WASHINGTON: The U.S. Defense Department said a study released Friday shows Ligado<\/a> Networks' planned nationwide mobile broadband network will interfere with military global positioning system receivers (GPS<\/a>) receivers.

The Federal Communications Commission in April 2020 voted to permit Ligado to deploy a low-power network. In January 2021, the FCC rejected a bid by U.S. government agencies to put its decision on hold.

The National Academy of Sciences, Engineering, and Medicine report released Friday warned some Iridium Communications<\/a> mobile satellite services \"used by the U.S. Department of Defense and others will experience harmful interference under certain conditions and warned some high-precision devices sold before about 2012 \"can be vulnerable to significant harmful interference.\"

The Defense Department said the study is consistent with its view that \"Ligado's system will interfere with critical GPS receivers and that it is impractical to mitigate the impact of that interference\" and noted the study found FCC's proposed mitigation and replacement measures \"are impractical, cost prohibitive, and possibly ineffective.\"

Ligado argued the report found \"a small percentage of very old and poorly designed GPS devices may require upgrading.\"

It noted that with the FCC it established a 2020 program \"to upgrade or replace federal equipment, and we remain ready to help any agency that comes forward with outdated devices. So far, none have.\"

Ligado said it hopes U.S. agencies \"will stop blocking Ligado's license authority and focus instead on working with Ligado to resolve potential impacts relating to all DOD systems.\"

Iridium said the study shows \"that Ligado's proposed operations will cause harmful interference.... Iridium urges the FCC to take swift action to reverse the order before Ligado starts its technical demonstrations this fall.\"

The FCC did not immediately comment.

The study also found Ligado's network \"will not cause most commercially produced general navigation, timing, cellular, or certified aviation GPS receivers to experience harmful interference.\"

In May 2020, the U.S. Commerce Department filed a request with the FCC on behalf of executive branch agencies, including the Defense and Transportation departments, arguing it would cause \"irreparable harms to federal government users\" of GPS. The report called on FCC and Commerce to conduct joint testing and \"a more collaborative approach to resolving spectrum issues.\"

五角大楼警告Ligado宽带网络的GPS干扰

联邦通信委员会在2020年4月投票允许Ligado部署一个低功耗网络。2021年1月,联邦通信委员会否决了美国政府机构收购搁置其决定。

华盛顿:美国国防部说周五公布的一项研究显示Ligado网络的计划在全国范围内移动宽带网络将干扰军事全球定位系统接收器(全球定位系统(GPS))接收器。

联邦通信委员会在2020年4月投票允许Ligado部署一个低功耗网络。2021年1月,联邦通信委员会否决了美国政府机构收购搁置其决定。

美国国家科学院、工程和医学周五发布的报告警告说铱星通信移动卫星服务”被美国国防部和其他将经历有害干扰在一定条件下,并警告一些高精度设备售出约2012”可能是容易受到很大的有害干扰。”

国防部说,这项研究是符合其认为“Ligado系统将干扰关键GPS接收器,它是不切实际的减轻干扰”的影响,研究发现FCC提出的缓解和替代措施”是不切实际的,成本高昂,可能无效的。”

Ligado认为该报告发现“一小部分很老,设计糟糕的GPS设备可能需要升级。”

与FCC指出,它建立了一个2020项目“联邦设备升级或替换,我们仍然愿意帮助任何机构,推进过时的设备。到目前为止,都没有。”

Ligado表示,希望美国机构”将停止阻止Ligado执照权威,而是更多地关注与Ligado合作解决相关的潜在影响所有国防部系统。”

铱说研究显示“Ligado提出的操作会导致有害干扰....铱敦促FCC迅速采取行动扭转今年秋季订单Ligado开始前技术示威。”

FCC没有立即发表评论。

研究还发现Ligado的网络“不会导致大多数商业化生产通用导航、时间、细胞,或注册航空GPS接收器经验有害干扰。”

2020年5月,美国商务部提起请求与FCC代表行政分支机构,包括国防和交通主管部门,认为这将导致不可挽回的危害联邦政府用户的GPS。报告呼吁FCC和商务进行联合测试和“更协作的方式解决问题。”
