Abstract
The TWOSTEP algorithm, which has been applied successfully to the attitude independent estimation of magnetometer biases is extended to estimate scale factors and nonorthogonality corrections. For the case of a spinning spacecraft, the algorithm performs well. This goes against the common wisdom that not much more than biases can be determined without knowledge of the attitude.
