本SAE航空航天推荐规程（ARP）描述了无人系统（UMSs）专用术语以及这些术语的定义。它只关注专门用于开发、测试和其他有关UMSs活动的术语。它进一步关注UMSs的自主性和性能度量方面，并基于参与者的早期工作《无人系统自主水平（ALFUS）框架》（作为NIST特别出版物1011-I-2.0和NIST特别出版物1011-II-1.0出版）。这种做法也反映了与AIR5665的合作结果。本文档不包括社区中使用但可以通过常用词典定义理解的术语。正在计划进一步努力扩大术语的范围。 本航空航天推荐规程的目的是向无人系统社区传达一套通用术语和定义，可作为设计、开发、测试或以其他方式描述无人系统或其任何子系统的指南。

This SAE Aerospace Recommended Practice (ARP) describes terminology specific to unmanned systems (UMSs) and definitions for those terms. It focuses only on terms used exclusively for the development, testing, and other activities regarding UMSs. It further focuses on the autonomy and performance measures aspects of UMSs and is based on the participants' earlier work, the Autonomy Levels for Unmanned Systems (ALFUS) Framework, published as NIST Special Publication 1011-I-2.0 and NIST Special Publication 1011-II-1.0. This Practice also reflects the collaboration results with AIR5665. Terms that are used in the community but can be understood with common dictionary definitions are not included in this document. Further efforts to expand the scope of the terminology are being planned.The purpose of this Aerospace Recommended Practice is to communicate to the unmanned systems community a common set of terminology and definitions that can be used as guidance for designing, developing, testing, or otherwise describing an unmanned system or any of its subsystems.
