About
The Umbra Power Package delivers a complete, integrated power solution for small satellites, combining a high-efficiency body-steered deployable (BSD) solar array, high-density lithium-ion battery modules, and an intelligent Power Management Unit (PMU). Flight-proven on Falcon 9 rideshare missions to LEO, the default flight configuration bundles one Umbra Steered Deployable Solar Array-120, two Umbra Battery Module-8S2P units, one Power Management Unit, and one Hold-Down and Release Mechanism, simplifying procurement and reducing integration complexity.
