ExoTerra’s SEP module is a full spacecraft bus in 6U or 12U built around our propulsion module. To the propulsion system it adds a lightweight chassis, 2 deployable solar arrays on a single-axis continuous-rotation gimbal, battery and associated battery management electronics, and a power distribution card.
The typical 6U configuration shown below has up to 2.5 U volume available for customer-specific operations and payload components, and can be augmented with deployable radiators and enhanced power storage. The full payload-ready version of the SEP module includes all components required for a complete spacecraft, covering guidance and navigation, attitude control, and command and data handling, with approximately 1U reserved for payloads (actual volume depending on customer-selected spacecraft options).
