摘　　要：基于一种9加速度计配置方案,应用对数算法对无陀螺捷联惯导系统的角速度进行求解,对传统对数算法解算角速度进行了推导,详细分析了该方法解算角速度造成不能判断符号的原因,并针对此问题提出了积分法和一种准无陀螺方法来判断符号的解决方案.对传统对数算法和改进的对数算法解算角速度进行了仿真试验,验证了改进的对数算法可以判断解算角速度的符号.Based on a nine-accelerometer configuration, the logarithmic algorithm was applied to the angular velocity solver for gyroscope free strap-down inertial navigation system （GFSINS）. The angular velocity with the traditional method of logarithmic algorithm was deduced. The reasons why the method for solving angular velocity can not determine the symbol was analyzed. Against the problem of traditional logarithmic algorithm for solving angular velocity, the integration method and a nearly gyroscope free approach to judge the symbol were proposed. Simulation experiments for traditional method of logarithmic algorithm were simulated. Results show that the improved program can be judged the symbol of solving angular velocity
