The Solar Maximum Mission (SMM) is the first satellite to use the Multimission Modular Spacecraft (MMS) base module. The Modular Power Subsystem (MPS) is one of the major subsystems of the MMS. The in-flight performance of the MPS and the other components of the Electrical Power System (EPS) for the first 18 months of the mission is discussed. Details of performance such as solar array current and voltage degradation, Standard Power Regulator Unit (SPRU) efficiency, peak power tracking accuracy, battery charge to discharge ratio, battery voltage degradation and battery differential voltage characteristics are discussed.
