The National Academy of Sciences has released its long-awaited study on the effects of Ligado Networks operating a terrestrial network next to spectrum currently used for the Global Positioning System. Earth-based Ligado’s signals could easily, albeit unintentionally interfere with a range of GPS receivers. The National Academy of Sciences concludes that high-precision receivers will experience “significant harmful interference from Ligado emissions as authorized by the FCC.” These include receivers for construction, agriculture, and surveying. The National Academies’ report states that Ligado interference might occur precisely when these aircraft are trying to rescue people who have crashed in low-visibility conditions. The National Academy of Science study underscores what the Executive Branch concluded over two years ago: Ligado transmissions will interfere with the operation of infrastructure, public safety, and national defense.
