Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for guiding a golf course using GPS satellite radio waves for confirming the flight distance of a ball on the golf course and the remaining distance from the second point to the green. It is about.

[0002]

2. Description of the Related Art Conventionally, a method of checking a distance on a golf course has been a method of relying on each person's memory or step count depending on the number of rounds of the course, or visual check or intuition at a target object installed on the course. Was widely used.

[0003]

[Problems to be Solved by the Invention] In the method of confirming the distance, all of the conventional methods are only about confirmation, and their accuracy is very doubtful. The accuracy also varies greatly among individuals. After all, I couldn't always check the correct flight distance. The present invention solves the above-mentioned drawbacks and enables anyone to easily and quickly confirm an accurate distance.

[0004]

At present, as this kind of technique, it is already widely used as a navigation system for automobiles, and its basic position confirmation technique,
That is, when the satellite radio waves including the orthogonal coordinates (x, y, z) with the earth as the origin of each satellite and the time signal are received from three or more GPS satellites, the position of each satellite at the receiving location, The straight line distance is calculated from the transmission speed of satellite radio waves, the relational equation is obtained by the procedure of triangulation, the reception position is calculated, and when four or more satellite radio waves are received, the altitude is measured by the same method as the position measurement. As an application of the above-described technology for performing three-dimensional positioning including the above, the present invention firstly proposes that the main body (9) has a GPS as the structure of the system.
A GPS antenna unit (4) for receiving radio waves from satellites,
A GPS receiver section (5) for calculating the latitude, longitude and altitude of the current position on the ground from the signal is provided. Also, an IC card (8) that contains map data of golf course details
Etc. are connected to the main body (9), the current position determined by the GPS receiver section (5) above is combined with the map data of the golf course recorded in the IC card (8), etc., and the result is combined with the visual controller section ( A display processor unit (6) for outputting to 7) is provided. The visual controller section (7) is provided with a GPS operation key for searching and displaying information recorded in the IC card (8), a TV monitor for displaying a signal input from the display processor section (6) as an image, and the like. A golf course guidance method using GPS satellite radio waves, comprising the above method.

[0005]

[Operation] When playing on each golf course, display the detailed map of the course in advance and carry the device with you. If you want to know the flight distance of the tee shot of each round hole,
By inputting the tee shot location and inputting again at the position where the player walked to the second shot point after the tee shot, the flight distance of the tee shot can be confirmed by the straight line distance between these two points. Also, the distance from the second shot point to the center of the green, etc., to the drop location of the second shot can be confirmed by inputting the destination location.

EXAMPLES Examples of the present invention will be described below. (A) From a plurality of GPS satellites (1), (2), and (3) moving in an orbit around the altitude of 21,000 km,
An omni-directional small plane GPS that receives consumer satellite radio waves containing information such as the position and time of satellites radiated to the ground.
The antenna part (4) is provided in a part of the main body (9). (B) GP that calculates the latitude, longitude, and altitude of the received position from three or more satellites in the manner of triangulation.
The S receiver part (5) is provided in a part of the main body (9). (C) I, which contains a detailed map of each golf course in advance
A recording medium such as a C card (8) is attached to the mounting portion of the main body (9), and the current position calculated by the GPS receiver unit (5) is combined with the map recorded in the IC card (8),
A display processor section (6) for outputting it as a signal to the visual controller section (7) is provided in a part of the main body (9). (D) The visual controller section (7) has an IC
G for searching and displaying the information recorded on the card (8)
PS operation keys and display processor section (6)
A TV monitor that displays the input signal as an image is provided. The present invention has the above-described configuration, and further provides means and principles relating to the basic method for confirming the positioning position of the present invention.

[Figure 2] Basic calculation formula x ₀ ² + y ₀ ² + z ₀ ² = fixed (x ₁ .y ₁ .z ₁ ): Cartesian coordinates of each satellite (x ₀ .y ₀ .z ₀ ): Orthogonal coordinates of the location C: Satellite radio wave Transmission speed τ _t : Satellite radio wave transmission → reception time Δ _t : Loss time required for judgment inside the device Calculate the linear distance from each satellite to the positioning position by the above formula, and the intersection is the positioning position. Therefore, the positioning location can be found by deriving and solving the relational equation. Further, when using this, an IC card (8) or the like on which a course map to be rounded first is recorded is attached to the main body (9) and a detailed map of the course is displayed. The device body (9) is carried by the user, and the present position is measured when and where it is needed. If you want to know the flight distance of the tee shot, first input the tee shot location to the main body (9), walk to the second shot point after the tee shot,
By re-inputting the position just above your own ball position and finding the distance between the two points, you can find the flight distance. When you want to know the distance from the second shot position to the center of the green, such as the center of the green, enter the ball position of the second shot into the main body (9) and set the desired place to hit from the main body (9). Input on the displayed map screen. Then, the remaining distance can be confirmed by obtaining the distance between the two points. Also, the distance to the bunker in front of the green etc. can be known by repeating this operation.

[0007]

As described above, the confirmation of the flight distance of the ball, the required flight distance of the next shot, etc., is unprecedented, and it is said that the experience of repeating rounds on the course and the sighting or the gait However, there are many parts that rely on intuition, and all of them are methods that lack accuracy, and for beginners and those who are not familiar with the course, there was no reason to hope for score improvement. The present invention is free from the conventional inaccurate distance confirmation, and anyone can perform an accurate distance confirmation method.
