An electromagnetic tracking (EMT) system includes a tracked device, a tracking device, and a computing device. The EMT system is configured to receive, at the tracking device, an electromagnetic signal generated by the tracked device, determine, based on the electromagnetic signal, a set of possible positions and orientations of the tracked device relative to the tracking device, receive a measured inertial value representing a motion of the tracked device, determine an estimated inertial value corresponding to the motion of the tracked device based on at least one position and orientation of the set of possible positions and orientations, determine a difference value representing a difference between the estimated inertial value and the measured inertial value, determine a particular position and a particular orientation from the set in response to determining the difference value, and generate an output including the particular position and particular orientation.
