This paper presents a novel parasitic-insensitive switched-capacitor (PISC) sensing circuit design in order to obtain high sensitivity and ultra linearity and reduce the parasitic effect for the out-of-plane single-gimbaled decoupled CMOS-MEMS gyroscope (SGDG). According to the simulation results, the proposed PISC circuit has better sensitivity and high linearity in a wide dynamic range. Exper...

Abstract. This paper describes a new technique for the demodulation of Sagnac fiber optic gyroscopes, based on the zero-crossing technique. The technique uses a digital approach with a quasi-synchronous clock, which allows for the implementation of very high resolution and low cost gyroscope demodulation circuits. The proposed demodulation circuit was tested in laboratory, using a emulated gyro...

An innovative implementation of attitude estimation in 3 degrees of freedom (3-DOF) combining the TRIAD algorithm [1] and a time-varying nonlinear complementary filter (TVCF) is derived. This work is inspired by the good performance of the TVCF in 1-DOF [2] developed for applications limited to small mobile platforms with low computational power. To demonstrate robust 3-DOF estimation, informat...

This paper presents an efficient servomotor-aided calibration method for the triaxial gyroscope. The entire process only requires approximately one minute, and does not require high-precision equipment. is based on idea that measurement of gyroscope should be equal to rotation speed servomotor. A six-observation experimental design proposed minimize maximum variance estimated scale factors bias...

The combination of micro-machined technology with the Atomic Spin Gyroscope(ASG) devices could fabricated Chip Scale Gyroscope(CASG). core gyroscope is a vapor cell which contains alkali metal and isotope enriched noble gases such as 129Xe 131Xe. quadrupolar frequency shift 131Xe key parameters affect drift ASG related to material in they are contained. In micro machined technology, typical uti...

The temperature-dependent exchange rate and signal coalescence in the 13C CPMAS NMR spectrum of a crystalline molecular gyroscope are exposed by specifically deuterating the overlapping static carbons.
