Abstract

A system for locating a vehicle using the Global Positioning Satellite System (GPS).
The system includes a locator unit and a remote unit. The locator unit is connected to the vehicle and includes a processor; a transmitter for obtaining a location from the GPS
indicating the location of the vehicle; and a receiver for receiving the location signal from the GPS for storage in the processor. The remote unit includes a processor; a transmitter for obtaining a location from the GPS indicating the location of the remote unit; and a receiver for receiving the position signal from the GPS for storage in the processor. A
device, connected to the processor, generates a request signal requesting the location of the locator unit; and a signal device relays a relative position of the locator unit to a user. Upon activation of the generating device the transmitter transmits the request signal to the locator unit. The locator unit retrieves and transmits the location signal to the remote unit in response thereto. Upon receipt of the location signal the processor of the remote unit compares the location signal to the position signal to determine a relative position of the locator unit with respect to the remote unit. The processor then controls the signal device to indicate the relative position of the locator unit. The signal device provides both an audible and visual indication to the user as to the longitude, latitude and altitude of the locator unit.
