本文总结美国国家射电天文台等与非对地静止轨道卫星星座协调工作，阐述频谱干扰避免方案与运营数据共享系统案例，强调合作经验及ODS系统对其他频谱利益相关者的潜在应用。
AI 中文摘要
近年来，随着频谱使用需求的增加，特别是非对地静止轨道卫星系统用于宽带互联网和蜂窝服务的扩展时，位于偏远地区的射电天文台面临着来自无处不在的卫星下行链路的有害射频干扰（RFI）暴露日益增加的挑战。在美国国家科学基金会的帮助下，美国国家射电天文台和射电天文学界率先与商业非对地静止轨道运营商合作，开发不同的协调技术，以减轻这些下行链路信号对射电天文学科学观测的影响。本文总结了正在进行的协调工作、频谱干扰避免方案，以及射电天文学与非对地静止轨道运营商之间的运营数据共享（ODS）系统的社区参与案例研究。我们强调了从这些合作中学到的一些重要经验教训，以及ODS系统在其他潜在频谱利益相关者中的潜在应用。
英文摘要
With the increased demand for spectrum usage in recent years, particularly with the expansion of NGSO satellite systems for broadband internet and cellular services, radio astronomy observatories located at remote sites have been faced with the challenge of increasingly detrimental RFI exposure from ubiquitous satellite downlinks. With the help of the U.S. NSF, NRAO and the radio astronomy community have spearheaded collaboration efforts with the commercial NGSO operators to develop different coordination techniques to alleviate the impacts of these downlink signals in radio astronomy scientific observations. This paper summarizes the ongoing coordination efforts, spectrum interference avoidance schemes, and a case study on community participation of the Operational Data Sharing (ODS) system between RAS and NGSO operators. We highlight some of the essential lessons learned from these collaborations and potential application of the ODS system to other potential spectrum stakeholders.
