A global position satellite receiver (GPS receiver) is located in a fixed, undefined location on or in the vicinity of a golf course. The distance and direction between the fixed GPS receiver and a pin or object on the golf course is measured using conventional distance and direction measuring apparatus. This is a first measured leg. A mobile GPS receiver, with computer, is on the golf course. A golf ball is in the fairway of the hole. The fixed GPS receiver receivers first global position satellite signals (GPS Data) from global position satellites in orbit above the earth, the first GPS Data defining a location for the fixed GPS Receiver. The mobile GPS receiver receives second GPS Data from the global position satellites which define a location for the mobile GPS receiver. Both sets of GPS Data are identically contaminated and both location definitions are unreliable in accuracy. The first GPS Data and the second GPS Data are mathematically calculated to derive the distance and direction between the fixed GPS receiver and the mobile GPS receiver. This is a derived leg. The distance and direction between the mobile GPS receiver and the golf ball on the fairway are measured using conventional distance and direction finding apparatus. The is the second measured leg. The derived leg and the second measured leg are mathematically combined to calculate the distance and direction between the fixed GPS receiver and the golf ball. This is the first calculated leg. The first measured leg and the first calculated leg are mathematically combined to calculate the distance and direction between the ball on the fairway and the pin or object. 59
