A Methodology for Selection of a Satellite Servicing Architecture. Volume 1. Executive Summary

This study outlined a methodology to select a satellite servicing system and evaluated several initial system concepts. Future efforts to design and evaluate more detailed system concepts may build upon this study. The primary recommendation is to continue the application of the two phase systems engineering methodology to the alternative systems developed and modeled in the systems synthesis step. As these were preliminary models, there is insufficient detail to implement the systems identified, so additional refinements of the model are necessary. These refinements should address inclusion of additional performance indices, distinquish between mobile and fixed low G launch vehicles, improve the orbital mechanics relations, improve the representation of manned vs automated servicing, and improve the representation of life support requirements. Additionally, the value system needs refinement, such as incorporation of a more detailed objective hierarchy, and solicitation of high level decision maker preferences.
