1. A computer-implemented method comprising:
receiving a first orientation signal, wherein the first orientation signal comprises a magnetic field signal generated from measurements produced by a magnetometer disposed in a drilling tool chassis;
receiving a second orientation signal;
processing the magnetic field signal to generate a clean magnetic field signal; and
calculating a residual signal based on the clean magnetic field signal and the second orientation signal.
