Abstract:
A method for measuring a distance and a direction between a golf ball positioned on a golf course and a pin on a green of a hole of said golf course in which the locations of both said golf ball and said pin on said green are undefined, comprising the steps of:a) positioning a first receiver means on or in the vicinity of said golf course;b) measuring a first distance and a first direction between said pin on said green and said first receiver means, without defining a location for said pin;c) positioning a second receiver means on or in the vicinity of said golf course;d) measuring a second distance and second direction between said golf ball and said second receiver means, without defining a location for said golf ball;e) operating said first receiver means for receiving a first global position signal data transmitted from navigation satellites translatable into a first location for said first receiver means;f) operating said second receiver means for receiving a second global position signal data transmitted from said navigation satellites translatable into a second location for said second receiver means;g) calculating said first global position signal data and said second global position signal data for deriving a third distance and a third direction of said third distance;h) mathematically combining said second distance and said second direction with said third distance and said third direction for calculating a fourth distance and fourth direction between said first receiver means and said golf ball;i) mathematically combining said first distance and said first direction with said fourth distance and said fourth direction for calculating a fifth distance and fifth direction between said pin and said golf ball.
