Abstract
One embodiment of the invention includes a nuclear magnetic resonance (NMR) gyroscope system. The system includes a gyro cell that is sealed to enclose an alkali metal vapor, a first gyromagnetic isotope, a second gyromagnetic isotope, and a third gyromagnetic isotope. The system also includes a magnetic field generator configured to generate a substantially uniform magnetic field that is provided through the gyro cell to cause the first, second, and third gyromagnetic isotopes to precess. The system further includes an angular rotation sensor configured to measure a rotation angle about a sensitive axis of the NMR gyroscope system based on measured precession angles of the first, second, and third gyromagnetic isotopes.
