Now the question is is it possible to find the coordinates of a and m with respect to the fixed world basis w_1 w_2 w_3 where w_1 points toward East w_2 points toward magnetic North and w_3 points up toward the sky The answer is yes provided.. m with respect to the fixed world basis w_1 w_2 w_3 where w_1 points toward East w_2 points toward magnetic North and w_3 points up toward the sky The answer is yes provided 2 important assumptions are satisfied. With these 2 assumptions it is.. simple to calculate just a few cross products the change of basis matrix R from the basis x y z to the basis w_1 w_2 w_3 which in Android is called the Rotation matrix . Then the coordinates of a vector v with respect to the basis w_1 w_2 w_3..
