Tracking system and method
First Claim
1. A system for determining and communicating the position of an entity, comprising:
- a wireless communication unit;
a navigation receiver unit; and
a processing unit coupled to said wireless communication unit and said navigation receiver unit, said processing unit operable to;
receive position data for said entity from said navigation receiver unit;
receive a position request from said wireless communication unit;
responsive to the position request, send an authentication request to said wireless communication unit;
receive a reply from said wireless communication unit, the reply including an authentication code;
compare the authentication code with a predetermined code;
determine if the authentication code is substantially equal to the predetermined code; and
if the authentication code is substantially equal to the predetermined code, send said position data for said entity to said wireless communication unit for transmission responsive to said position request.

Abstract
A system and method for determining and communicating the precise location of an individual and/or a motor vehicle in real-time is disclosed. As an example, a tracking system is disclosed that includes a Global Positioning System (GPS) receiver, a cellular phone, and a processing unit. The GPS receiver, cellular phone and processing unit are arranged as a single, compact tracking unit. The processing unit receives precise location information (e.g., latitudinal and longitudinal coordinates) for the tracking unit from the GPS receiver. A cellular phone capable of receiving text messages (e.g., and/or voice messages) can be used to call the cellular phone of the tracking unit, which responds (e.g., to an authenticated call) by transmitting a text message (e.g., or synthesized voice message) including the precise coordinates of the tracking unit. Thus, either with or without the knowledge of the individual carrying the tracking unit or driving the motor vehicle containing the tracking unit, the system is capable of providing the exact location of the individual and/or motor vehicle to another at any point in time.

16. A tracking system, comprising:
-
means for receiving and transmitting at least one message associated with a position of said system;
means for determining said position of said system; and
means for receiving position data for said system, receiving a request message for said position data, sending an authentication request, receiving a reply including an authentication code, comparing the authentication code with a predetermined code, determining if the authentication code is substantially equal to the predetermined code, and transmitting said at least one message responsive to said request, if the authentication code is substantially equal to the predetermined code. - View Dependent Claims (17, 18, 19)

20. A method for determining and communicating the position of an entity, comprising the steps of:
-
receiving position data for said entity from a navigation receiver unit;
receiving a position request from a wireless communication unit;
responsive to the position request, sending an authentication request to the wireless communication unit;
receiving a reply from the wireless communication unit, the reply including an authentication code;
comparing the authentication code with a predetermined code;
determining if the authentication code is substantially equal to the predetermined code;
sending said position data for said entity to said wireless communication unit if the authentication code is substantially equal to the predetermined code; and
said wireless communication unit transmitting said position data responsive to said position request if the authentication code is substantially equal to the predetermined code. - View Dependent Claims (21, 22)

23. A computer program product, comprising:
-
a computer-usable medium having computer-readable code embodied therein for configuring a computer processor, the computer program product comprising;
a first executable computer-readable code configured to cause a computer processor to receive position data for an entity from a navigation receiver unit;
a second executable computer-readable code configured to cause a computer processor to receive a position request from a wireless communication unit;
a third executable computer-readable code configured to cause a computer processor to send an authentication request to the wireless communication unit;
a fourth executable computer-readable code configured to cause a computer processor to receive a reply from the wireless communication unit, the reply including an authentication code;
a fifth executable computer-readable code configured to cause a computer processor to compare the authentication code to a predetermined code;
a sixth executable computer-readable code configured to cause a computer processor to determine if the authentication code is substantially equal to the predetermined code;
a seventh executable computer-readable code configured to cause a computer processor to send said position data for said entity to said wireless communication unit if the authentication code is substantially equal to the predetermined code; and
an eighth executable computer-readable code configured to cause a computer processor to enable said wireless communication unit to transmit said position data responsive to said position request if the authentication code is substantially equal to the predetermined code. - View Dependent Claims (24)
