Abstract
In the present paper the work carried out in relation to the Attitude, Control and Determination
Subsystem (ACDS) of the UPMSat-2 is summarized. This engineering project is integrated within the
UPMSat-2 mission framework. This 50-kg satellite has been designed and manufactured by the
Polytechnic University of Madrid (Universidad Politécnica de Madrid).
The development of this ACDS comprises the selection of the different parts, sensors (magnetometers)
and actuators (magnetorquers), the design of the control law, the testing campaigns of the different
subsystem’s parts, and its verification. The magnetometers and magnetorquers were tested in the
IDR/UPM Institute facilities at Montegancedo campus, in order to check its accuracy. Besides, the
effect of their uncertainty levels on the satellite’s stabilization process once its normal attitude has
been perturbed, were studied.
The control law is based on B-dot, being thoroughly simulated by using Monte Carlo analysis. Finally,
the last testing campaign, carried out during the final integration stages of the satellite is also
summarized. The results obtained show a strong and reliable spacecraft control subsystem.
