→Common Power values for Cubesats in Industry
==The Basics==
==The Basics==
Satellite power modules are widely known as '''electrical power systems, or EPS'''. If you are purchasing Cubesat components as a kit, the EPS will come as a self contained unit, with outputs for voltage bus distribution and battery connnections. The EPS can be broken down conceptually into four smaller blocks. They are the [[#Power Sources]], the [[#Energy Storage]], the [[#Power Distribution]], and the '''Power Regulation and Control''' modules.
