End-to-enddesign through operations

C3S develops and manufactures its own satellite platforms. It also provides integration, testing and mission support.

Did you know that Hungary has been building successful satellites for years?

Redundant subsystems, qualification testing and flight-proven electronics support mission continuity. C3S also engineers the interface between platform and payload, so the spacecraft works as an integrated system.

Large-satellite technology in small satellites

Radiation monitoring, onboard AI, agricultural Earth observation and stellar spectroscopy build on a shared platform heritage. New programmes extend that work into space-traffic safety and communications.
