Method and System for Measuring Distance Between Points on Golf Course by Using Global Positioning System}

The present invention relates to a method and apparatus for measuring a distance of a golf course, and more particularly, to grasp a current location of a golf course of a user of a wireless communication terminal using a global positioning system (GPS). The present invention relates to a golf course distance measuring method and system for providing a wireless Internet service by calculating a distance from the identified current location to a target location in a golf course designated by a user.

In golf games, higher scores can be achieved if the player is familiar with a particular golf course. If the player is unfamiliar with the golf course or before playing on a competing golf course, the golfer is preferably familiar with the terrain of each hole. For example, whether the hole is inclined to the left, to the right or straight, whether there are obstacle areas such as sand traps, bunkers and puddles, or from the current position of the golfer (or golf ball), front, rear, pin, You must have knowledge of the critical obstacle area or distance to the desired layup location for the green approach.

Several methods have been proposed for obtaining distance information from a current position to a desired target position on a golf course. One of them is provided with a distance marker (Marker) indicating the distance along the path of each hole so that the player knows the distance to the center of the green. Another method is to calculate the distance from the current position to the hole by using a telescope measuring device, and to display the placement characteristics for each hole and the distance from the some position along the hole to the center of the green. Use the course information booklet.

These distance markers, distance measuring equipment, and golf course information booklets provide information about hole placement and obstacle area locations on the golf course, and also allow you to measure the distance from the ball to the closest distance marker to the distance from the ball to the center of the green. To predict. This method is not accurate but helps improve the information about the hole and thus the game.

However, unlike professional golfers, amateur golfers who enjoy golf as a hobby have a considerable difficulty in measuring the distance from the current position to the hole in a large space such as a golf course due to lack of experience. As a result, amateur golfers usually rely on the experience of the caddy or roughly estimate the remaining distance from the current location to the hole on the golf course.

As such, amateur golfers have a problem in that the accuracy of shots is reduced because they roughly calculate the distance from the current position to the hole on the golf course based only on the recommendations of others and their own vision and senses.

Therefore, an object of the present invention is to determine the current position in the golf course of the user of the wireless communication terminal by applying the GPS technology, to calculate the distance from the identified current position to the target position in the golf course specified by the user to the wireless Internet It is to provide a method and system for measuring golf course distance.

It can be applied to various fields and situations such as navigation and logistics control, location based customer relationship management (CRM).

In order to use the location-based service, it is essential to know the location of the wireless communication terminal 110. Currently, as a method of determining the position of the wireless communication terminal 110 using wireless communication, a method using GPS is representative.

GPS is a system that can be located anywhere in the world by 24 GPS satellites orbiting the earth at an altitude of about 20,000 kilometers. GPS uses radio waves in the 1.5 GHz band, and on the ground there is a coordination center called Control Station, which collects and synchronizes information transmitted from GPS satellites, and the wireless communication terminal 110 uses a GPS receiver. Know where you are In general, triangulation is used as a method of positioning using a GPS system. Three satellites are required for triangulation, which requires a total of four GPS satellites, including one observational satellite for time error.

In more detail, in GPS, since the position of each of the three satellites is already known, the GPS is positioned by measuring the distance between the satellite and the GPS receiver in the wireless communication terminal 110. The distance from the satellite to the GPS receiver in the wireless communication terminal 110 can know the propagation time from the difference between the time transmitted from the satellite and the time received by the GPS receiver with a built-in clock.

Is reserved for reserve. The positioning of the positioning satellites is specially designed such that at least four satellites are always visible all over the earth to calculate the three-dimensional position of the wireless communication terminal 110 and the error of the clock embedded in the wireless communication terminal 110. . The navigation data transmitted from each positioning satellite 100 includes a PRN code (Pseudo Random Noise) specially designed according to the number of each positioning satellite. That is, since navigation data is transmitted to the wireless communication terminal 110 in a code division multiple access (CDMA) method, the wireless communication terminal 110 accurately receives the navigation data transmitted from each positioning satellite 100. can do.

The location of the wireless communication terminal 110 displayed on the map of the golf course will be displayed at the new location as the user moves the golf course.

The user may request a distance measurement from the current location of the golf course to the target location by selecting a desired target location, for example, a hole, on the map of the golf course displayed on the screen of the wireless communication terminal 110. The method of selecting a desired target position may be performed by selecting a desired hole number from a numeric button of the wireless communication terminal 110. Of course, the golf course distance measurement can be requested at any position of the golf course as well as selecting the position of the hole or the green using the number. This may be possible by providing a cursor on the map of the golf course illustrated in FIG. 3B and allowing the user to move the cursor to select the desired location.

The golf course distance measurement server 160 converts the distance on the map from the current position on the map to the target position through the map server 180 into the actual distance according to the distance measurement request for the target position selected by the user. 110) (S218).

At the bottom of the map of the golf course of FIG. 3B is a distance measurement window 320 in which the distance provided by the golf course distance measurement server 160 is displayed. In this case, since the position of the wireless communication terminal 110 displayed on the map of the golf course is updated and displayed at a new position as the user moves the golf course, the distance measurement window 320 of the wireless communication terminal 110 is displayed to the user. For the target position selected by the user, the distance from the current position to the target position will be automatically displayed even if the distance measurement is not requested again.

Therefore, the user may check the distance value displayed on the distance measurement window 320 of the wireless communication terminal 110 and select an appropriate golf club to increase the accuracy of the shot.
