Using GY 85 and TinyEKF for pose estimation
The information about the 9DOF sensor is on https://github.com/madc/GY-85. Thanks a lot to the author.
#EKF I learn about EKF on http://home.wlu.edu/~levys/kalman_tutorial , and TinyEKF is on https://github.com/simondlevy/TinyEKF. Thanks a lot to the author.
#Compensate magnetometer tilt I use the gravity vector to compensate the tilt of the magnetometer, it works fine.
