About

C3S offers a range of scalable CubeSat platforms from 3U to 16U, specifically developed for constellation purposes with a focus on Earth Observation and IoT. These platforms provide tailored space and technology to accommodate payloads of various sizes, supporting diverse applications such as crop growth monitoring, disaster damage mitigation, and in-orbit demonstration (IOD) demands. A key strength across all platform sizes is the meticulous attention paid to thermal design during development. The structures are optimized for high dissipation density and thermo-elasticity, benefiting both the payload and the platform. The unique radiator design allows for unparalleled freedom in payload dissipation and offers unprecedentedly high payload power availability. The 6U, 12U, and 16U buses also provide great flexibility regarding the shape and positioning of the payload.
