Patent No. 5905461 Global positioning satellite tracking device
Patent No. 5905461
Global positioning satellite tracking device (Neher, May 18, 1999)
Abstract
A global positioning and tracking system for locating one of a person and item of property. The global positioning and tracking system comprises at least one tracking device for connection to the one of the person and item of property including a processing device for determining a location of the tracking device and generating a position signal and a transmitter for transmitting said position signal. The position signal is transmitted to a relay station strategically positioned about a desired monitoring area. The relay station includes a device for receiving the positional signal and determining if the received position signal is a valid signal and a device for relaying the position signal upon determining the position signal is valid to a central monitoring station. The central monitoring station receives the validated positional signal from the relay station and analyzes the position signal for monitoring the position of the tracking device. The system may also include a tracking satellite for receiving the validated position signal from the relay station and re-transmitting the position signal to the central monitoring station when the central monitoring station is located outside the transmission range of the relay station.

SUMMARY
OF THE PRESENT INVENTION
The present invention relates generally to tracking systems and, more specifically,
to a global positioning tracking system for locating the position of a person
or item anywhere at anytime.
A primary object of the present invention is to provide a global positioning
and tracking system that will overcome the shortcomings of prior art devices.
Another object of the present invention is to provide a global positioning and
tracking system which is able to locate individuals and personal property anywhere
around the world.
An additional object of the present invention is to provide a global positioning
and tracking system including a transmitter/receiver for attachment around an
individuals wrist or ankle or to an item of personal property.
A still further object of the present invention is to provide a global positioning
and tracking system that is operable in both a normal and standby mode.
An even further object of the present invention is to provide a global positioning
and tracking system including a remote transmitter/receiver within a band made
of an uncuttable material.
A still further object of the present invention is to provide a global positioning
and tracking system including a band having an identification code unique to
the particular band.
A yet further object of the present invention is to provide a global positioning
and tracking system including an emergency activation button for alerting a
main station as to the existence of an location of an emergency situation.
Another object of the present invention is to provide a global positioning and
tracking system that is simple and easy to use.
A still further object of the present invention is to provide a global positioning
and tracking system that is economical in cost to manufacture.
Additional objects of the present invention will appear as the description proceeds.
A global positioning and tracking system for locating one of a person and item
of property is described by the present invention. The global positioning and
tracking system comprises at least one tracking device for connection to the
one of the person and item of property including a processing device for determining
a location of the tracking device and generating a position signal and a transmitter
for transmitting said position signal. The position signal is transmitted to
a relay station strategically positioned about a desired monitoring area. The
relay station includes a device for receiving the positional signal and determining
if the received position signal is a valid signal and a device for relaying
the position signal upon determining the position signal is valid to a central
monitoring station. The central monitoring station receives the validated positional
signal from the relay station and analyzes the position signal for monitoring
the position of the tracking device. The system may also include a tracking
satellite for receiving the validated position signal from the relay station
and re-transmitting the position signal to the central monitoring station when
the central monitoring station is located outside the transmission range of
the relay station.
To the accomplishment of the above and
related objects, this invention may be embodied in the form illustrated in the
accompanying drawings, attention being called to the fact, however, that the
drawings are illustrative only, and that changes may be made in the specific
construction illustrated and described within the scope of the appended claims.
