CDH-110 image


The CDH-110 system consists 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.

OBC-110 & ACC-110 characteristics:
- Dimension: 176x94x69 mm³
- Mass: 815 g
- Data Interfaces: 20x RS422
- Process Power: 90 MIPS
