Security monitoring and tracking system
First Claim
1. A method of determining the latitude/longitude coordinate of a mode of transportation, including the steps of:
- providing a receiver on said mode of transportation for receiving pulses generated by a navigational tracking system having at least two transmitting stations;
receving the pulses generated by the navigational tracking system on said mode of transportation;
transmitting time-delay data based upon said pulses to a central station in communication with a fixed antenna from said mode of transportation; and
calculating the latitude/longitude coordinate of said mode of transportation at said central station based upon the time delay data received by said central station.

Abstract
A method and apparatus for positively indicating the position of a land-based vehicle, a marine vessel or an aircraft, utilizing a security system provided in the secured mode of transportation monitored by a central station. Navigational information transmitted by LORAN-C transmitters or satellite transmitters are received and then retransmitted to the central station which determines the exact latitude/longitude coordinates of the secured mode of transportation. The secured mode of transportation also includes a security panel for monitoring the condition of various parameters. An interface is connected to the security panel and the navigational receiver for coordinating the transmission of information relating to the conditions monitored by the security panel as well as the information received by the navigational receiver before they are sent to a radio for transmission to the central station.
