SAE AS6802 Using Ethernet for Embedded Systems in Aerospace, Defense, Ground Vehicle Applications
November 4, 2009 // Published as a news service by IHS
Ethernet would become the network protocol for electronics architectures for space, aerospace, defense, ground vehicle and other applications with a new standard developed by SAE International's AS-2 Embedded Computing Systems Committee.
The first production program using components compliant with the standard, SAE AS6802 - Time Triggered Ethernet (TTEthernet), will be NASA's Orion crew exploration vehicle, according to SAE.
Ethernet is standardized as Institute of Electrical and Electronics Engineers (IEEE) 802.3.
Targeted for time-, mission- and safety-critical systems, SAE AS6802 describes a set of services to meet the requirements of reliable, real-time data delivery in advanced integrated systems.
With TTEthernet, critical control systems, audio/video and standard LAN applications can safely coexist in one Ethernet network.
Initial supporters of SAE AS6802 standardization project are Lockheed Martin, Bombardier, Embraer, General Dynamics, Sikorsky Aircraft, Honeywell, BAE Systems, Ultra Electronics, GE Fanuc Intelligent Platforms, TTA-Group and TTTech. Lockheed Martin also works on several advanced integrated system programs using this technology.
SAE International’s AS-2 Embedded Computing Systems Committee addresses all facets of embedded computing systems – design, maintenance and in-service experience.
The committee is part of SAE's Avionic Systems Division.
