摘　　要：介绍了一种能在静态下全天候、全方位、快速、实时的陀螺自动寻北仪,本寻北仪采用二位置寻北,二位置寻北方案结构简单、实现方便和精度高等优点得到广泛应用。寻北仪利用陀螺和加速度计分别测量地球自转角速度的分量及载体的倾角,寻北算法里包含了载体倾角补偿内容,不需将载体完全调平,在小倾角的条件下就能够自动寻北,最后通过数码显像管或串口通讯输出载体的某一固定轴与真北方向的夹角。The auto north seeker that is all-weather,omnidirectional,rapid and real-time seeker under static state is presented.This north seeker adopts a two-position determining scheme that is widely used thanks to it＇s simply construction,easy realization and high accuracy.This north seeker measures the component of self-rotation angle velocity of the Earth and inclination of carrier with gyro and accelerometer respectively.The north seeker can automatically worke in the case of small inclination without completely leveling the carrier due to the algorithm that includes the information about carrier inclination compensation.Finally,the angle between a fixed axis and truth north direction is output via digital kinescope or serial communication.
