This study was performed to model on-orbit servicing (OOS) of a pre- existing Low Earth Orbit and geostationary constellation. A conceptual model of each spacecraft was developed to determine mass and power allocation required based on the mission of the spacecraft. An OOS mass was added to the spacecraft which represented the mass of the components necessary to allow the spacecraft to be docked with. The servicing missions modeled were refueling, replacement of parts, and relocation. The driving factor of cost was sensitivity to OOS mass. For most constellations, OOS was not cost effective unless the OOS mass was very low. 15.
