According to the project №2323 «The development of the prototype of distributed fault tolerant on board computing system for satellite control system and the complex of scientific equipment» of the International Scientific and Technical Center the work on development of software and hardware parts of mentioned prototype is carrying out in the Keldysh Institute of Applied Mathematics of RAS and the Space Research Institute of RAS together with the Fraunhofer institute Rechnerarchitektur und Softwaretechnik (FIRST, Berlin, Germany) develop software and hardware parts for the prototype. The preprint describes the project’s hardware part implemented by now. Analysis of requirements to the on-board control complex is adduced. Block structure and composition of small spacecraft base complex are considered. Architecture and block-scheme of on-board computing system are defined.
