Description

[Detailed description of the device]

[Field of Industrial Application] [0001] The present invention applies a differential, global, positioning, and system (hereinafter, abbreviated as DGPS) to a golf course from a given current position to the next pin or green predetermined point. The present invention relates to a distance measuring device for a golf course, which can accurately measure and display the distance to.

[Prior Art] When playing golf on a golf course, it is demanded to know the distance to the next pin. However, anyone can measure accurately with a simple operation. Distance device is undeveloped. Therefore, in order to know the distance from an arbitrary point to the next pin, there was no suitable distance measuring device, so visual measurement was performed. However, there are individual differences in vision and large errors in visual measurement, so accurate distance measurement was difficult.

[Problems to be Solved by the Invention] The present invention solves an inaccurate distance measurement due to a large visual difference between individuals when measuring the distance to the next pin on a golf course. It is a rangefinder for golf field that can easily and accurately measure the distance to the next pin or designated point on the green at any point.

[Means for Solving the Problems] The present invention is directed to a position correction meter for a pseudo position signal received from each artificial satellite by a GPS receiver of a mobile station carried by a golfer or a caddy at an arbitrary point on a golf course. At the reference station where the accurate installation position can be measured in advance, the GPS receiver receives the pseudo range, time information, orbit data signal from each artificial satellite, and the received pseudo position After detecting the error from the actual position and receiving the correction value data sent from the reference station by the wireless receiver of the mobile station and inputting it to the position correction calculation circuit at the same time, the current position of the mobile station is corrected and calculated. By comparing the golf course map where each pin position is recorded by the pin position calculation circuit. It is a DG PS applied distance measuring device for a golf course, which is characterized by calculating the distance to the next pin and displaying the distance numerically on a display.

[Operation] The operation will be described with reference to the embodiment shown in FIG. The base station A, which can measure the accurate position, and the mobile station B, which is carried by a golfer or an accompanying caddy, simultaneously receive the radio waves from each GPS artificial satellite and acquire pseudo position information, and the base station A receives the pseudo position information. An error between the position and the actual position is detected and wirelessly transmitted as correction value data. At the same time, the mobile station B receives the correction value data from the reference station A by the radio receiver 10, and the mobile station current position signal received from the satellite by the GPS receiver 7 and the received correction value data by the position correction calculation circuit. Input to 9 to correct and calculate the current position accurately, and then calculate the distance to the next pin by collating and calculating the golf course map data 14 at the next pin position calculation circuit 13 and displaying the distance. It is displayed on the container 15 in yards and meters.

Further, by providing the IC card interface 16, it is possible to record information such as distance and current position and time displayed on the display unit 15, time, hole number, number of strokes, etc. in the IC card.

[First Embodiment] First, the global positioning system (abbreviated as GPS) applied to the present invention is generally translated as a global positioning system. It receives radio waves from artificial satellites and measures the current position and altitude, and by measuring how long it takes for radio waves emitted from multiple satellites to reach the receiving point, This is a method to obtain the current position based on the distance. In addition, the differential system uses radio waves from artificial satellites to correct the pseudo range from each satellite in order to improve the positioning accuracy between two receiving points, and accurate position can be measured in advance. The error component is detected by the pseudo range from each satellite, time information, orbit data, etc. received at the reference station and transmitted as a correction value, and the user receives the wireless receiver of the user at any point. The correction value data is received by the GPS receiver, and the GPS signal simultaneously received from each satellite by the GPS receiver of the user is corrected by the correction value data. The present invention applies these two methods to the user's GPS receiver. By measuring the exact position, the distance to the pin or green designated point on the golf course is measured.

Next, the present invention will be described with reference to the embodiment shown in FIG. At a reference station A installed at a predetermined position in a golf course and capable of measuring an accurate position in advance, a GPS antenna 2 and a GPS receiver 1 receive pseudoranges, time information, orbit data signals from each artificial satellite, The error between the received pseudo position and the actual position of the reference station A is detected by the correction value calculation circuit 3, and the error component is wirelessly transmitted as correction value data from the wireless receiver 5 and the antenna 6 via the modulation circuit 4. .

On the other hand, at an arbitrary point in the golf course, a pseudo position signal received from each satellite by the GPS receiver 7 and the small GPS antenna 8 of the mobile station B carried by a golfer or an accompanying caddy is used as a position correction calculation circuit. Enter in 9. At the same time, the correction value data transmitted from the reference station A is received by the antenna 11 and the radio receiver 10 of the mobile station B, and the pseudo position signal is input via the demodulation circuit 12 to the position correction calculation circuit 9 described above. To the next pin position by comparing the current position of the mobile station B and calculating the current position of the mobile station B with the golf course map 14 in which each pin position of the green is recorded by the pin position calculation circuit 13. The distance is calculated, and the distance is displayed on the display unit 15 composed of a liquid crystal display in the number of yards or meters.

Further, by providing an IC card interface on the output side of the position correction calculation circuit 9, in addition to the distance displayed on the display unit 15, information such as the current position and time, the hole number, the number of strokes, etc. can be sent to the IC card. It is also possible to record.

[Effects of the Invention] This school plan was installed at a predetermined position where an accurate position can be measured and a pseudo position signal received from each artificial satellite by a portable mobile station at an arbitrary point in the golf course. Simultaneously receive the correction value data signal sent from the reference station to correct the pseudo position, measure the accurate current position of the mobile station, and then collate the golf course course map to determine the next pin or green. The distance to the designated point of is calculated, and the distance is displayed numerically on the display. Therefore, it has the effect of being able to easily and accurately know the distance to the designated point on the next pin or green that the golfer wants to know most.
