Analysis of Potential Interference Issues Related to FCC Order 20-48
Requested by Congress in P.L. 116-283, the William M. (Mac) Thornberry National Defense Authorization Act for Fiscal Year 2021, this new report from the National Academies of Sciences, Engineering, and Medicine, reviews Federal Communications Commission 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. It considers how best to evaluate harmful interference to civilian and defense users of GPS, the potential for harmful interference to GPS users and Department of Defense activities, and the effectiveness and feasibility of the mitigation measures proposed in the FCC order.
