    Abstract: An accelerometer system can include a sensor element comprising first and second proofmasses, the first proofmass accelerating in a first direction and the second proofmass accelerating in a second direction opposite the first direction in response to an external acceleration. A force rebalance controller applies control signals to at least one control element to provide a first force to accelerate the first proofmass toward a first null position and to at least one control element to provide a second force to accelerate the second proofmass toward a second null position. The force rebalance controller can also generate opposite polarity first and second output signals associated with respective displacements of the first and second proofmasses relative to the respective first and second null positions. An acceleration component calculates the external acceleration based on the first and second output signals.

    Abstract: One embodiment of the invention includes an atom beam gyroscope system. The system includes an atom beam system that generates an atom beam comprising alkali metal atoms along a length of a detection region orthogonal to a sensitive axis. The system also includes a detection system comprising a detection laser and photodetector. The detection laser can generate an optical detection beam that illuminates the detection region to pump the alkali metal atoms. The photodetector can measure an optical absorption of the optical detection beam by the alkali metal atoms in the atom beam and to generate an intensity signal associated with the measured optical absorption. The system further includes a gyroscope sensor configured to calculate rotation of the atom beam gyroscope system about the sensitive axis based on a magnitude of the intensity signal due to a Doppler-shift in energy of the alkali metal atoms in the atom beam.

    Abstract: One embodiment includes a nuclear magnetic resonance (NMR) gyroscope system. The system includes a vapor cell that encloses an alkali metal and a gyromagnetic isotope. The system also includes a magnetic field source that generates a magnetic field aligned with a sensitive axis of the NMR gyroscope system and which is provided through the vapor cell to cause the alkali metal and the gyromagnetic isotope to precess. The system also includes a laser that generates an optical beam that polarizes the alkali metal in the vapor cell to facilitate the precession of the alkali metal and the gyromagnetic isotope. The system further includes an angular rotation sensor configured to calculate a rotation angle about the sensitive axis based on a measured characteristic of a detection beam corresponding to the optical beam exiting the vapor cell, the characteristic being associated with the precession of the gyromagnetic isotope.
