inertial navigation

代码说明：

  利用STM32F103作为主控，陀螺仪作为惯性传感器，可导航小车在无GPS情况下走直线，误差照成由于没增加磁陀螺的原因无法校准航向角的累积误差，所以长时间运行会带来累积误差，如果有不需要磁陀螺就可以校准的方法欢迎大家给我留言提建议。(By using STM32F103 as main control, gyroscope as inertial sensors, navigation in the car without GPS. Straight line error according to cumulative error due to reasons not to increase the magnetic gyro calibration course angle, so long time operation will bring the cumulative error, if the method does not require calibration of the magnetic gyro can be welcome to give me message advice.)
