C3S
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.
About C3S
C3S LLC is a determining player in the international nanosatellite industry. Our products and solutions serve and support both scientific payloads and industrial demands throughout the missions. Our mission planning activity encompasses 3-16U, high-reliability platform, and subsystem design, as well as the prelaunch simulation software and hardware development and mission operation environment development. Beyond the world of CubeSats, we participate in large satellite projects as the designer of power distribution systems and payload synchronization. Long lifecycle and high availability are the characteristics of our in-house developed, and redundant subsystems.
A 40-strong collective of young and creative space engineers and experts understanding all the related areas of engineering necessary for developing satellites stands beyond the technology-independent, world-level products. Innovation and added value are our guiding principles that manifest themselves throughout the entire lifecycles of the company’s products.
We develop our products with the partner’s scientific and business demands in our minds. We offer them tailored turnkey solutions that encompass the entire lifecycle of the mission, from planning through simulations, tests, and manufacturing to mission tracking and operation.
