Abstract

A real-time location and tracking system includes location markers programmed with location information of the locations that the location markers are affixed to and a mobile RTLS tracking system to read location information from nearby location markers and a mobile RTLS monitoring and display system. The system is configured to receive signals from the mobile RTLS tracking system that includes a microprocessor and memory that control the functionality of the mobile RTLS monitoring and display system to display status and geo coordinates of the mobile RTLS tracking system.

Claims

1. A real-time location system comprises:

a plurality of location markers programmed with location information of the locations that the location markers are affixed to around a site;

a mobile tracking system to read location information from nearby location markers that are placed around the site;

a mobile monitoring and display system, the system configured to receive signals from the mobile tracking system; and

comprising;

a microprocessor and memory which control the functionality of the system to display status and geo coordinates of the mobile tracking system.

2. The real-time location system of claim 1 further comprising:

a positioning transceiver system, configured to determine the position of the positioning transceiver system relative to a global coordinate system during set up.

3. The real-time location system of claim 1 further comprising:

4. The real-time location system of claim 1 wherein the location markers are read by the mobile tracking system, and the mobile tracking system produces for a location marker, a record of the time that the location marker was read and the geo coordinate information and/or the user-friendly location name on the location marker.

5. The real-time location system of claim 1 wherein the positioning transceiver system elements are placed throughout the site.

6. The real-time location system of claim 1 wherein the location information is geo coordinate information and/or user-friendly location information.

7. The real-time location system of claim 1 wherein the location markers comprises:

circuitry including a processor and memory that controls location marker and is configured to be programmed with geo coordinates and/or the friendly location information, and an antenna for the communication of location information.

8. The real-time location system of claim 1 wherein the mobile tracking system further comprises:
