The power generation and storage of the Magsat power system is examined along with other system functions. An array of silicon solar cells mounted on four panels, each with two curved segments generates the electrical power. The power output of the solar array is measured as a function of the angle psi between the +B spacecraft axis and the sun-earth line. The battery contains 12 series connected 8 ampere-hours nickel cadmium cells operating at a nominal voltage of 16.7 V. A lightweight shunt regulator is designed to dissipate excessive solar array power as heat. A block diagram of the Magsat power subsystem is presented with the loads divided into critical and noncritical categories.
