Cube sat A Modular Cube sat For Low-Earth Orbit Experiments

This paper presents the design and development of a modular Cube Sat platform for educational and research applications in low-Earth orbit. The proposed 1U Cube Sat (10cm × 10cm × 10cm) incorporates innovative design features enhancing modularity, power efficiency, and payload adaptability while maintaining standard deployment compatibility. Our methodology encompasses comprehensive structural design, subsystem integration, and prototype development validated through finite element analysis, thermal simulations, and functional testing. Results demonstrate successful integration of command and data handling (C&DH), power distribution, and payload interface systems with a final prototype mass of 1.12 kg, leaving sufficient margin for educational payloads. The platform supports various applications including Earth observation, atmospheric measurements, and technology demonstrations, making space- based experimentation accessible to educational institutions. This research contributes to democratizing space access for academic purposes while addressing key challenges in small satellite development
