Description
Functional avionics for a Satellite means architecture and technologies targeting definition, design, implementation and validation in Computers & SW intensive equipment of functions and algorithms which are coming from various system levels (complete system, sub-systems, platform, equipment, boards), from very different functional chains (Command & Control, Flight management, GNC, Image processing, payload and instruments data processing…), with a large variety of criticality and safety levels.
On avionics architecture and computing domain, initial requirements and design engineering of new products with computers, on-board software, system functions and applications algorithms (GNC, Autonomy, Mission planning, payload data processing), sensors and actuators, payloads are key for mastering cost, schedule, quality and risks of the avionics development.
The main objectives of this project are first to improve the early maturity of the On-Board Functional Avionic requirements and design, in particular through an improvement of the interfaces between Operations, FDIR and System to Software, to make available to the Avionics architects a set of methods and tools which are adapted to the different operational situations they are facing, to better address and manage the system complexity, like the dependencies inside the architectures and in between, and for the interface definitions and finally to provide and assess process(es), methodology (ies) and tooling to design a spacecraft avionics architecture using MBSE controlling and reducing the project risks and costs, including flexibility of the avionics architecture to cover different similar mission profiles. It will also propose recommendation for links to the others MBSE initiative for full spacecraft system, other sub-systems and ground systems.
The presentation will introduce main expectations out of a successful MBSE implementation in this domain, experience feedbacks of first use cases, main trends for the next step.
