Sub-systems

The five on-board subsystems, each an independent FreeRTOS binary. They share no memory: what crosses a subsystem boundary is an 8-byte CAN frame, except for bulk science, which goes over SpaceWire.

DHS — the Data Handling Sub-System
TTC — Telemetry, Tracking and Command
ADCS — Attitude Determination and Control
EPS — the Electrical and Power Subsystem
PAYLOAD — the Science Payload
