AAUSAT 2D attitude test bench

Attitude control (pointing of the satellite) is very critical:

2D test bench

• radio communication
• experiments

Proposal short

Design, develop and implement a attitude control testbench

• mechanics
  • double set Helmholz coils (See picture below)
  • non magnetic cubesat
• electronics
  • control of Helmholz coils
  • onboard computer
  • magnetic field sensors
  • suntracker
• communication
  • radio link (based on AAUSAT3 CSP spacelink ?
  • onboard computer
  • fail resilient system design
• control - running on external node (PC)
  • time varying and rotating Helholz mag field
  • dynamic modelling of the rotating cubesat
  • design of attitude control

The goal is quite clear - to have a working setup with control, where it is possible to extend or exchange the control algorithms.

HW

• two yagii rotors available
• one 1.8 m dish
• arduino, pc, linux,freertos, csp,...
