In the preliminary design of spacecraft, spreadsheets are often used to scale and size components. While offering some benefits, using spreadsheets does have some drawbacks. In particular, since time is typically not one of the input values, overly conservative designs can result because scheduling issues are not considered. To overcome this problem, the Space Systems Concepts Division is developing a time dependent, virtual spacecraft simulation system. Since the performance of many components on the spacecraft are sensitive to the attitude of the spacecraft, a method or function is needed to determine the attitude of a part. Thus, the primary goal of this research was to develop a software module that calculates the attitude of an arbitrary part on the spacecraft. This module is then used by subsystem engineers, e.g. the power subsystem, to compute the attitude relative to the spacecraft, the sun, the Earth, or a user specified target.
