C3S LLC.

C3S LLC. The mission of C3S is to develop high reliability and high availability small satellite platforms by introducing new volume optimized technologies.

C3S was established in 2012 by the developers of the first Hungarian satellite, Masat-1. Since C3S has been engaged in and completed projects both terrestrial and space industrial. The mission of C3S LLC in the space industry is to develop high performance to size ratio subsystems for medium-sized satellite (< 500kg) by introducing new volume optimized technologies (such as payload power supply, p

ayload controller and ancillary electrical units); and to develop and provide high reliability and high availability small satellite platforms (< 50 kg) for industrial and scientific in-orbit-demonstration applications. The goal of C3S is to give to the customers the advantage in reliability, robustness, and integration by successfully utilizing the experience gained in space industry and space technology.

🚀 MAUVE featured on CORDIS

We are proud to see the results of the C3S-coordinated MAUVE project highlighted by CORDIS, the European Commission’s official research and innovation results platform, in a dedicated Results in Brief article.🌟

For C3S, MAUVE is an important example of how small satellite systems can support demanding space science missions — combining precise platform performance, reliable onboard systems, and a compact architecture capable of delivering valuable ultraviolet astronomy data from orbit. 🛰️✨

As platform prime, we are proud to contribute to a mission that continues to expand what small satellites can achieve in space science. 🌌

🚀 Indul a RAVEN műholdprojekt

Március 5-én sajtótájékoztatón jelentettük be a RAVEN CubeSat-projekt indulását, amely a jövő földi és űralapú kommunikációs rendszereinek fejlesztését szolgálja.

Az eseményen bemutattuk a projekt célját és jelentőségét, valamint a fejlesztésben részt vevő magyar ipari és akadémiai partnereket. A konzorcium vezetője a C3S Kft., partnereink között a Molaris Kft. és az Óbudai Egyetem is szerepelnek, valamint egy vezető magyar multinacionális telekommunikációs vállalat bevonása is folyamatban van.

A projekt célja az 5G Non-Terrestrial Network (NTN) technológiák valós űrkörnyezetben történő demonstrálása egy magyar fejlesztésű CubeSat műhold segítségével.

🛰️ A fejlesztés az ESA ARTES program és a Nemzetgazdasági Minisztérium támogatásával valósul meg.

A projekt 2026-ban indul, a műhold pályára állítása 2028-ban várható.

🌌Mauve pointed to calibration target light-years from Earth

🚀✨A huge step toward nominal operation!

Since its launch on 28 November 2025, the 16U Mauve satellite platform, built and operated by C3S, has successfully been progressed with commissioning with all major subsystems now powered and being operational.

🛰️The rapid commissioning procedure now allows to begin the scientific measurements and perform the first star observations.

🌟In February, we were already able to deliver the first spectra from the calibration target, eta Uma, a bright star 104 light-years from Earth to our customer Blue Skies Space.

We are so proud of being the platform provider for this fantastic CubeSat, the very first of its kind sending data to astronomers about the universe. 🌠🔬

More information about the first scientific data 👇

Mauve was pointed at its first calibration target, eta UMa, a bright star in the constellation Ursa Major, approximately 104 light-years from Earth.

🚀 WISDOM supported by ESA - European Space Agency NAVISP program is gradually entering its operational phase!

Since its November 28 launch, commissioning has been completed flawlessly — antennas deployed ✅, systems checked ✅, and ADCS nearly tuned ✅. The satellite is now slowly moving into active operation.

👀 Check out how WISDOM’s early mission phase unfolded — links in the comments!

✨ Stay tuned!
The unique 6U → 2×3U separation test is coming in March, followed by in-orbit technology demonstrations and advanced collision-avoidance trials.

🌌 Small satellites, big milestones.
