Method and system for providing tracking services to locate an asset
The present invention is directed to a method of asset location. Location data is received from a cellular transmitter associated with a selected asset, which location data includes data representative of a cellular receiver with which direct communication with the cellular transmitter is made. The location data is then communicated to a tracking service system, which tracking service system includes a database representative of geographic locations associated with a plurality of cellular receivers. The database is then queried with received location data so as to generate geographic tracking data associated with a location of the cellular receiver, the geographic tracking data including display data adapted to generate a map image including a representative of a location of the selected asset. The geographic tracking data is then communicated to an associated security agency so as to allow for viewing of an image generated in accordance with the display data and at least one of tracking and interception of the selected asset.
