About
The BST CDH-110 system is a Command and Data Handling solution for satellite platforms, consisting of two primary components: the OBC-110 and the ACC-110. The OBC-110 is responsible for managing and scheduling all tasks, as well as coordinating Telemetry, Tracking, and Command (TMTC) functions for the satellite bus. The ACC-110, integrated within the same housing, executes attitude algorithms and interfaces with all Attitude Determination and Control System (ADCS) components. An optional auxiliary processor can be connected to the OBC-110, enabling centralized operation through a Linux operating system. The system offers communication security features including authentication and encryption. It has space heritage dating back to 2015.
