Hello I was wondering if you could go over the gravity, accelerometer, magnetometer equtions. Maybe use an example on how the calculations would go about.

Extracted text: Gravity equation Rotation ay = Matrix R [az. 1 ax cos(pitch) 0 -sin(pitch) 1 cos(roll) sin(roll) ay cos(pitch) 0 -sin(roll) cos(roll) az sin(pitch) ||


Extracted text: Magnetometer equation Rotation my = Matrix R [mz. cos(pitch) 0 -sin(pitch)| cos(yaw) -sin(yaw) 0 sin(yaw) mx my 1 cos(roll) sin(roll) cos(yaw) M mz sin(pitch) 0 cos(pitch) 0 -sin(roll) cos(roll) 1 Pitch, roll known from accelerometer Unknown yaw can be determined from above equations yaw, pitch, roll together determine the rotation matrix (3D orientation) of a system
