Federal officials said Wednesday that recent tests of start-up LightSquared Inc.’s proposed national wireless-Internet network showed it would still knock out a “majority” of GPS devices. A report in The Wall Street Journal quotes Anthony Russo, director of the National Coordination Office for Spaced-Based Positioning, Navigation and Timing, a government and industry advisory board, as saying government tests showed that “LightSquared signals caused harmful interference to the majority of…general purpose GPS receivers.”
