Abstract

A cellular phone mounted player position as well as a hole position determining system for a golf course for use by players in playing the course is disclosed. Each of the cellular phone includes a monitor for displaying the golf course including each of the holes with its tee box, fairway, green, cup and hazards, as well as the position of the cellular phone unit on the course in real time. The distance between the target and the current position on a specific course of a golf club is measured when a player push the specific code number of a golf club followed by pushing the course number.

1 . A system for determining the location of golf holes in a cellular phone, the system including a base station determination of yardage for being adapted to operate on a differential global positioning system (DGPS) in conjunction with GPS satellites that transmit GPS satellite signal information for use in determining the relative position of and distance between targeted points a golf course, the system further including: base stations located on golf course targets, and each of the hand-held cellular phone stations for determination of the yardage, the functions of the system including the transmission and reception of information between the base stations and each of the hand-held cellular phone remote stations. 
   
   
       2 . The system of  claim 1  wherein the base station includes cellular phone for displaying the location of all remote stations in real time such that the remote stations including lent not limited to the golf green holes can be observed while in transit.
