Construction of a multipurpose onboard computer for scientific investigations on the basis of system-forming elements

Abstract

The study deals with onboard computers for carrying out scientific investigations in space. The work is aimed at development of a concept of constructing an onboard computer based on system-forming elements for multi-purpose use. For investigations the analysis of application of computer technology in completed space projects and requirements for onboard computers in new experiments, as well as the analysis of the results of ground development of computer prototypes were used. A concept and architecture of an onboard computer on the basis of system-forming elements and apparatus of versatile design and manufacture of its components are developed. A technological prototype of a one-processor redundant onboard computer, an operational system of real time, debugging aids and onboard computer structure are created. The multipurpose onboard computer can be used for performing computer-aided experiments aboard spacecraft. The field of application covers space instrument-makingAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
