The Power Subsystem (EPS) is responsible for the generation, storage and distribution of the power on-board the spacecraft. This subsystem is composed of the following items.
Main power management board (EPS).
5 x Solar panels.
- 2 x Batteries.
Like happened with the TTC, the EPS was also subjected to a number of modifications that lead to a board configured directly for Humsat-D.
These changes from the original board were mainly motivated by testing and mission requirements.
