Abstract
A method and apparatus for use in a security system for controlling access to mobile enclosures and cargo containers. Navigtational tracking systems such as LORAN and Global Positioning Systems are used to produce a real time geographic position signal. A programmable data processor is used to compare a preset geographic position signal to the real time geographic position signal. Upon favorable comparison of the real time and preset signals, an enabling signal is produced which permits operation of the security system to gain access to the container.
