The City-Sized Hole in U.S. GPS Planning

Our society has become highly dependent on constant, real-time information about position, navigation, and timing. We typically access this information through cell phones or other devices that receive global positioning system (GPS) signals. Cities are particularly vulnerable to GPS failures and will become more so as Smart City initiatives produce results. Yet, we are missing opportunities to protect localities from potential disaster. This paper recommends efforts at all levels of government that could improve local government resilience, coordinate efforts, involve the private sector, and integrate these initiatives with federal planning for the future.
