| Abstract: |
| As the surrounding temperature has a great impact on the bias of MEMS (micro-electromechanical system) tuning fork gyro, which is commonly used in automobile and UAV navigation applications,the final performance of navigation can be directly affected by its bias stability which has much to do with temperature. To improve the bias of the gyro, the temperature drift characteristic at full temperature range is studied in this paper. The bias stability is improved by an order of magnitude through better design of the circuit and the real-time compensation algorithm |
