Payload servicing of a 17-instrument Polar Platform complement is determined from the available design data, reliability of the platform subsystems, and the servicing interval of each component. On-orbit and ground servicing analytical background and cost modeling are summarized. The most suitable grouping of the scientific and commercially biased instruments and their servicing needs is discussed. It is suggested that dedicated platforms are more cost effective in terms of servicing lifetime. The Orbital Replacement Unit philosophy is considered and its effect on basic design concepts are reflected in the robotic and extra vehicular activity approach.
