Abstract
A low-power object tracking system is disclosed that includes an object tracking device that senses one or more magnetic field(s) to determine a position of the object tracking device. The object tracking device includes a magnetic field sensor including one or more receiving coils and position tracking circuitry in communication with the magnetic field sensor. The position tracking circuitry is configured to determine at least one field strength associated with at least one stationary magnetic field sensed at the one or more receiving coils, and to determine position information associated with the housing based at least in part on the at least one field strength. The object tracking device includes a communication interface configured to transmit the position information to at least one remote computing device.
