Abstract : A technique is presented for estimating development and procurement costs for space power subsystems. The data employed in deriving the costing relationships primarily stem from the 1966 DOD Space Power Study and the Aerospace Corporation's experience and data sources. These sources represent the most current and extensive survey of both costs and technologies of the space power field that exist today. Energy sources and power conversion schemes are analyzed separately and jointly in feasible combinations of power systems applicable to future space missions. Cost-scaling factors are provided for integrating each type of power subsystem into a payload. Estimated projections of space power subsystem costs for fifteen years into the future are also provided. Due to the vast uncertainty involved in estimating future system costs, all pertinent details of the estimating procedure are given so that the technique can be readily altered by replacing any of the parameters that appear questionable.
