#$%^&*AU2016219564B220171221.pdf#####Abstract An apparatus for mapping and accuracy-testing an electromagnetic navigation system includes a sensor (134) sensing electromagnetic vectors of an electromagnetic field, a carriage (120) moving the sensor (134) along a first direction and a second direction different from the first direction, a first position detector operatively associated with the sensor (134) and detecting a first position of the sensor (134) along the first direction, a second position detector operatively associated with the sensor (134) and detecting a second position of the sensor (134) along the second direction, and a controller (140) operatively associated with the sensor (134) and controlling movements of the carriage (120) along the first and second directions and mapping the electromagnetic field based on the sensed electromagnetic vectors at predetermined positions in a coordinate system defined by the first direction, the second direction, and a third direction perpendicular to a plane defined by the first and second directions.
