| Sumario: | This paper describes the study and design of a 1 DoF attitude control system for a 1U CubeSat based on reaction wheel with the aim of implementing it on a PCB along with a magnetorquers system. This thesis takes place in the frame of the PLATHON project which aims to develop a simulation platform for optical communications between nanosatellites by regrouping many students and teacher from the Polytechnical University of Catalonia (UPC). To do this, a complete state of the art presents the features of nanosatellites and the existing technology to control the attitude of a CubeSat. Then, the method used for reading and controlling the attitude of a CubeSat is explained. To be more precise, the principle of operation of two Inertial Measurement Unit (IMU) is shown to understand how the attitude can be red. Along with this, the controlling program of the reaction wheel system is detailed to have an overview of the different functions required to impose a certain positioning to the CubeSat. The design of the hardware components of the project is then presented. Most of the pieces have been drawn under Solidworks software and manufactured by a 3D printer. Finally, the result of some experiments made at the university laboratory with an air bearing system are presented. Those results are discussed and highlight the different problems encountered over the project. |
