A Novel Self-Calibration Method and Experiment of MEMS Gyroscope Based on Virtual Coriolis Force

A New North-seeking Method Based on MEMS Gyroscope

In this paper, a new north-seeking method based on a low-cost Micro-Electro-Mechanical System (MEMS) gyroscope sensor has been proposed, which can solve the problem of long measurement time and low precision in north-seeking application. With this method the system has achieved an accuracy of approximately 2o with respect to the North orientation. In order to achieve this accuracy, firstly we c...

Design of a Novel MEMS Gyroscope Array

This paper reports a novel four degree-of-freedom (DOF) MEMS vibratory gyroscope. A MEMS gyroscope array is then presented using the novel gyroscope unit. In the design of the proposed 4-DOF MEMS vibratory gyroscope, the elements of the drive-mode are set inside the whole gyroscope architecture, and the elements of sense-mode are set around the drive-mode, which thus makes it possible to combin...

Non-axisymmetric Coriolis Vibratory Gyroscope with Whole Angle, Force Rebalance,

This paper presents detailed performance status and projections for the silicon MEMS Quadruple Mass Gyroscope (QMG) – a unique high Q, lumped mass, mode-symmetric Class II Coriolis Vibratory Gyroscope (CVG) with interchangeable whole angle, self-calibration, and force rebalance mechanizations. Analysis of a QMG sealed without getter with a Q-factor of 1e3 reveals an Angle Random Walk (ARW) of 0...

A Novel Non-driven Structural MEMS-based Gyroscope

This paper describes a unique capacitively-sensed MEMS-based gyroscope, which utilizes rotating carrier rotate as driven force and responds to an external angular rate of yaw due to the Coriolis Effect. The basic construction and operating principles of the gyroscope are described and illustrated. MEMS-based gyroscope output is presented at different yaw angular acceleration. The raw results ob...
