| 摘 要： | 海洋传感器通常工作在复杂的磁场环境下，其姿态检测系统一般使用陀螺仪确定偏航角输出。针对短时部署的海洋传感器，分析了MEMS陀螺仪的偏航角漂移误差模型，并在对陀螺仪原始数据补偿的基础上，给出了随机漂移的拟合估值与补偿方法，以提高陀螺仪偏航角输出在一定时间内的精度。使用高精度平台进行实验，结果验证了该补偿校正方法的有效性。

| Abstract: | Marine sensors normally work in complex magnetic field environment, and its posture detection system usually use gyroscope to determine yaw angle output. Aiming at short-tetm deployment ocean sensor, analyze model of yaw angle drift error of MEMS gyroscope. On the basis of compensating original data of gyroscope, a method for fitting estimation value and compensation method of random drift is given to improve precision of yaw angle output of gyro in certain period of time. Use high precision platform for test and result verifies effectiveness of the compensation and calibration method. |
