Abstract
Automatic synchronization of a magnetic field transmitter and receiver is performed to resolve phase ambiguity so that phase information, used in determining the position and orientation of the receiver, may be derived and maintained. Inertial measurement unit (IMU) information is used to infer gravity-relative orientations of the transmitter and receiver, which are then used as constraints in the synchronization process to determine the position and orientation of the receiver from all four possible solutions or variations. The variation that best conforms to the IMU orientations is chosen as the sync candidate.
