ON-BOARD PROCESSOR AND NETWORK MATURATION FOR ARIANE 6

摘要

In the past three years, innovative avionic technologiesrnfor Ariane 6 were evaluated in the tail of three mainrnprograms involving various stakeholders: FLPP (FuturernLauncher Preparatory Program, from ESA), AXErn(Avionic-X European, formerly Avionique-X, Frenchrnpublic R&T program) and CNES R&T program relyingrnon industrial partnerships.rnIn each avionics’ domain, several technologies wererncompared, analyzed and tested regarding spacernlaunchers system expectations and constraints.rnWithin the frame of on-board data handling, tworntechnologies have been identified as promising: ARMrnbased microprocessors for the computing units andrnTTEthernet for the on-board network.rnThis paper presents the main outcomes of the datarnhandling preparatory activities performed on the AXErnplatform in Airbus Defence and Space – Les Mureaux.
