US: Northrop Grumman has developed and demonstrated a new micro-Nuclear Magnetic Resonance Gyro (micro-NMRG) prototype for the Defense Advanced Research Projects Agency (DARPA), providing precision navigation for size- and power-constrained applications.

The development of a hermetically sealed micro-NMRG that meets precision navigation requirements along with a successful prototype demonstration marks the fourth and final phase of DARPA”s Navigation-Grade Integrated Micro Gyroscopes (NGIMG) programme.

Northrop Grumman”s micro-NMRG technology uses the spin of atomic nuclei to detect and measure rotation, providing comparable performance to a navigation-grade fiber-optic gyro in a small, lightweight, low power package.

Additionally, the gyro has no moving parts and is not inherently sensitive to vibration and acceleration. The technology can be used in any application requiring small size and low power precision navigation, including personal and unmanned vehicle navigation in GPS-denied or GPS-challenged locations.

“Our miniature gyro technology offers unprecedented size, weight and power savings in a compact package, exceeding program requirements,” said Charles Volk, vice president of Northrop Grumman”s Advanced Navigation Systems business unit. “This important technology can help protect our warfighters by offering highly accurate positioning information, regardless of GPS availability.”
