[Prior Art] In recent years, with the increasing function of the Global Positioning System (GPS) and the decreasing price, the use of global satellite navigation systems has become more and more frequent, not only for handheld global satellites. Positioning system devices, on various vehicles, navigation devices have gradually become standard equipment. By configuring the navigation device, the driver can avoid the delay and time wasted caused by unfamiliarity with the environment. The operation principle of the conventional global satellite positioning system is as shown in FIG. 1 , wherein the navigation device 11 is connected to at least three artificial satellites 10, and the navigation device 11 corresponds to the navigation device 11 corresponding to the radio wave communication time of each artificial satellite 10 respectively. The relative distance of each artificial satellite 10 is matched with ephemeris data (Ephemeris) containing information about each satellite (for example, satellite number, trajectory, time, position, angle, etc.), and the intersection of the navigation device 11 is obtained. Then, the display module built in the navigation device 11 can be used to display the positioning information for navigation purposes. In the prior art, the navigation device 11 usually attempts to download the latest ephemeris data from the artificial satellite 10 after booting up, in order to facilitate subsequent arithmetic processing. In general, after the navigation device 11 is turned on, it may take about 5 seconds to search for the satellite signal, and it takes about 30 seconds to download the ephemeris data from the artificial satellite 10; if during this period, the signal is poor. In the event of a disconnect, the action of downloading the data must be reopened at 5 1343471. It is conceivable that the first connection of the navigation device 11 to the artificial satellite ίο after the booting is not only takes too long, but also requires multiple connections and downloads due to poor signal, etc., for the user, the use Quite not convenient. To improve the above problem, there is another solution in the prior art called the Assisted Global Positioning System (AGPS), as shown in Figure 2. The assisted global satellite positioning system is usually a handheld navigation device, such as a mobile phone 13 with navigation function, which uses its own mobile communication capability to download pre-stored ephemeris data from the mobile phone base station 15 to enable navigation functions. When the mobile phone 13 is first connected to the satellite, it does not need to request the ephemeris data from the satellite 10, but instead downloads it from the mobile phone base station 15 'However, because this type of download is provided by the tracker The user must pay an extra fee' resulting in increased usage costs. In view of the above, the present invention provides a global satellite positioning system and a data transmission method thereof that can solve the above problems and are available for use in the vehicle to improve the above-mentioned problems to be solved in the industry. SUMMARY OF THE INVENTION The present invention is directed to providing a global positioning system for a vehicle and a data transmission method thereof. [Using a portable electronic device to access a wide area network from a (four) Is pre-downloaded star layer data] The star layer data is transmitted to a navigation electronic device. In this way, it can solve the shortcomings of the long-time downloading of ephemeris data when the first global satellite connection is connected to the satellite after the start-up of the global satellite (4), thereby greatly shortening the time required for the global satellite positioning system to enter the operation screen after being turned on; In particular, when the satellites in the position of the global satellite positioning system are not good enough, (4) it is impossible to download the star-level data in a specific B-capture, and it must be re-downloaded, resulting in the lack of smooth operation of the global satellite positioning system. 1343471 Another object of the present invention is to provide a global positioning system for a vehicle and a data transmission method thereof, which utilizes a portable electronic device to access the wide area network, so that the user only needs to pay when downloading the ephemeris data. The basic communication cost of the portable electronic device, or even the free download, does not require the additional cost of downloading the ephemeris data from the mobile communication base station, for example, to assist the global satellite positioning system. To achieve the above objective, the present invention discloses a global positioning system for a vehicle, comprising a server, a portable electronic device and a navigation electronic device. The server stores ephemeris data, and the portable electronic device can be driven from the servo.

It should be noted that the transmission mode used by the present invention can be connected to the server 35 as long as it is a variety of data communication protocols for the portable electronic device 33 to connect to the network and communicate, and then download the ephemeris data. This is not limited here. For example, the portable electronic device 33 of the present embodiment is a mobile phone, and the ephemeris data is downloaded from the specific server 35 after being connected to the wide area network by using the mobile phone base station; or, if the mobile phone base station is integrated The server 35 directly provides the service of downloading the ephemeris data. At this time, the server 35 is an assisted Global Positioning System (AGPS) server. In other embodiments, the global positioning system for vehicle 30 can include a computer host (not shown). The computer itself is connected to the server 35 via a computer network, and the portable electronic device 33 When connected to the host computer by wired transmission (for example, using a universal serial bus) or wireless transmission (such as Bluetooth), the ephemeris data can be pre-downloaded from the server 35 by using the computer network. In addition, the navigation electronic device 3 can synchronously receive satellite signals from the artificial satellite 10 1343471 during operation. In detail, the transmission time of the Keai satellite radio wave signal is converted into the relative distance between the navigation electronic device 31 of the present invention and each of the artificial satellites. Moreover, the portable electronic device 33 further transmits the ephemeris data downloaded from the server 35 to the navigation electronic device 3, whereby the navigation electronic device 31 calculates the position information according to the star shield data and the % star. To complete satellite positioning and provide navigation information to users. In the above configuration, the navigation electronic device 31 is disclosed.
