This work is being sponsored under the Naval Air Development Center's Indendent Exploratory Development program and was conceived as a three-year effort to analyze, design, fabricate and evaluate a new concept Nuclear Magnetic Resonance (NMR) gyroscope. This NMR gyro is being developed because of its potential to meet Navy needs for a small, high performance gyro with low cost of ownership for airborne and missile strapdown system applications. A transverse pumped NMR Gyro design embodying new concepts was developed to improve the performance capabilities of the NMR gyros. The primary improvement areas considered were signal-to-noise ratio, relaxation time and bias stability. The project was segmented into two phases. In the first phase, theoretical analyses were performed for the magnetic field coils, optics, magnetic shielding, gyro control and signal processing electronics and transverse AC pumping. Work under phase two currently underway included fabricating a working laboratory NMR gyro model utilizing the findings of phase one. This phase will include the evaluation of the signal-to-noise ratio, the relaxation time and the bias stability of the gyro. This presentation will discuss design objectives, theory and the current status of the in-house NMRG Program.
