Abstract
A method of receiving EM field magnitude values indicative of a first pose of a mobile unit in relation to a base unit, receiving sensor data from a second sensor associated with the mobile unit, where the sensor data is indicative of a direction of movement of the mobile unit, calculating a set of candidate pose solutions based on the EM field magnitude values, selecting a pose from the set of candidate pose solutions based on the sensor data from the second sensor, and sending the pose to the processor.
