The diploma thesis explores the potential use of low-cost picosatellites for educational purposes. The thesis includes design, implementation, and testing phases, culminating in a high-altitude balloon launch. The introduction provides a general overview of picosatellites but lacks specificity and a strong connection to the high-altitude balloon experiment described later. The design is well-documented; however, it lacks the required complexity. Ready-made modules were used instead of specific components, which further simplified the design. It is actually surprising that this technically poor design produced such good results. The firmware development process is explained, but significant issues with the GPS and barometer modules, which were non-operational, indicate inadequate debugging and validation. The high-altitude balloon launch was a notable achievement, but the data collected were incomplete, and the TTN logs were not reconstructed. Functional testing for key components was insufficient. Many project aspects were completed last minute, reflected in incomplete testing and unresolved issues. This rushed execution detracts from the technical performance of the satellite. The language level and readability of the work is good, however, there are multiple typographic errors in the work. Despite shortcomings, the project demonstrates innovation and a successful retrieval of the test electronics post-launch, showcasing practical problem-solving skills. In conclusion, the thesis presents a solid foundational effort with notable design and partial implementation achievements. However, it falls short in operational validation of key components and completeness of data collected. The rushed execution and incomplete testing significantly impact the overall quality of the work.
