CDH-110
The BST CDH system consist of two main parts: the OBC-110 and the ACC-110. The OBC-110 is responsible for scheduling all tasks and coordinating TMTC functions of the bus whereas the ACC-110 which is integrated in the same housing runs the attitude algorithm and connects to all ADCS components. Optionally an auxiliary processor can be attached to the OBC-110 that allows centralized operation via a Linux operation system. The BST CDH has space heritage since 2015.
