LOW ACCURACY POSITIONAL DATA BY DETECTING IMPROBABLE SAMPLES

摘要

An embodiment of the invention provides a method of determining a location of a mobile target that processes locations for the target provided by a wireless location technology tracker system to determine moving averages of velocity of the target, determines if the locations are outliers responsive to the moving averages, discards locations that are determined to be outliers, and uses locations determined not to be outliers as locations for the target.

主权项

1. Apparatus for determining a location of a mobile target, the apparatus comprising:
a wireless location technology (WILOT) tracker that provides locations of the target; and a processor that:
generates moving averages for a velocity that characterizes motion of the moving target responsive to the locations;uses the moving averages to determine whether or not a given location provided by the WILOT tracker is an outlier; anduses the given location as a location for the target if it is determined not to be an outlier.
