The present invention relates to a location tracking system, and more particularly to a location tracking system that allows a tracking client to easily check the location of a tracking target using a GPS satellite.

Since GPS (Global Positioning System) satellites, which have been used for military purposes, have been made available for civilian use, application technology for location tracking using GPS satellites has been widely developed. In particular, GPS satellites are used to determine the location and speed of trains, aircraft, ships, and the like, and determine routes. The location tracking device using GPS satellites receives radio waves indicating latitude, longitude, altitude, speed, etc. from the GPS satellites and displays the current location of the object on a screen with map information.

The information transmission system using GPS satellites is largely a GPS satellite, a GPS satellite signal receiver for receiving GPS satellite signals, an arithmetic device for extracting location information from signals received from the GPS satellites, and an output device for displaying the calculated location information on the map information. In order to implement this visually, various hardware equipment or apparatuses are mobilized.

However, the location tracking system using GPS satellites has very high accuracy in the positioning of moving objects and tracking results, but has various defects in terms of tracking targets, utilization functions, auxiliary equipment, devices, and facilities. In other words, the location tracking service using GPS satellites is provided for location tracking information, public purpose, or commercial purposes according to the purpose of identifying the location and speed of the location tracking object or for military purposes in a car or an army. However, these service areas are used only in special fields that are far from the general public, and are rarely used in areas where location tracking is necessary in everyday life.

On the other hand, even if it is impossible to express itself or to some extent, it is more likely that the incapacitated person is lost or exposed to danger, and the development of a location tracking device for such a person is necessary. Such caregivers need to track their location because they are incapable of expressing their position as infants, infants, babies, infants, dementia patients, elderly patients, pets, lost items such as stolen vehicles or briefcases. However, the current location tracking system or service system using GPS satellites cannot provide the location information on the tracking object which is incapable of expressing the location by the self-will.

In addition, in the case of the location tracking system using the current GPS satellites, all the equipments and devices, such as the system of the terminal or the service center mounted or carried on the location tracking object, are all expensive equipment, and the general public does not have any economic burden, like household goods. It is impossible to equip and use.

On the other hand, in order to solve this problem, domestic utility model application No. 2000-17658 (portable GPS receiver with a built-in GPS receiver function, hereinafter referred to as 'prior application 1'), the short-range communication using GPS communication and RF to the object This GPS receiver can be mounted, and the GPS receiver transmits the position of the object to a remote service center. In addition, the service center provides the location of the object through the web, so that the client can access the Internet to determine the location of the object.

Although the preceding application 1 is meaningful in that the portable terminal is light and easy to carry, the client cannot determine the location of the object in real time without accessing the object in real time. Therefore, the process of identifying the location of the object is not only cumbersome, but also takes time to locate the object, which causes a problem that the object may move out of the client's range while the client is connected to the Internet.

As another prior application, Korean Utility Model Application No. 2003-18153 (Infant or pseudo-incompetent location tracking system or service using GPS technology and a mobile communication terminal, hereinafter referred to as 'Previous Application 2'), provides information on location information from GPS satellites. A GPS receiver capable of reception is provided in a set with a mobile communication device, and the GPS receiver transmits location information to a service center of the mobile communication device. When the mobile communication device provided with the set is connected to the wireless Internet, the service center is to provide the location information of the GPS receiver.

Although the preceding application 2 has an advantage that the accessibility of the information is easier than the previous application 1 in that it can be connected to the wireless Internet using a mobile communication device to determine the location of the GPS receiver, the requester is still a mobile communication device. It is disadvantageous in that collection of real-time location information is not smooth in that the location of the GPS receiver can be determined only by arbitrarily accessing the wireless Internet by using.

In addition, vehicle navigation, which is widely used in recent years, displays a vehicle's position, speed, and movement path by using a GPS satellite, using a display device, which is attached to a vehicle, that is, a limited use. There is a problem that must be used only.

The present invention has been made to solve the problems described above, by using a mobile communication terminal and a GPS receiver provided in a set not only can grasp the position information of the GPS receiver in the mobile communication terminal in real time, but also for vehicles and portable Its purpose is to provide a location tracking system that can also be used for navigation.
