ABSTRACT:
The present invention relates to systems and methods to locate and recover objects equipped with tracking devices by determining the location information of the object. The system employs multiple radio direction finding (RDF) devices, which is capable of determining the angle of arrival of a radio signal. The MSC sends a request along with radio information to a location processor, which controls the RDF devices. The system also employs a theft detection device, which is capable of placing a wireless telephone call to a monitoring center. The theft detection device connects to and receives instructions from the monitoring center, which retrieves the instructions from a primary database server. If the primary database server is unavailable, the request for information is sent to a secondary database server.
