This paper analyses the error sources of the quartz tuning fork gyroscope in theory. The physical model of error sources, including capacitance coupling, mechanical coupling and driving force coupling, are established. Furthermore, the expressions of these error sources are extracted. At last, the effects on the gyroscope of all the error sources are gotten throughout calculating an example, and it can be found that the results are according to the measurement value. So the coupling models of the quartz tuning fork gyroscope are reasonable.
