Assured Nanosecond Accuracy Wireless Network Synchronization in GPS denied environment

Researchers of USC Viterbi School of Engineering, Segura, Niranjayan, Hashemi and Andreas Molisch, have experimentally demonstrated the first wireless network synchronized with nanosecond accuracy. They have developed a prototype, consisting of four nodes that synchronize to each other with an accuracy of approximately three nanoseconds. They also introduced a scalable protocol, which they call the “Blink” algorithm that extends the same accuracy to hundreds or even thousands of wireless devices.

There are a variety of applications that require very high timing synchronization accuracy, coordinated jamming of enemy military receivers, distributed beam forming, fine grain localization, tracking, and navigation, require timing synchronization with nanosecond precision or even better.
