Audio-Visual Satellite Instruction system (AVSIN) for USA - preliminary considerations
Requirements were determined analytically for the man machine interface for a teleoperator system performing on-orbit satellite retrieval and servicing. Requirements are basically of two types; mission/system requirements, and design requirements or design criteria. Two types of teleoperator systems were considered: a free flying vehicle, and a shuttle attached manipulator. No attempt was made to evaluate the relative effectiveness or efficiency of the two system concepts. The methodology used entailed an application of the Essex Man-Systems analysis technique as well as a complete familiarization with relevant work being performed at government agencies and by private industry.
The analysis required to estimate auxiliary-propulsion system requirements for a mission which includes tipoff rate reduction, acquisitions, disturbance torques, orbital disturbances, and spacecraft commanded maneuvers is presented. The comparison of several candidate auxiliary-propulsion systems and system combinations for an advanced applications technology satellite (ATS-H) is described. A generalized auxiliary-propulsion system tradeoff, based on mission cost effectiveness criteria, is examined. The specific mission assumptions for the ATS-H spacecraft are included, along with a discussion of the sensitivity of the final selection to these assumptions.
Discussion of cooperative arrangements and agreements among NASA, the Department of Commerce, and other governmental agencies in developing and operating meteorological satellite systems. The development of present interagency agreements and their conditions are discussed along with differences from the usual NASA program introduced by the supplier-client relationship between NASA and NOAA (National Oceanic and Atmospheric Administration).
