本文基于四元素利用mahony互补滤波然后通过粒子滤波来实现姿态解算(Attitude calculation based on four elements)

AHRS中姿态解算算法的实现，包括Mahony和Madgwick的算法(AHRS in the realization of the posture algorithm, including Mahony and Madgwick algorithm)

JY901运动模块9轴（加速度计，陀螺仪以及磁位计）姿态角解算(9 axis attitude angle calculation of JY901 motion module)

姿态解算融合，是Crazepony和核心算法 使用的是Mahony互补滤波算法，没有使用Kalman滤波算法(The fusion of attitude calculation is Crazepony and the core algorithm The Mahony complementary filtering algorithm is used, and the Kalman filtering algorithm is not used)
