Description
Spacecraft Platforms avionics and Payload systems currently rely on three main datalink standards for covering the on-board communication: 1553, Can Bus and SpaceWire. However, none of these technologies provide an efficient and reliable solution for future applications requiring more that 1Mbps of data transfer rate together with stronger real-time and quality of service requirements. For Ariane6, Orion and other future manned flight and in-orbit space vehicles, an Ethernet based solution with the Time-Triggered protocol (TTE) has been selected and is currently being developed. The current development of Time Sensitive Network (TSN) standard protocol on Ethernet is an opportunity for providing future on-board communication solutions fitting needs of future space applications while allowing synergy with other markets with the expectation of high performance and more affordable space avionics products based on COTS building blocks and standard.
This presentation will provide the rationale for Airbus and other space industrial partners to evaluate and prepare a roadmap on Ethernet TSN technology for being use on future space applications. An overview of in-going relevant preparatory studies and developments with agencies and other partners will be provided.
