Abstract

A golf information and management system utilizing the Global Positioning System, a satellite based, radio navigation system where clocks signals are transmitted. This satellite system provides at least four satellites (2) "in view" at all time. A golf cart (12) or player receives the signals from the four satellites, compares the clocked signals and an on-board computer reads the clocked signals and determines the position, in three dimension, of the receivers (velocity of the receivers is also available). There is a fixed base location (8) on the golf course that also receives the satellite signals and transmits a differential correction signal, via another channel, to the golf cart or player, where the computer determines the position of the cart or player to within a yard. The computer may be pre-loaded with golf course information, such as pin position, hazard positions, etc., where the computer via a graphical display (18) communicates to the player exact distances to the pre-loaded known physical features of the golf course, and displays information needed by the player to determine his next shot, including a video presentation of a golf pro'"'"'s suggestions. In addition, the cart may communicate with the base station where the base station can track each cart or player on the course. With such information, detecting slow players to allow better course management, and also allows the base station to output information to a cart to show the players ahead so as not to hit into other groups and to send messages to carts to urge faster play to send out other type messages.

Claims

1. Apparatus for providing golf play and management information to a golfer playing a golf course comprising:

(a) a first receiver constructed and arranged with the golfer to accept satellite signals from at least three sources, and to convert said satellite signals into first computer readable signals, wherein said first computer readable signals provides information for determining locations,

(b) a second receiver constructed and arranged with the golfer to accept, at least, a correction signal, and to convert said correction signal into second computer readable signals, wherein said second computer readable signal provides information for correcting location information

(c) computer means that accepts the first and second computer readable signals, said computer means pre-loaded with information relevant to playing the golf course,

(d) means to send the first and second computer readable signals to said computer means, where the computer means determines corrected relative locations on the golf course,

(e) display means in communications with said computer to report the corrected relative locations to the golfer, and

(d) a base station and communication means for sending the location of the golfer to the base station, and wherein the second receiver also receives information on the locations of other golfing groups to prevent hitting into the groups and where the locations of the groups are displayed on said display means.

2. Apparatus as defined in claim 1 wherein the pre-loaded relevant information includes the location and shape of all features in play on the course - tees, fairways, rough, contours, trees, bodies of water, sand traps, greens, clubhouse, parking lots, the pin on the green, all the hazards and out-of-bounds in play, the relative vertical heights, the distance to the doglegs, wherein the computer via the display means communicates the distance of the cart to all said features.

3. Apparatus as defined in claim 2 wherein the display means comprises video means to display suggestions on playing from a particular location.

4. Apparatus as defined in claim 1 wherein the satellite system includes the Global Positioning System using the Navigational Satellite Timing and Ranging where the satellite signals include clock information, where the computer means includes an internal clock, and where the computer means compares the received clock information to the internal clock to determine the position of the golfer.

5. Apparatus for providing golf play and management information to a golfer playing a golf course comprising:

(a) a base station of known location,

(b) at least two receivers constructed and arranged at the base station to accept satellite signals from at least three sources, and to convert said satellite signals into first computer readable signals, wherein said first computer readable signals provides redundant information for determining locations,

(c) computer means constructed at said base station that accepts the first computer readable signals, calculates the location of the base station, compares the base station known location to the calculated location and therefrom generates correction information,

(d) means for transmitting, constructed at the base station, to send, at least, the correction information,

(e) a cart,

(f) a cart receiver constructed and arranged on the cart to accept satellite signals from at least three sources, and to convert said satellite signals into second computer readable signals,

(g) cart computer means that accepts the second computer readable signals and generates therefrom location information of the cart,

(h) a second receiver constructed and arranged on the cart to accept, at least, the correction information and to correct the location information of the cart,

(e) graphical display means in communication with one of the computer means, said display constructed on the cart to accept, display and report, at least, the corrected cart location information, and

(d) communication means for sending the location of the golfer to said base station, and wherein said second receiver also receives information on the locations of other golfing groups to prevent hitting into the groups and where the locations of the groups are displayed on said display means.

6. Apparatus as defined in claim 5 wherein said cart is a golf ranger cart wherein the display shows all golfers playing on the course and means for the ranger cart to communicate with the other carts on the course such that a ranger can manage said golfers.
