Abstract
A vehicle alarm system includes a receiver transmitter subsystem, a G.P.S. subsystem for locating a position and a control CPU. The CPU performs a log and locate function in which it logs a first position of the vehicle once during an armed state of an alarm system and then, in response to the passage of a certain time interval, locates the position again. If the position of the vehicle has changed during the alarm of the alarm system, the vehicle's position is transmitted via the receiver/transmitter subsystem to a security response center that can then receive tracking information and locate the vehicle.
