Robotic servicing of EOS instruments

Abstract

This paper addresses robotic servicing of the Earth Observing Satellite (EOS) instruments. The goals of implementing a robotic servicing system on EOS would be to maintain the instruments throughout the required mission life and minimize life-cycle costs. To address robot servicing, an initial design concept has been developed which will be applied to a representative EOS instrument. This instrument will be used as a model for determining the most practical level of servicing of its parts, and how to design these parts for robot servicing. Using this representative EOS instrument as a model, a generic design scheme will be developed that can be applied to all EOS instruments. The first task is to determine how to identify which parts must be designed for robot servicing. Next, the requirements imposed on the instruments and the servicing robot when designing for robot serviceability must be examined.
