EPS Second Revision

The second version of the Electrical Power System (EPS V2) has been successfully tested. The EPS is a critical component that provides power to all satellite subsystems. Recent testing has confirmed that EPS V2 meets its high-level requirements for power generation and storage, ensuring MARMOTSat can remain operational in its target Sun-Synchronous Orbit.

A key outcome of this iteration is an improved efficiency over the V1 design, which allows for more power generation and less heat generation. Based on the testing of this revision, only minor modifications are anticipated for the final flight revision.

This result marks significant progress for the MARMOTSat project. Further updates on the flight version of the EPS will be provided as development continues.
