| Summary: | In space exploration, CubeSats—small satellites of less than 10 centimeters—challenge conventional knowledge. Tightly packed into little more than the size of a shoebox, but with boundless potential nonetheless, these technical marvels are directing a revolution in the fight for space. Their revolutionary influence stems not only from their diminutive size but also from their extraordinary contribution to democratising utilisation of space, breaking through traditional barriers to understanding. The primary goal of this project is to improve a single aspect of a CubeSat prototype. Specifically, it is desired to push the boundaries of new methods in the field of Attitude Determination and Control Systems (ADCS). After a thorough evaluation of the prototype’s present state, special attention has been paid to resolving any identified performance flaws. The result of these efforts was the creation of new operating modes that are purposefully used to maximise the performance of the current control systems. Simultaneously, little problems like inflexible drive configurations, code optimisation, and the Inertial Measurement Unit’s (IMU) limited resolution were carefully fixed. These efforts produced groundbreaking outcomes that closed the door on enduring problems from earlier studies, like static errors in position control, and opened up new research directions. A number of significant findings support these improvements’ accuracy and efficacy. Moreover, the Simulink model that came before this project experienced a significant transformation. By achieving better block diagram arrangement and better parametrization, the model’s quality and readability have been greatly increased. Remarkably, the improved model showed almost indiscernible discrepancies between its output and actual experimental data, confirming the new model’s careful parameterization. This significant advancement highlights the project’s dedication to accuracy and creativity in the ever-evolving field of CubeSat technology, while also reaffirming its technical strength |
