SPS Built of Lunar Materials. Space Studies Institute RFP 1984

The receiving device on Earth (rectenna or other) is not a part of this study, except as much as its efficiency and the stated power density limitations may affect the satellite design. In producing the satellite design, the following are required within the scope of the study: a) Estimates (with calculations or references) of key technical parameters and reasons for choices. b) Explanation of trade-offs leading to design decisions. c) Identification of potential technology problems, and ways to avoid new development as far as possible. d) Concept description. e) Rationale for concept choice and for sizing choice, if a one- point design is chosen. f) Description of recommended design, with drawings, mass summaries by components and by chemical elements, and supporting calculations. The mass summaries must be subdivided into lunar-available elements and elements which must be obtained from the Earth. I. METHODOLOGY Throughout the study the contractor shall employ certain methodologies deliberately selected to enhance the ultimate usefulness of the study. These include the following: 1) All explicit assumptions shall be justified, or if they rely on previous work, that work shall be fully referenced and the assumptions verifiable and traceable in the literature. In the case when several assumptions are used to derive a subsequent result, the input assumptions must be explicitly stated and referenced and the path to the final result clearly spelled out. In summary, the analysis must be transparent and all results fully traceable so that they can be readily verified at a later time.
