Orbital servicing and remotely manned systems

Abstract

The potential of the concepts and techniques of remotely manned aerospace systems to fully exploit the utility and benefits of orbital servicing is discussed. Orbital servicing has been shown to benefit the Space Transportation System by helping to satisfy spacecraft program objectives of long operating times on-orbit while reducing program costs. The wide range of servicer mechanisms postulated in the literature is reduced to two concepts which are used to generate a set of control system requirements. Three control mode alternatives - automatic, supervisory control, and remotely manned control - are introduced, defined, evaluated and each found wanting in certain areas. A combination of supervisory and remotely manned control is shown to overcome most problems.
