The most important infrastructure of our daily lives is invisible: the Global Positioning System. GPS is a network of satellites that provides precise locations, which is integrated into all sorts of electronic devices, from self-driving cars and navigation systems to mobile phones. An accurate and reliable GPS system is also a national security concern, as GPS is a central component of modern weapons systems, air traffic controls, and even parts of the economy like agriculture. Not surprisingly, then, there are mounting questions about the security of GPS systems, and Japan, like all other major economies, must take them seriously.
