Spacecraft Architecture

• 20 h CNES
• Educational content:
  • To understand how the requirements and the constraints of a mission orient the design of a spacecraft.
  • To design a satellite and its ground segment it is first necessary to express the mission needsand to challenge them against the requirements and the making constraints
• Description: The system approach will be done in continuity with UE21.5, the following points will be treated
  • customer needs analysis within the programmatic context
  • mission analysis and operational plan
  • payload requirements
  • Satellite functional chains and equipment description
  • citical subsystems identification
  • ground / board management
  • system analysis and main trade-offs
  • architectural principles
  • the main system budgets
  • preliminary and detailed design
• Details on the lecture:
  • Day 1: early steps of a mission concept and space mechanics (4 hours)
    • The mission design
    • orbital mechanics
  • Day 2: System and satellites engineering (4 hours)
    • System engineering
    • functional chains of a satellite
  • Day 3: From mission requirements to the satellite design (4 hours)
    • From customer needs to satellite
    • The case of an Earth observation mission
    • The case of an Astrophysic mission
  • Day 4: "Visit to a NEO" sizing of the mission (4 hours, working groups)
  • Day 5: "A telecommunication system sizing" (4 hours, working groups)
