Abstract: Systems and methods for determining the at-rest position of the golf ball of one or more golfers during tournament play. Beacons worn either by a golfer or another person associated with the golfer's playing group collect or receive a location signal from one or more global navigation satellite system (GNSS) satellites, wherein the signal's accuracy can be enhanced using real time kinematic (RTK) correction data. Location signals collected or received by the beacons are requested by, and transmitted back to, a portable device in radio frequency (RF) communication with one or more of the beacons and operated by the user. Methods and systems of the present invention can also utilize a laser rangefinder, operated by the user, to measure line-of-sight distance, inclination angle, and azimuth to a golfer's golf ball from the user's determined GNSS location when the beacon is worn by the user.
