CDH (Command & Data-Handling)

CDH (Command & Data-Handling)

The CDH design uses a SmartFusion 2 System on Chip with an ARM Cortex M3 processor. The main functions of the CDH include collecting and storing housekeeping data from all subsystems and science data from the payload. Additionally, it facilitates subsystem configuration and houses a Real-Time Counter (RTC) for precise time tagging of data.
