Command and Data Handling System (CDH)
Summary
The BST CDH system consist of two main parts: the OBC-100 and the ACC-100. The OBC- 100 is responsible for scheduling all tasks and coordinating TMTC functions of the bus whereas the ACC-100 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-100 that allows centralized operation via a Linux operation system.
