Abstract
A method to steer a drill bit of a rotary steerable system within a wellbore can include introducing the rotary steerable system into the wellbore. The method can further include establishing a magnetic model associated with the drill bit. Magnetic field parameters are measured at various locations of the rotary steerable system. A magnetic gradient tensor of the magnetic field parameters can be determined. Orientation parameters are solved with respect to the magnetic model and based on the magnetic gradient tensor. The drill bit can be steered based on the calculated parameters.
