Abstract
A global position receiver receives navigation signal from navigation satellites, in space, from a fixed location on a golf course, the location defined in stable location data. Location data derived from the navigation signals defines the fixed location in unstable location data. The stable location data and the unstable location data are compared for generating an error signal. A mobile global position receiver, on a fairway of the golf receives concurrently transmitted navigation signals from the navigation satellites from an undefined location. Location data derived from the navigation signals by the mobile unit defining the location of the mobile unit in unstable location data is combined with the error signal generating stable location data defining the undefined location of the mobile unit on the fairway. The distance and direction of a golf ball from the mobile unit, are measured. The stable location data, defining the location of the mobile unit, is combined with the measured distance and direction and stable location data defining the location of the golf ball is obtained, The distance between the golf ball and the hole on the green, the location of which is fixed and known in compatible location data, is measured by simple mathematics.
