Abstract
A method for monitoring the location accuracy of an object tracking system includes receiving, from the object tracking system, a recorded position of a wireless test tag installed at a fixed position. This fixed position may be accurately determined without the tracking system, for example, using a laser measurement device. The method includes determining a positioning error of the tracking system by comparing the recorded position, as measured with the tracking system, to the fixed position. The method also includes outputting, in response to the positioning error exceeding a threshold, an indication that the tracking system has reduced accuracy. The method may be extended to several test tags located at several fixed positions throughout the operating area of the tracking system, in which case the indication of reduced accuracy may be generated when any one or more of the test tags has a positioning error exceeding the threshold.
