Substructural models, described in earlier reports in this series, are reduced in size with very little loss in accuracy. These models are then combined to form a structural model for the overall spacecraft. This model is, in turn, reduced in size (i.e., in number of coordinates) with only a small penalty in accuracy. 'Modal cost analysis' is shown to be an effective technique for this purpose. Two specific models are recommended in this report, and all system data is given in the appendices for each of these models. The model appropriate to control system design includes four elastic modes; the final data for this model are tabulated in Appendix C. For control system evaluation, a model that incorporates an additional seven modes is recommended; the data for this model are tabulated in Appendix D"--Summary, page iii.
