This paper presents the design, testing, and validation of a ultra‐wideband (UWB) wireless solution to replace wired intra‐spacecraft communications with wireless communications. The system requirements are provided in the framework of the Eu:CROPIS mission and the wired intra‐spacecraft communication system is replaced with a two‐segment wireless network. As such, distinct sets of UWB gateways and nodes are prototyped to interface with the on‐board entities and properly handle the data transmission in the resulting spacecraft and payload wireless networks. To accomplish these tasks, a custom radio module integrated into the prototypes was designed to provide the appropriate UWB RF front‐end and run a custom‐built communication stack. The viability of the solution was tested in laboratory conditions. For the test scenarios, sensor data are acquired in the payload network and forwarded as SpaceWire packets over the spacecraft network. Experimental test results indicate the suitability of the proposed solution in terms of delay and data integrity for implementing intra‐spacecraft wireless communications.

一种用于传感器和SpaceWire数据的无线航天器内部传输的UWB解决方案
本文介绍了一种超宽带（UWB）无线解决方案的设计，测试和验证，该解决方案将无线航天器替换为有线航天器内部通信。Eu：CROPIS任务框架提供了系统要求，有线航天器内部通信系统被两段无线网络取代。因此，UWB网关和节点的不同集合被原型化以与机载实体进行接口，并正确处理所得航天器和有效载荷无线网络中的数据传输。为了完成这些任务，已将集成到原型中的定制无线电模块设计为提供适当的UWB RF前端并运行定制的通信堆栈。在实验室条件下测试溶液的生存力。对于测试方案，传感器数据在有效载荷网络中获取，并通过航天器网络作为SpaceWire数据包转发。实验测试结果表明，所提出的解决方案在延迟和数据完整性方面是否适合实施航天器内部无线通信。
