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
Cases studies
examples of flight avionics on International Space Station ISS, Automated Transfer Vehicle ATV, ExoMars (Rover, Lander and Orbiter)
Avionics on CAN
Exercices
Implement simple avioncs system components on an advanced design simulation and verification tool
