Descripció del contingut i pla d'activitats:
PhotSat is a 16U Cubesat devoted to astronomical photometry in the
design phase at the Institute of Space Studies of Catalonia and the
Universitat Politècnica de Catalunya. Due to its demanding pointing
requirements the ADCS is one of the critical subsystems.

In this Master Thesis, we explore different attitude control
alternatives for fine attitude corrections and benchmark them. The
possible actuators to be studied include but are not limited to,
variable-reflectivity surfaces to leverage solar radiation pressure,
moving masses and aerodynamic surfaces. In all cases, the control
mechanisms studied will provide small corrections to the main
actuators (reaction wheels).
 
Overview (resum en anglès):
The objective of this thesis is to propose and evaluate attitude determination methods and attitude control algorithms that take advantage of all onboard sensors and actuators. To achieve this goal, a MATLAB Simulink-based simulation environment was developed. Its primary purpose is to provide a platform for testing and tuning control algorithms.

The simulation enables the implementation and evaluation of the attitude determination and control algorithms. The work focuses on preparing the simulation environment, proposing an attitude determination algorithm, and comparing several attitude control strategies.
