Future growth in commercial and military space systems is constrained by technical problems associated with the frequency spectrum, by orbital congestion, and by costs stemming from proliferated terminals. The authors outline an Air Force-sponsored research project to design and develop a capability for predicting and analyzing the spectrum/orbital geometry requirements of current projected U.S. and international space-related systems. Two essential components of the project are a comprehensive space environment database and a computer analysis program. In combination, they will provide a resource for evaluating engineering and architectural designs, identifying and analyzing the impact of intentional and unintentional electromagnetic interference, and predicting probable saturation conditions in spectrum usage and satellite/orbital positions. The projected capabilities could provide an essential national resource for management decisionmaking and architectural planning on space-related programs. The U.S. Air Force Space Division is establishing a continuing project to utilize these capabilities.

This report is part of the RAND Corporation paper series. The paper was a product of the RAND Corporation from 1948 to 2003 that captured speeches, memorials, and derivative research, usually prepared on authors' own time and meant to be the scholarly or scientific contribution of individual authors to their professional fields. Papers were less formal than reports and did not require rigorous peer review.
