Nuclear Magnetic Resonance Gyroscope: For DARPA’s Micro-Technology for Positioning, Navigation and Timing Program

M. Larsen, M. Bulatowicz

Abstract:	The navigation grade micro Nuclear Magnetic Resonance Gyroscope (µNMRG) being developed by Northrop Grumman is currently in the fourth and final phase of the DARPA-MTO Navigation Grade Integrated Micro Gyro (NGIMG) task as part of the Micro-Technology for Positioning, Navigation and Timing (micro-PNT) program. The µNMRG technology is pushing the boundaries of size, weight, power, and performance of rotation sensor technology, allowing new small platform applications of navigation grade Inertial Navigation System (INS) technology. The µNMRG technology has no moving parts, and the magnetic resonance process at the heart of the sensor is inherently vibration and acceleration insensitive. This makes it an ideal match for small platform high dynamics applications. The Phase 4 physics package is 10cm3 in volume for a single axis and is anticipated to meet the final NGIMG performance goals of 0.001°/?hr angle random walk, 0.01°/hr bias instability, greater than 500°/s full scale rate, and less than 50ppm scale factor stability. Information on the sensor basics of operation, task performance goals, current status, and demonstrated performance in testing at Northrop Grumman as well as independent testing at the U.S. Army Aviation and Missile Research Development and Engineering Center (AMRDEC) will be presented.
