ABSTRACT:
A system which tracks and monitors a vehicle by utilizing cellular communication componentry and global positioning system componentry is disclosed. The system provides for simultaneous and continuous transmission of a voice signal and location data to a monitoring center. The monitoring center comprises componentry to communicate with the vehicle and determine the vehicle's location on a digitized map using a computer.
