Abstract :
The author investigates in detail the linear transformation required to obtain orthogonal components of a vector given the nonorthogonal components of that vector, as produced by a physical sensor triad in an inertial measurement unit. The orthogonalization transformation is derived in general terms and then specialized to the usual case of small-angle misalignments. The small-angle version of the orthogonalization matrix verifies the result of a brief treatment by K.R. Britting (1971)
