SpaceWire技术是随着航天器机载数据处理应用的需求而发展起来的。本标准为SpaceWire在未来广泛的机载处理系统中的应用提供了正式的基础。 SpaceWire的主要目标之一是在组件和子系统级别支持设备兼容性和重用。原则上，为光学仪器开发的数据处理系统 例如，可以通过拔下光学传感器并插入雷达传感器来用于雷达仪器。为一项任务开发的处理单元、大容量存储单元和下行链路遥测系统可以方便地用于另一项任务，从而降低开发成本，提高可靠性，最重要的是增加了可在有限预算内完成的科学工作量。交叉引用:EN 16601-00-01EN 16602-70-26EN 16602-70-08EN 16601-00购买本文件时可获得的所有现行修订均包含在购买本文件中。

SpaceWire technology has grown from the needs of spacecraft on-board data handling applications. This Standard provides a formal basis for the exploitation of SpaceWire in a wide range of future on-board processing systems. One of the principal aims of SpaceWire is the support of equipment compatibility and reuse at both the component and subsystem levels. In principle a data-handling system developed for an optical instrument, for example, can be used for a radar instrument by unplugging the optical sensor and plugging in the radar one. Processing units, mass-memory units and down-link telemetry systems developed for one mission can be readily used on another mission, reducing the cost of development, improving reliability and most importantly increasing the amount of scientific work that can be achieved within a limited budget.Cross References:EN 16601-00-01EN 16602-70-26EN 16602-70-08EN 16601-00All current amendments available at time of purchase are included with the purchase of this document.
