Earth Rotation Measurement Using a Fiber Optic Gyroscope and Digital Minimization of Measurement Error

Popis výsledku v původním jazyce

The purpose of this paper is to verify the possibility of measuring the angular velocity of rotation of Earth using a fiber optic gyroscope, whose measurement error is higher than the value of the measured angular velocity. This is not possible in a conventional way because the measured signal is below the noise level. The paper deals with the description of the function of the proposed error calibration method for a fiber optic gyroscope that can be used for measuring very slow angular velocities. The measurement of the angular velocity of the Earth's rotation was chosen as a model task for the verification of the newly designed calibration procedure. The proposed method calibrates the DC component of the cumulative error effectively as well as the slow changing and fast changing AC component of the error. However, the proposed method cannot eliminate the systematic error that occurs during the measurement and which was not taken into account at the beginning. The calibration method makes possible to measure the angular velocity of the Earth’s rotation by means of a fiber optic gyroscope sensor, the measurement error of which is greater than the value of the angular velocity of the Earth's rotation.
