ARLINGTON, Va. – U.S. military researchers are asking industry to develop relatively simple portable photonic integrated circuits (PICs) for high-performance position, navigation, and timing (PNT) devices as an alternative to the Global Positioning System (GPS) for when GPS signals are not available.

Officials of the Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., issued a solicitation late last month for the Atomic-Photonic Integration (A-PhI) project that seeks to reduce the complexity of trapped-atom high-performance PNT devices.

This project also seeks to develop a trapped-atom gyroscope -- a matter-wave analogue of the interferometric fiber-optic gyroscope (FOG).

Reliable PNT is a critical resource for all U.S. military missions, and influences areas such as communications, navigation, reconnaissance, and electronic warfare (EW), DARPA officials explain
