title = "Research periodic error characteristics of quartz MEMS gyroscope in navigation system",
abstract = "The zero drift of quartz series MEMS gyroscopes has obviously periodic error items and the gyroscope output need data smooth process before navigate calculation in strap-down inertial navigation system. In this paper it is found that the frequency error of period item in zero drift is the main factor to influence the gyroscope precision by the analysis method of seeking every period parameter's error transfer coefficients with error analysis theories. The influence of the data smooth process upon the frequency characteristics of period item is described in mathematics form and the frequency transfer model is established, then the frequency transfer characteristics are analyzed. Experiment results are in accordance with, the theory analysis conclusion. The transfer coefficients characteristics are verified by compensation experiments and the frequency transfer model is verified by data smooth experiments. It is shown that the theory analysis conclusion can describe the periodic error exactly and this is benefit to improve gyroscope precision.",
