Lack of US Leadership Seen as Big Hurdle to More Resilient GPS

Chips message robust authentication (Chimera) technology would protect and augment GPS signals, but the biggest hurdle to more resilient positioning, navigation and timing capabilities is the dearth of U.S. leadership and concern, blogged Resilient Navigation and Timing Foundation President Dana Goward Wednesday. Concerns about potential GPS spoofing date back decades, and Chimera was proposed in 2003, but only now is the federal government looking at it, said Goward. Even if Chimera is implemented, the lack of standards for GPS receivers used in critical applications means it could be decades before legacy GPS receivers are finally all phased out, he said.
