摘要： A chip-scale gyrometric apparatus is disclosed. In embodiments, the chip-scale gyrometric apparatus includes a dielectric substrate and an antenna element attached thereto for receiving an inbound signal having an initial phase. The apparatus includes a splitter for splitting the inbound signal into two equivalent signals, and two coils connected to the splitter. The first coil carries one of the split signals in a clockwise (CW) path relative to a rotational axis, while the second coil carries the other split signal in a counterclockwise (CCW) path relative to the same axis. An integrated circuit (IC) on the substrate and connected to the first and second coils measures a phase shift between the first and second signals (e.g., deviation from the initial phase) based on their respective CW and CCW paths and determines, based on the measured phase shift, a degree of rotation relative to the common rotational axis.

摘要： A gyroscope sensor is provided that comprises a resonator including a stem extending along an axis and a shell extending from the stem. The shell includes a hemispherical portion extending from the stem and a cylindrical portion extending from the hemispherical portion. The cylindrical portion includes an outer surface and an inner surface and terminates at an axial end surface that is perpendicular to the outer surface and the inner surface. The resonator further comprises an inner cylindrical substrate that extends along an axis and includes a set of inner electrodes arranged annularly about the axis, and a passage that extends along the axis through a central region of the inner cylindrical substrate. The stem extends through the passage to position the inner cylindrical substrate within the inner surface of the cylindrical portion of the resonator forming gaps between the set of inner electrodes and the inner surface.

摘要： One example includes a hemispherical resonator gyroscope (HRG). The HRG includes a sensing system comprising a plurality of electrodes arranged in a symmetrical annular arrangement about a sensitive axis and configured to electrostatically force a resonator into a substantially periodic motion based on a plurality of forcer signals applied to the plurality of electrodes. The plurality of electrodes are configured to provide an indication of rotation about a sensitive axis of the HRG. The HRG also includes a controller configured to generate the plurality of forcer signals in a phase-disparate manner to provide the substantially periodic motion in a vibration pattern such that a ratio of the plurality of electrodes and the vibration pattern is a non-integer number, and to measure the rotation about the sensitive axis of the HRG in response to the plurality of forcer signals.

摘要： One embodiment of the invention includes a CVG system. A plurality of electrodes electrostatically force a resonator into a periodic motion based on a drive axis forcer signal applied to a first set of the plurality of electrodes and a sense axis force-rebalance signal applied to a second set of the plurality of electrodes, and provides a sense axis pickoff signal and a drive axis pickoff signal. A gyroscope controller generates the drive axis forcer signal based on the drive axis pickoff signal and calculates an angular rate of rotation about an input axis based on the sense axis force-rebalance signal. The gyroscope controller modulates a predetermined disturbance signal component onto the sense axis force-rebalance signal and to control a modulation phase of the sense axis force-rebalance signal based on detection of the predetermined disturbance signal component in the sense axis force-rebalance signal to substantially mitigate bias and scale-factor error.

摘要： The invention relates to gyroscopic instruments. The method for calibrating the scale factor of an angular velocity sensor or an axisymmetric vibratory gyroscope, which method uses a control amplitude signal, a control precessional signal CP and a control quadrature signal CQ for exciting the vibration of a resonator on a resonant frequency, involves a first step of pre-calibration which consists of measuring and recording an initial scale factor and the value of an initial control signal, and a second step of measuring the value of the current control signal and establishing a scale factor SF that is corrected on the basis of a proportional relationship involving the initial scale factor SF°, the initial value of the control signal Y° and the current value of the control signal Y° according to the formula SF=SF°Y/Y°.

摘要： A method of controlling an inertial rotation sensor has a vibrating resonator having control channels and detection channels. During an operating stage each control channel (C1, C2) is activated for a control duration and each detection channel (D1, D2) is activated for a detection duration, in which the control and detection durations are applied at an operating ratio. Duyring a starting stage the control and detection durations are applied at a ratio that is modified in comparison with the operating ratio, so as to increase the control duration.
