On the Convergence of Iterative Orthogonalization Processes

Abstract: In many aerospace systems it is necessary to periodically transform vectors from a rotating Cartesian coordinate system to a reference Cartesian system. The transformation matrix is updated repeatedly through measurements and computations; however, since the corresponding computational algorithrn is not perfect, the resultant matrix is erroneous and quite often nonorthogonal. In order to correct the nonorthogonality error of the matrix, an orthogonalization process is used to obtain an estimate of the correct … Show more

“…This algorithm is suboptimal but is less computationally intensive than the OBF procedure, which involves the SVD ofD k=k . When applied recursively, this algorithm produces a sequence of estimates that converges to the optimal solution of (70) [19]. That technique was succesfully applied in a previous work on DCM identification [11].…”
