摘要

在九加速度计结构的基础上，详细分析了无陀螺仪捷联惯导系统的工作原理，给出了九加速度计结构下的角速度求解过程。构造了自适应卡尔曼滤波器的状态方程和滤波方程，并利用弹道数据，在外部噪声为白噪声的条件下，用高精度求解器对自适应卡尔曼滤波器进行了验证。

Application for solving angular velocity with adaptive kalman filtering in GFSINS

Based on a nine-accelerometer configuration, detailed analyzes the principle of gyroscope free strapdown inertial navigation system (GFSINS), and gives the process for solving angular velocity using a nine-accelerometer configuration. Adaptive kalman filter is constructed equation of state and filtering equations, and using a ballistic data, in the external noise is white noise conditions, and the adaptive kalman filter is verified with high precision solver.
