Abstract

On-orbit spacecraft servicing for military programs is examined. The military community appears to be somewhat reticent to embrace or, in some cases, to even consider on-orbit servicing. The civilian community appears enthusiastic about the potential of on-orbit servicing and the majority of economic studies of civilian missions show servicing strategies to be an attractive alternative to most expendable spacecraft strategies. A model called SATSERV is presented. This model can be used to conduct economic comparisons from an overall standpoint between expendable and servicing strategies. The model is implemented in a microcomputer spreadsheet format for rapid implementation and application along with ease of use by the manager. Four basic spreadsheet and mission scenarios are outlined and assumptions examined two low earth orbit mission profiles within the current STS operations envelope, one low earth orbit mission profile outside current STS operations capability and requiring a Teleoperator maneuvering System, and one geosynchronous mission scenario involving a space station and orbital transfer vehicle.
