KunturSat: Design and Development of a Picosatellite for the CanSat France 2024 Competition

ABSTRACT This paper presents the design, development, and validation of KunturSat, a picosatellite developed for the CanSat France 2024 competition. KunturSat integrates multiple technological innovations, including a flag deployment system, precise descent control via a 9-cell paraglider, and a biodegradable marking mechanism using purple corn extract (Zea mays var. amilácea (L.)). The structural design utilizes lightweight, high-strength materials, such as Ripstop nylon, and employs advanced 3D printing techniques, ensuring both durability and flight efficiency. A comprehensive series of tests was conducted to evaluate its performance, including vibration analysis, communication tests, support deployment trials, free-fall simulations, and drone-based launches. These assessments validated the mechanical, electronic, and telemetry subsystems under real-flight conditions. The results confirmed KunturSat’s effectiveness in executing its primary mission of biodegradable surface marking, alongside its secondary missions of vertical stabilization and flag deployment. Identified improvements include reinforcement of structural components to enhance resilience in adverse conditions. KunturSat contributes to the aerospace sector as an innovative and sustainable platform, serving as a foundation for future picosatellites with autonomous descent control and advanced deployment mechanisms. Additionally, it underscores the importance of STEM education (science, technology, engineering, and mathematics) and accessible aerospace technologies in fostering engineering expertise.
