A Distributed Computer System on ISS

The main objective of the Plasma Wave Complex (PWC, its Russian name is Obstanovka) system is investigating the dynamic processes in the magnetosphere and in the ionosphere, to which a wide range of electromagnetic phenomena accompany, from a steady, long term observing place on board of the International Space Station (ISS). (Plasma Wave Complex, PWC, archived page) The PWC Group is an international consortium comprising members from Bulgaria, Poland, Russia, Hungary and Ukraine. The computer system of PWC developed by our engineers is a distributed intelligence system consisting of three processors having their own local network. This network construction has the advantage of increased data acquisition throghput and dependability and satisfies the special electrical isolation requirements between the sensors and the on-board electronics set on ISS and in outer space. The computer system developed by our group stores data acquired from the eleven sensors of the PWC.
