The purpose of this study is to introduce and propose design structure matrix in the conceptual designing phase for CubeSats. The designing process began from eliciting performance parameters and culminated in the formation of design structure matrix, determining dependencies and finally their optimization. Optimization of design structure matrix includes achieving designing sequence, control of interferences and designing parameters determined for the satellite. This method has been applied on a CubeSat with three units. Designing a three-unit CubeSat includes 61 performance parameters. These parameters have dependencies which have been considered in designing design structure matrix. After optimization of the qualitative relationships, quantitative designing of the parameters were conducted. After determining characteristics of the parameters and selection of the needed parts, technical budgets were proposed. Finally, the technical budgets were compared with the statistical data of the similar satellites and part selection and technical budgets were confirmed.
Key words: CubeSat, design structure matrix, systematic designing, performance parameters, controlling requirements and interferences
