27. A method for tracking a device, the method comprising the steps of:
-
receiving data including Global Positioning System (GPS) information corresponding to tracking of the device coupled to a vehicle; and
filtering the data to account for GPS signal errors according to one of a minimum movement filter, an excessive speed filter or an erroneous position filter, wherein the minimum movement filter yields non-movement of the vehicle based on a predetermined radial distance threshold, wherein the excessive speed filter invalidates speed of the vehicle based on the number of GPS satellites used to determine the speed, wherein the erroneous position filter invalidates position of the vehicle based on a determined distance traveled over time interval or the number of GPS satellites.
