论文摘要
平方公里阵列（SKA）是下一代射电望远镜，由于其大光圈（约1平方公里）和高级仪器而以极高的灵敏度为特色。它将涵盖广泛的观察乐队，包括用于跟踪和通信深空任务的乐队。虽然航天器跟踪不是定义SKA技术规范的主要应用程序，但该设施可能在跟踪深空探针作为``专用'''深空跟踪网络的备份中发挥作用。本文介绍了SKA作为深空跟踪设施的可能应用以及SKA各种概念的主要相关技术规格。它是在2004年9月7日至9日在德国达姆施塔特（ESA-ESOC），ESA-ESOC，DARMSTADT，ESA-ESOC，ESA-ESOC，ESA-ESOC，ESA-ESOC的第三国际研讨会上介绍的。在过去的几年中，SKA概念已发展到更高的厌恶水平，目前处于实施阶段。本演示文稿中的许多具体考虑不再与SKA项目的实际状态相对应。但是，SKA应用程序的总体概念是通信和跟踪星际航天器的局部概念，并且此处介绍的一些方法仍然引起了潜在的深空任务的兴趣。
The Square Kilometre Array (SKA) is the next generation radio telescope distinguished by a superb sensitivity due to its large aperture (about one square kilometre) and advanced instrumentation. It will cover a broad range of observing bands including those used for tracking of and communications to deep space missions. While spacecraft tracking is not a main application defining the technical specifications of the SKA, this facility might play a role in tracking deep space probes as a backup to the ``dedicated'' deep space tracking networks. This paper presents possible applications of the SKA as a deep space tracking facility and major related technical specifications of various concepts of the SKA. It was presented at the 3rd International Workshop on Tracking, Telemetry and Command Systems for Space Applications, ESA-ESOC, Darmstadt, Germany, 7-9 September 2004. Over the past years, the SKA concept has developed to a much higher level of detalisation and is currently at the implementation phase. A number of specific considerations in this presentation no longer correspond to the actual status of the SKA project. However, the overall concept of the SKA applications for communication and tracking of interplanetary spacecraft remain topical, and some approaches presented here remain of interest for prospective deep space missions.
