Space Systems Cost Study (for Microcomputers)
Abstract
The study objective was to develop a methodology and automated database/model that would enable DARPA to evaluate 'low cost satellite' programs and appropriate cost reduction approaches. The initial step in this cost study was to derive an estimate for developing and producing a 'light' satellite under 'business as usual' conditions. These conditions include a 'start from scratch' philosophy and all the traditional operating procedures and documentation associated with building a reliable spacecraft. The goal of the baseline cost modeling effort was to determine a cost estimate that would represent the current culture of the satellite industry. This culture generally follows a 'business as usual', 'start from scratch' development approach. The baseline program emulates a typical USAF Space Division Mil-Std 1450B-type spacecraft. The vehicle mission type used for the analysis is a communications-radio relay spacecraft. Cost estimates and trades to the baseline developed as a result of this study, are applicable to any spacecraft that contains a similar functional mix of structure, payload, and electronics. The RCA PRICE H Hardware model was selected as the cost estimating tool for all items except software, which was estimated using Martin Marietta's in-house model, PCEM (software Parametric Cost Estimating Model). The model is written in the PASCAL programming language for implementation on an IBM PC or compatible. Diskette. (EDC)
