WebAug 6, 2015 · The Wahba's problem is widely recognised as a least-square problem in three-axis attitude estimation from vector measurements. However, both the observation and the reference vectors can be corrupted by errors, so a total least-square problem considering both errors should be formulated to be rigorous.
