Some considerations for Space Tug launch site support operations.

The study reported was undertaken to investigate the requirements placed on the Space Tug by the ground operations. On the basis of the results obtained, it will be possible to consider in future Tug systems studies the full spectrum of both ground and flight operations requirements in defining selected Tug configurations. The central core of the study consists of a functional analysis of ground operations during the Tug turnaround. Electronic system studies were initiated concurrently with the functional analysis study phase to evaluate interrelationships between ground and vehicle checkout and fault isolation capability.
