SUBSYSTEMS
Get to know our satellite subsystems
Our platforms employ in-house developed, powerful & robust subsystems for the success of your mission.
STRUCTURES
3-12U Structures (STRU)
C3S offers two different designs when it comes to structures so that every customer can find the right solution. The one used during the Radcube mission has a stackable design along with unique wiring system, while the other design allows flexible payload and subsystem positioning for optimal configurability.
