Techniques for mitigating magnetic sensor errors are contemplated. In some aspects, the disclosed technology provides a method for reducing measurement errors in a directional module of a drilling system that includes steps for: receiving a current measurement from a current sensor, wherein the current measurement is associated with electrical current received at the current sensor via a first conductive branch and a second conductive branch, receiving a field measurement from a magnetic sensor, and associating the current measurement from the current sensor with the field measurement from the magnetic sensor. Systems and machine-readable media are also provided.
