AB - The direct measurement of the Earth's rotation rate by means of a micromechanical yaw-rate gyroscope is difficult to achieve due to the considerable parameter variations of the current state-of-the-art sensors of this type. This paper outlines and applies a model of the external factors' effect on the sensor measurement via a method for their compensation through a mechanical change in the sensor's orientation. This allows the determination of a value such as the Earth's rotation rate, which is at the limit of the sensor's sensitivity and less than its short-term stability. A specialized information-measurement system has been developed for the implementation of the method. This system has been used for a number of measurements, presented in a graphical form. As a result, an average value of the Earth's rotation rate has been derived. This method is applicable for a subjective categorization and evaluation of micromechanical gyroscopes using a natural source of a very low angular speed.
