The gyroscope free strap-down INS is composed only of accelerometers. Any gyroscope free INS navigation error is deeply affected by the accuracy of the sensor bias, scale factor, orientation and location error. However these parameters can be found by calibration. There is an important research issue about a multi-position calibration method in this paper. It provides a novel method to find the...
In this work, the mechanical design and the experimental validation of a microelectromechanical frequency-modulated (FM) pitch gyroscope are presented. The proposed device is fabricated through the ThELMA © surface micromachining process of STMicroelectronics and it represents, to the authors’ knowledge, the first small-footprint (690 μm × 946 μm) prototype of FM gyroscope able to measure an in...
In this paper, the adverse effects of variation in operating temperature, on the performance of PM sensors and actuators used in aerospace and military applications, and methods to provide inherent temperature compensation by design, are presented. Unlike the conventional shunt compensation, the proposed method uses the direct leakage path between two neighboring permanent magnets. This novel m...
A new digitized decoupled dual-axis micro dynamically tuned gyroscope with three equilibrium rings (TMDTG) is proposed which can eliminate the constant torque disturbance (CTD) caused by the double rotation frequency of a driving shaft with a micro dynamically tuned gyroscope with one equilibrium ring (MDTG). A mechanical and kinematic model of the TMDTG is theoretically analyzed and the struct...
An open-loop, all-fiber-optic gyroscope with wide dynamic range and linear scale factor is described. This novel approach converts the Sagnac phase shift into a phase shift in a low-frequency electronic signal by using optical phase modulation followed by amplitude modulation verify the theoretical predictions.
A new approach to closed-loop operation of an all-fiber-optic gyroscope using phase modulation and signal gating is described. This approach provides simplicity of implementation and the capability of wide dynamic range with an approximately linear scale factor. Experimental results are compared with theoretical calculations.
A new approach to an open-loop, all-fiber gyroscope with a wide dynamic range and a linear scale factor is described. For signal processing, the Sagnac phase shift is converted into a phase shift in the low-frequency electrical signal by using a triangular phase-modulation waveform followed by gate switching. The basic principle of this technique and experimental results are reported.
