Abstract: An Internet based personal tracking system for tracking the position of a portable location unit by a remote user comprising a web host connected to the Internet having a computer storage medium, a portable location unit having a processor for receiving geo-position information, and generating geo-position data representing the position of said location unit, a transceiver included in said location unit for transmitting said position signal to said web host in response to a call signal being received from said web host, a power supply for supplying power to said processor and said transceiver; and a computer program residing on said web host having an input module for receiving a tracking request signal from the remote user via the Internet, a processing module for processing said tracking request signal, and a communication module for initializing communication with said location unit in response to tracking said request signal, and a location module for outputting said call signal to said location unit and

Abstract: A system for tracking a person from a system subscriber who affixes a location unit to the person to be tracked is provided wherein the location unit calculates the location of the person at any given time. The system includes a web host connected to a wide area web network, such as the Internet, the web host includes a computer readable medium and is accessible by the subscriber from a remote computer terminal. A computer program resides on the web host for receiving a tracking request from the subscriber and transmitting a tracking call to the location unit carried by the person. The computer program includes instructions embodied in computer readable code for automatically transmitting the tracking call, receiving location data from the location unit in response to the tracking call, and transmitting the location data to the subscriber's terminal where the current location of the person is displayed.

Abstract: A computerized system deters theft of a vehicle where a subscriber maintains a remote computer terminal. A web host is connected to a wide area web network and includes a computer readable medium. A location unit is carried by the vehicle and calculates the location of the vehicle at any given time and transmits a low power digital location data packet having location data. A computer program has instructions embodied in computer readable code on the web host and receives a tracking request from a subscriber and transmits a tracking call to the location unit. The low power digital location data packet is transmitted from the location unit and represents the current position of the vehicle.
