    Abstract

    The SpaceWire data-handling network is being used on many ESA, NASA and JAXA spacecraft and by other space agencies. research organisations and space industry across the world. SpaceWire is designed to connect together high data-rate sensors, processing units, memory sub-systems and the down link telemetry sub-system. It provides high-speed (2-200 Mbits/s), bi-directional, full-duplex, data links which connect the SpaceWire enabled equipment. Networks can be built to suit particular applications using point to point data links and routing switches. SpaceWire is supported by several radiation tolerant ASICs designed by or for ESA, NASA and JAXA, and extensive test and development equipment is available. This paper provides an introduction to SpaceWire aimed at project managers and system engineers. It describes how SpaceWire can be used to implement data-handling architectures matched to mission requirements and illustrates this with some examples. Finally an overview of the latest developments in SpaceWire is included. (C) 2009 Published by Elsevier Ltd.
