Project based learning

  • 2nd semester, last year.
  • CDIO (Conceive-Design-Implement-Operate) syllabus.
  • Preliminary design of a realistic satellite mission.
  • Groups of 6 students where each of them get a role (manager, system, subsystem,

payload).

  • Documents:

– Requirements – Mission analysis – Final report

  • Final oral presentation.
  • Objectives:

– Subsystems interaction – System point of view – Technical reports – Oral presentations – Time management – Transversal skills

  • Completed with educational satellite for AIT.

In-house developments

  • Structure

– Low mass (<150 g) – Maximum useful volume – Modular configuration, highly configurable – Fully qualified

  • EPS

– High efficiency – Advanced MPPT – Highly configurable – Different power supplies

  • Solar panels
  • Antenna deployment mechanisms

– Minimum impact on CubeSat configuration – Can be located anywhere in the CubeSat

  • COM

– Full duplex – Downlink: UHF, 9600 bps, turnstile 4 monopole antenna – Uplink: VHF, 1200 bps, one monopole

  • Thermal Subsystem, Phase Change Material
