Study Finds Ligado Won’t Harm Most GPS Receivers
A report from the National Academies of Sciences, Engineering, and Medicine questions the effects of Ligado Networks on GPS receivers.

Since the U.S. Federal Communications Commission (FCC) in 2020 authorized Ligado Networks to use radio frequency spectrum near GPS and satellite service bands, aviation and other industry groups have asked the FCC to rescind the order. However, a report requested by Congress raises new questions about whether Ligado’s operation in the L-band will deleteriously affect GPS receivers used in aviation and by the military. The report was conducted by the National Academies of Sciences, Engineering, and Medicine.
