Although the equations' derivation in our paper published in Sensors 2011 [1] is correct, a typo has been found in the summarizing Equations (48) and (49). The dot on the B in the skew matrix should be removed. Equations (48) and (49) should be corrected as:

δ B ˙ Q S F k + 1 b = [ 0 3 × 3 [ B Q S F k + 1 b × ] ] [ ɛ n δ b ω ] + [ 0 1 × 3 0 1 × 3 0 1 × 3 [ ω ^ B b × ] ] [ 0 3 × 1 η B ]
[ δ B Q S F k + 1 n δ B ˙ Q S F k + 1 b ] δ z = [ [ B Q S F k n × ] 0 3 × 3 0 3 × 3 [ B Q S F k + 1 b × ] ] H QSF [ ɛ n δ b ω ] δ x + [ C b n ω ^ B b ] η B
