The Global Positioning System is constituted by a plurality of space satellites, ground control stations and GPS receivers. There are 20 currently 24 space satellites surrounding earth, and each space satellite 2 continuously transmits a satellite geographic coordinate signal carrying satellite orbit information and time, to provide to all kinds of the GPS receivers on earth. On the other hand, the ground control stations are responsible for tracking and controlling an operation of each space 5 satellite, as well as for correcting and maintain each space satellite, such that the space satellites can normally and continuously transmit parameters and information to the GPS receivers. However, an ordinary conventional satellite navigation machine can only mark an existing location, and indicate a traveling route and 10 buildings nearby that route; the satellite navigation machine has not yet been used to track a location of a pet (e.g., a dog), which results in that the pet will be very difficult to be found after missing. Accordingly, a range of application is limited and therefore, designs are required to satisfy demands of other range of application. 15 For the purposes of this specification the word "comprising" means "including but not limited to", and the word "comprises" has a corresponding meaning. Also a reference within this specification to a document is not to be taken as an admission that the disclosure therein constitutes common general knowledge in Australia. 3 SUMMARY OF THE INVENTION The primary object of the present invention is to provide a pet tracking system utilizing the GPS, which can receive a satellite geographic coordinate signal to acquire a location of a pet and transmit 5 this location to a remote server for tracking that pet. Accordingly, the pet tracking system using the GPS, in accordance with the present invention, includes a GPS tracker which is provided in a pet collar. The GPS tracker is provided with a GPS receiving circuit, a microprocessor, a wireless transmission circuit and a rechargeable 10 battery, wherein the rechargeable battery provides electricity to the GPS tracker, the GPS receiving circuit receives a satellite geographic coordinate signal to acquire a location of a pet (e.g., a dog) by mapping the satellite geographic coordinate signal to a pre-stored geographic data base, and transmits this location to the microprocessor. Upon 15 using the pet GPS tracking system, the microprocessor can acquire the location of the pet from the GPS receiving circuit, and transmit that information to a remote server through the wireless transmission circuit for querying. Thus, the location of that pet can be tracked by the remote server, thereby avoiding that the pet is very difficult to be found 20 after missing. 4 To enable a further understanding of the said objectives and the technological methods of the invention herein, the brief description of the drawings below is followed by the detailed description of the preferred embodiments. 5 BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a three-dimensional view of a pet tracking system using the GPS, in accordance with the present invention. FIG. 2 shows an exploded view of a pet tracking system utilizing the GPS, in accordance with the present invention. 10 FIG. 3 shows a circuit diagram of a pet tracking system utilizing the GPS, in accordance with the present invention. FIG. 4 shows a schematic view of a pet tracking system utilizing the GPS, in accordance with the present invention, which is being used. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 15 Referring to FIGS. 1 to 4, a pet tracking system utilizing the GPS, in accordance with the present invention, comprises a GPS tracker 20 which is provided in a pet collar 10 (such as a dog collar, a horse collar, a lamb collar, or a pig collar, etc.). The GPS tracker 20 is provided with a GPS receiving circuit 21, a microprocessor 22, a wireless transmission 20 circuit 23 and a rechargeable battery 24, wherein the rechargeable 5 battery 24 is connected with the microprocessor 22 and provides electricity to the GPS tracker 20. The GPS receiving circuit 21 is connected with the microprocessor 22 and can receive a satellite geographic coordinate signal, followed by 5 mapping the satellite geographic coordinate signal to a pre-stored geographic data base to acquire time and location of the pet collar 10. Next, the time and location are transmitted to the microprocessor 22. The wireless transmission circuit 23 is connected with the microprocessor 22, and can transmit information sent by the 10 microprocessor 22 to a remote server 30 wirelessly. According to the aforementioned components, when using the pet tracking system, the microprocessor 22 can acquire the location and time of the pet collar 10 from the GPS receiving circuit 21, and then transmit these information to the remote server 30 through the wireless 15 transmission circuit 23 for querying. Therefore, the location of that pet (e.g., a dog, a horse, a lamp or a pig) can be tracked by the remote server 30, so as to avoid that the pet is very difficult to be found after missing. Referring to FIGS. 1 to 4 again, a surface of the pet collar 10 is 20 made by a water-proof material to prevent from water intruding into the 6 pet collar 10. Referring to FIG. 3 and FIG. 4 again, a communication medium of the wireless transmission circuit 23 includes an RF (Radio Frequency), a GSM (Global System for Mobile Communications), a GPRS (General 5 Packet Radio Service), a CDMA (Code Division Multiple Access), a WiMAX (Worldwide Interoperability for Microwave Access) or a satellite to satellite communication medium. Referring to FIG. 3 and FIG. 4 again, the rechargeable battery 24 can be a lithium-ion battery and when its electricity is weakening, a 10 recharger (not shown in the drawings) can be used to connect to the rechargeable battery 24 for recharging. In one embodiment of the present invention, the rechargeable battery 24 is provided with an induction coil (not shown in the drawings), such that when recharging, a recharger which is provided with an 15 induction coil can be used to recharge the rechargeable battery 24 by a non-touching and electromagnetic induction method. Referring to FIG. 3 and FIG. 4 again, the rechargeable battery 24 can be connected to a solar cell (not shown in the drawings) for recharging by using the solar cell to convert solar energy to electricity, so 20 as to maintain sufficient power constantly. 7 In the other embodiment of the present invention, the GPS tracker 20 is provided with an electronic-gate-type wireless switch (not shown in the drawings), and a location, such as on a pet's owner, in a home or of a pet's house, is provided with at least one wireless signal transmitter (not 5 shown in the drawings), allowing that when the electronic-gate-type wireless switch receives a signal of this transmitter, the switch can be in an OFF state, and the GPS tracker 20 is changed to a sleeping and energy-saving mode. On the other hand, if the pet is away from that transmitter by a certain distance (such as outside 20m of diameter), then 10 the electronic-gate-type wireless switch will not be able to receive the signal of this transmitter and turn into an ON state, which changes the GPS tracker 20 to an activation state to track the location of that pet, so that the pet can be found very quickly. Therefore, in the sleeping and energy-saving mode, electricity consumption can be reduced largely. 15 It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims. 20 8
