ISO / TS 20991，空间系统—小型航天器的要求，汇集了国际专业知识，详细阐述了小型航天器系统生命周期各个阶段的要求。
制定该文件的ISO技术委员会主席保罗·吉尔（Paul Gil）表示，预计未来五年内将有多达2 600架小型航天器投入使用，其中许多将由新运营商制造。
“ISO / TS 20991将为小型航天器开发人员以及发射人员提供极大的好处，通过提供最低要求，确保他们的安全以及碎片减缓，”他解释说。
ISO / TS 20991由ISO航空器和航天器技术委员会（ISO / TC 20）的空间系统和运营分技术委员会（SC 14）制定，其秘书处由美国的ISO成员ANSI承担。想获悉更多的国内外标准信息，请访问中国标准信息服务网（<http://www.sacinfo.cn>）。
Ready for lift-off: first international guidelines for small spacecraft just published
Space is all the rage, so it seems. The number of small spacecraft – including satellites – being manufactured has rocketed in recent years, and future forecasts are equally explosive. The first-ever internationally agreed requirements have just been published, enabling the industry to cruise even higher.
The small satellites industry is taking off. According to a recent report by SpaceWorks, an aerospace company focused on delivering cutting-edge flight and space technologies, 2017 showed a 205 % increase in small satellite launches compared to 2016, with a record number still awaiting launch. What’s more, forecasts for future spacecraft production, often by new entrants to the industry, look equally celestial.
But producing these spacecraft involves some very specific requirements that newcomers to the market may not be aware of. To help harmonize the sector, ISO has just published the first-ever international technical specification for small spacecraft, which states the minimum requirements that every small spacecraft needs to comply with regardless of its mission.
Bringing together international expertise, ISO/TS 20991, Space systems – Requirements for small spacecraft, details the requirements for various stages of the small spacecraft system life-cycle.
Paul Gill, Chair of the ISO technical subcommittee that developed the document, said that up to 2 600 small spacecraft are estimated to launch over the next five years, many of them made by new operators.
“ISO/TS 20991 will be of great benefit to small spacecraft developers, as well as launch operators, by providing the minimum requirements to ensure their safety and debris mitigation,” he explained.
“It covers everything from the design, launch, deployment, operation and disposal, which will also give newcomers to the industry a means to access space, typically the domain of large companies and governments.”
ISO/TS 20991 was developed by ISO technical committee ISO/TC 20, Aircraft and space vehicles, subcommittee SC 14, Space systems and operations, whose secretariat is held byANSI, ISO’s member for the USA.
