Enseignant(s) :

Storni Bruno

Langue:

English

Summary

The course presents and analyses the different systems, architectures and components of spacecraft avionics (on board data handling and processing systems) controlling and commanding spacecraft and payloads (instruments). It will study typical bus structures (standard) used for S/C avionics.

Content

Introduction

Classification of spacecraft  functions depending of mission profile and identification of requirements and functions of on board data handling systems

Architecture

Typical spacecraft structure, system and major subsystem, redundancy management, data flow, telematics, service module, payloads

Space environment threads to electronics systems and mitigation tecnics

On board electronics susceptibilty to space radiation environment, radiation hardness, radiation mitigation techniques, HW and SW error detection and correction 

Components and subsystems

On board microprocessors and microcontrollers, on board communication buses and interfaces, mass memories, attitude and orbit control subsystems, payloads data processing, telemetry and telecommands 

Standards and system modelisation

Modelisation of flight avioncs systems, spacecarft onboard interface services SOIS, Standard Space links protocols,  standard data units, spacecraft synchronization time, buses and networks
