DARPA is developing a hyper-precise alternative to GPS

The U.S. government sympathizes these modern day plights – because they affect our military – and has decided to take matters into its own hands by way of DARPA (Defense Advanced Research Projects Agency) to develop a radical alternative to GPS with unjammable signals that won’t disappear in blind spots. 

The navigation system, with its advanced positioning and navigation-tracking, is aimed at giving the armed forces a far more reliable strategic advantage than GPS, which, while has tremendously helpful, is not foolproof. GPS is highly susceptible to offensive jamming measures and is obfuscated in remote corners of the world devoid of democracy such as caves and dense jungles.
