摘要

The definition and reuse of generic softwarernarchitecture for launchers is not so usual for severalrnreasons: the number of European launcher families isrnvery small (Ariane 5 and Vega for these last decades);rnthe real time constraints (reactivity and determinismrnneeds) are very hard; low levels of versatility arernrequired (implying often an ad hoc development of thernlauncher mission). In comparison, satellites are oftenrnbuilt on a generic platform made up of reusablernhardware building blocks (processors, star-trackers,rngyroscopes, etc.) and reusable software building blocksrn(middleware, TM/TC, On Board Control Procedure,rnetc.).rnIf some of these reasons are still valid (e.g. the limitedrnnumber of development), the increase of the availablernCPU power makes today an approach based on arngeneric time triggered middleware (ensuring the fullrndeterminism of the system) and a centralised missionrnand vehicle management (offering more flexibility inrnthe design and facilitating the long term maintenance)rnachievable. This paper presents an example of genericrnsoftware architecture which could be envisaged forrnfuture launchers, based on the previously describedrnprinciples and supported by model driven engineeringrnand automatic code generation.
