Abstract
In some aspects, the disclosed technology provides solutions for computing a residual noise signal from received gravitational field signal data. In one aspect, a process of the disclosed technology includes steps for receiving a magnetic field signal, wherein the magnetic field signal is generated by measurements produced by a magnetometer disposed in a drilling tool chassis, receiving a gravitational field signal, and processing the magnetic field signal to generate a clean magnetic field signal. In some aspects, the process can further include steps for calculating a residual signal based on the clean magnetic field signal and the gravitational field signal. Systems and machine-readable media are also provided.
