    Military researchers have launched several projects in recent years to find alternatives to GPS. With so many location and navigation systems—from those in smart phones to aircraft—dependent on the Global Positioning System, the military is concerned about the threat of GPS service being lost because of natural disaster or manmade attacks.

    Efforts have included an Army project to use portable sensors to track soldiers’ movements that uses gyroscopes, accelerometers and a master clock to provide navigation and an anti-ship missile that doesn’t need GPS to zero-in on its target.

    The Defense Advanced Research Projects Agency is now working on another tool—a next-generation palm-size atomic clock that would be 1,000 times more accurate than current models and provide the ultra-precise timing necessary to maintain position information in the event GPS goes out.
