Methods for Improving the Accuracy of an Autonomous Orientation and Navigation System Based on Micromechanical Gyroscopes and Optoelectronic Sensors

In this work, we investigate methods for improving the accuracy of the orientation and navigation system of a highly maneuverable object. The object is based on an integrating micromechanical gyroscope and optoelectronic sensors for monitoring the environment. We have studied the influence of nonlinear effects in the dynamics of a micromechanical gyroscope. These effects are due to the low nonlinearity of the oscillatory circuit. We have obtained expressions for the drift of a micromechanical gyroscope. The reason for this drift is the nonlinear viscoelastic properties of the resonator material. In this paper, we have proposed methods and algorithms for improving the accuracy of the orientation and navigation system.
