U.S. Secretary of Defense Wants to Move Past GPS to MEMS-Based Navigation, PNT Experts Doubtful

Ashton Carter, the new U.S. Secretary of Defense has been making clear he supports moving past GPS to a disbursed network based on microelectromechanical systems or MEMS for position, navigation, and timing (PNT) information.

Carter, who was tapped to lead the Pentagon in February, appears to have first publically floated the idea a year ago, about six months after leaving the Department of Defense (DoD), where he had served most recently as deputy secretary of defense, a role that included cochairing the interdepartmental National Space-Based PNT Executive Committee.
