    摘要: An accelerometer system includes a rigid plate system coupled to an inertial platform. A first flexure plate defines a first flex axis and is adjacent to the rigid plate system a first distance from the spin axis. The first flexure plate generates a first frequency signal in response to acceleration of the first flexure plate. A second flexure plate defines a second flex axis and is adjacent to the rigid plate system a second distance from the spin axis. The second flexure plate generates a second frequency signal in response to acceleration of the second flexure plate. A controller including receives the first frequency signal and the second frequency signal and generates an angular acceleration signal from a difference of the first frequency signal and the second frequency signal. The controller also generates a linear acceleration signal in response to an average of the first frequency signal and the second frequency signal. The controller also controls a missile system in response to the first frequency signal and the second frequency signal.

    摘要: A leveling system for a missile system includes a platform defining an xz-plane and a yz-plane. A first dual bridge sensor is coupled to the platform at an angle such that the first dual bridge sensor is sensitive to movement of the first dual bridge sensor in the xy-plane. The first dual bridge sensor includes a first flexure plate generating a first dual bridge sensor signal in response to movement of the first flexure plate. A second dual bridge sensor is coupled to the platform at an angle such that the second dual bridge sensor is sensitive to movement of the second dual bridge sensor in the xy-plane. The second dual bridge sensor includes a second flexure plate generating a second dual bridge sensor signal in response to movement of the second flexure plate. Third and fourth dual bridge sensors are arranged similarly to the first and second dual bridge sensors but with respect to the yz-plane. A processor drives the sensors with a precision sine wave and rotates the platform in response to the sensor signals.

    摘要: A compass system includes a platform defining an x-axis, a y-axis and an xy-plane, wherein a z-axis is orthogonal to the xz-plane. A beam is rotatably coupled to the platform such that the beam rotates about the y-axis. An accelerometer including a flexure plate perpendicular to the y-axis is coupled to the beam a distance from the y-axis. The accelerometer generates an accelerometer signal in response to movement of the flexure plate. An angular position sensor senses angular position of the beam relative to the x-axis and y-axis, the angular position sensor generating an angular position signal therefrom. A processor receives the accelerometer signal and the angular position signal and generates an East-West signal therefrom.

    摘要: A capacitance accelerometer includes a housing, and a plate fixed within the housing. A moveable plate is disposed in substantially parallel relation to the fixed plate and is coupled to the housing along at least an edge. The moveable plate and the fixed plate define a distance. The distance varies in response to acceleration forces acting upon the moveable plate, and wherein the moveable plate and the fixed plate generate a charge displacement capacitance signal. A transimpedance amplifier receives the charge displacement capacitance signal and generates a scaled voltage signal therefrom. An acceleration signal is generated from the scaled voltage signal.

    摘要: A capacitance acceleration derivative detector includes a housing, and a first plate fixed within the housing. A second plate is also fixed within the housing and spaced apart from and in parallel relation to the first plate. A flexure plate is disposed between and in substantially parallel relation to the first and second plates. The flexure plate is coupled to the housing along at least an edge. The flexure plate and first plate define a first distance and the flexure plate and the second plate define a second distance. The first and second distances vary in response to acceleration forces acting upon the flexure plate. The flexure plate and the first fixed plate generate a first charge displacement capacitance signal, and the second fixed plate and the flexure plate generate a second charge displacement capacitance signal. A first transimpedance amplifier receives the first charge displacement capacitance signal and generates a first scaled voltage signal therefrom, and a second transimpedance amplifier receives the second charge displacement capacitance signal and generates a second scaled voltage signal therefrom. An acceleration signal is generated from the first scaled voltage signal and the second scaled voltage signal.
