Wahba's problem has been effectively solved via quaternion estimator (QUEST, [20]), fast optimal attitude matrix (FOAM, [21]), the estimator of quaternion (ESOQ, [22]), singular value decomposition (SVD, [23]), Riemannian-manifold method [24], our recent fast linear attitude estimator (FLAE, [25]), and so on.
The covariance of the attitude quaternion can be given by the results from QUEST, ESOQ, and so on, except that it should be prior multiplied by the conversion matrix to ensure correct correspondence for a scalar-wise quaternion.
