The aim of this thesis work is linked to a new R&D project owned by Tyvak International and is intended to demonstrate and implement a preliminary ROS2 based flight software framework applied it to a complex system like a nanosatellite. ROS2 is an open source set of libraries and tools for developing robotic applications and it is chosen since its usage is becoming very popular in mechatronics applications for its simplicity, modularity and it also provides built-in tools for simulation and debugging and a toolbox to easily integrate it with Matlab/Simulink. The first part of the thesis is dedicated to the hardware setup and the development of the software in ROS2.
