Like all complex spacecraft, planetary entry probes require reliable, performant and resource-efficient avionics to successfully fulfil their mission. Due to specific mission constraints and targets, high integration as well as power and mass efficiency are particularly important.
The Data Systems Division / Electrical Engineering Department of ESA’s Directorate for Technical and Quality Management  has been actively involved in development of avionics architectures, networks, interfaces, and hardware as well as software and IP core components for a variety of mission types and applications. An important focus of the work was – and continues to be – standardization of interfaces, protocols and algorithms in order to facilitate re-use and compatibility of individual building blocks.
An overview of the ongoing developments on avionics architectures is presented. State of the art network and processing node types and their elements with strong relevance for planetary probe avionics are introduced. New types of interfaces and components under development as well as related technologies are presented. The ESA IP core service is introduced and explained, and the relevance of ongoing and planned developments in the avionics area for planetary entry probes and their systems and payloads is discussed.
