Complex systems and small satellites
Robust structure, fine details
C3S LLC bridges the gap between nanosatellite and large satellite projects, offering 3–16U platforms and subsystems with exceptional reliability. Thanks to our flight heritage, our in-house developed redundant subsystems feature long lifecycles and high availability. Additionally, we design power distribution systems and payload synchronization for larger satellites. Building on this expertise our company stands at the forefront of SSA CubeSat development, specializing in space debris tracking and collision avoidance, offering a platform fully aligned with international space debris mitigation standards.

C3S SERVICES

Engineering services
C3S’s vast resources and the complex & interdisciplinary engineering know-how are all used for the benefit of high reliability components development along with quality-centered low volume manufacturing, both within the ground and the space segment. Our enthusiastic engineers have great experience in advanced electronics, integrated system designs, mechanical engineering or embedded software and are following strict ECSS standards.

Platform Development Kit
For a seamless integration process, we provide our payload partners with a Platform Development Kit. Interface documentation enables our clients to take full advantage of the devices and it also provides the required hardware to maintain a rea-time connection during the tests.

Mission Management
C3S provides turn-key solution when it comes to mission management. As an ESA prime contractor, we have vast experience in every milestone of a space project from mission preparation, through launch management until deorbiting. We guarantee mission success, all you have to do is share your goals and requirements with us.

Shared Payload Concept
Space made easily available with our shared payload concept, aligning with the most recent new space trends. Splitting up the payload bay of our platform between multiple players grants a cost-effective solution, along with giving a shorter-term access to space.

Find a GRASSHOPPER on the picture!
There is no milestone our GRASSHOPPER wouldn’t leap. We proudly post that together with ESA and Thales Alenia Space we closed the GRASSHOPPER’s Design Review, so now, before jumping to TRL5, we can concentrate on the climate chamber measurement and thermal simulation...

RadCube mission’s commissioning phase has come to an end and the satellite keeps on fulfilling its duties!
Since it has been set to LEO on 17 August 2021, RadCube operates well. On the platform developed by C3S LLC, every operation went according to the plans: solar wings have opened, the boom has been deployed, and at the end of the multistep commissioning phase, RadMag...

C3S participates on European Space Thermal Engineering Workshop 2021
Predicting the space environment is vital while designing a satellite, knowing hot or cold the components will get while in space in either direct sunlight or facing the dark space is a complicated task. Today our thermal engineers Zsolt Péterbencze and Tamás Henczi...
