BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a golf course guidance system, and more particularly to a golf course guidance system that applies the concept of a so-called GPS system.

0002

2. Description of the Related Art Conventionally, so-called self-contained navigation devices have been used as positioning devices for various moving objects such as automobiles, aircraft, and ships. This self-supporting navigation device calculates the two-dimensional displacement (vector amount) of a moving object from the direction data from the direction sensor and the speed data from the speed sensor, and calculates the current position by integrating this two-dimensional displacement with a reference point. It was what I was looking for. For example, in the case of a car, the number of pulses that occur during one revolution of the drive shaft is set in advance, and the distance calculated from the total number of pulses that occur from the reference point to the current position is multiplied by a distance correction coefficient. Mileage was required.

[0003] Furthermore, GPS (Global Positioning System) is a positioning device that uses artificial satellites.
tem ) type navigation device has been developed. This GPS type navigation device usually has three or more GPS
It is configured to receive radio waves from S satellites and measure the position of the receiving point from pseudorange data including the receiver time offset between each GPS satellite and the receiving point, and the position data of each GPS satellite. .

[Problems to be Solved by the Invention] However, this GPS system is effective for moving objects that travel over a certain distance and at a certain speed, but when the moving distance is short and the moving speed is low. The error becomes large and there are many practical problems. Incidentally, it is important for golf players playing on a golf course to confirm their own position when playing or practicing, but at present this is often based on the player's own visual estimation, experience, or sense. The above-mentioned GPS system also has problems in terms of travel distance and travel speed when applied to golf courses.
