C3S Elektronikai Fejlesztő Kft.
C3S LLC is a Hungarian space industry company specializing in designing and manufacturing high-reliability 3-16U platforms and robust and redundant subsystems that meet the requirements of scientific and industrial IoT constellations, or Earth observation missions. The company’s Mission Operation Centre tracks and manages the entire life cycle of missions, from launch to deorbiting. C3S has gained a prominent position among nanosatellite companies by implementing large satellite solutions and technologies in nano-size, which grants long life cycles and high reliability for spacecraft. In addition to CubeSats, the company also designs electrical power systems and payload control systems for large satellites.
Relevance to the space industry
C3S LLC develops and manufactures highly dependable 3/6/12/16U platforms and redundant, yet affordable subsystems like OBC, EPS, and communication modules to meet the requirements of IoT, Earth Observation and space monitoring constellation missions. Beyond the world of CubeSats, we participate in large satellite projects as the designer of power distribution systems and payload synchronization. Our devoted team will be at your service from mission planning throughout the operation of the entire mission, until deorbiting. To gain large satellite development heritage, C3S joined several project related to payload syncronization and power distribution, including PLATO 2.0 and SMILE.
