Abstract : The report distinguishes two distinct errors which arise due to the non-commutativity of rotations in strapdown inertial guidance applications. The errors affect the updating of the direction cosine matrix which is the solution of the matrix differential equation dC/dt = C(omega). A method to reduce each error is discussed. (Author)
