Abstract: A Global Positioning System (GPS) is provided for use by golfers in their golf carts, which supplies useful yardage information to the golfer without the need for frequent manual maintenance by the golf course. Furthermore, the inventive system also comprises a highly effective advertising medium for reaching golfers at the golf course, without being unduly obtrusive. A business method related to providing the GPS system to golf courses benefits those courses by permitting them to obtain the system at no cost, and, in fact, typically at a substantial financial gain, and also permits them to obtain updated and improved golf carts at a substantial discount. Golf courses also benefit because of faster resultant play by golfers on the course, thus permitting them to consider offering more tee times.
