Review of FCC Order 20-48 Authorizing Operation of a Terrestrial Radio Network Near the GPS Frequency Bands Report Release Webinar

Public release briefing slides updated Nov. 8, 2022

About

In April 2020, the Federal Communications Commission issued order FCC 20-48, which authorized Ligado Networks LLC to operate a low-power terrestrial radio network adjacent to the Global Positioning System (GPS) frequency band. The FY2021 National Defense Authorization Act asked the National Academies to provide an independent technical review of this FCC Order. For more information, please visit the project website.

The report considers how best to evaluate harmful interference to civilian and defense users of GPS, the potential for harmful interference to GPS users and the Department of Defense activities, and the effectiveness and feasibility of the mitigation measures proposed in the FCC order.

Please join us for a public release webinar to learn more about the report's conclusions from members of the committee.

Note added November 8, 2022:

As detailed in the committee’s report and in the comments made verbally during the public briefing at which this slide deck was used, the committee makes an explicit distinction between the FCC-defined regulatory term ‘Harmful Interference’ and the committee’s use of the term ‘harmful interference’ in describing its task and in its conclusions.

To avoid any confusion that might come from only looking at the slide deck and not having access to the verbal delivery, these slides have been annotated to clearly indicate which term is being used in each circumstance.
