Abstract
A method for drilling includes rotating a BHA in a wellbore. Triaxial accelerometer and triaxial magnetometer measurements are made while rotating the BHA using corresponding triaxial accelerometer and triaxial magnetometer sets that are deployed in a roll-stabilized housing. Magnetic dip angles are computed from the accelerometer and magnetometer measurements using an inclination independent model. The computed dip angles are compared with a reference magnetic dip angle and a magnetometer bias is selected that minimizes a difference between the computed magnetic dip angles and the reference magnetic dip angle.
