand rigorous assurance processes for hardware components. AeroTSN-EP is being developed against DO-254, the standard used for design assurance of airborne electronic hardware, with the aim of being certifiable up to DAL-A, the highest level in DO-254 is the development goal.

This targets use cases where the communication endpoint forms part of a safety-critical function and where traceability, verification, robustness and a controlled design process are essential.

Conformance to DO-254 DAL-A is published as a development goal and does not mean certification has been completed or obtained. If you need the current status, we will confirm it with the manufacturer.

Key specifications

The above is based on the specification published by SoC-e. Resource usage (LUT, FF, BRAM), supported devices, availability of an evaluation version, pricing and lead times have not been published. Tell us your requirements and we will enquire with the manufacturer.

Typical applications

• Airborne networks (a deterministic Ethernet backbone designed for IEEE 802.1DP)
• Communication endpoints carrying safety-critical functions such as flight control
• Integrated mission networks in defence systems
• On-board spacecraft communication where determinism and redundancy are required
• On-board communication architectures moving from proprietary schemes to Ethernet
