  • Patent number: 11086008
    Abstract: A golf ball tracking system, which includes a distributed sensor and processor system adapted to simultaneously track the trajectories of multiple golf balls hit by one or more golfers. The system is adapted to keep track of the location of the golfers to enable the allocation of shots to the correct golfer. The system is operated at a golf driving range, where multiple players can hit balls from anywhere within a designated area and/or fixed hitting bay locations.
    Type: Grant

  • Publication number: 20210228943
    Abstract: There is provided a skill level determination and management system and method. The system includes a sensor for automatically sensing shot data of a golf shot hit by a golfer on a range area towards a target on the range area. A comparing component is provided for comparing an end location of the golf shot to a target location and grading the shot, taking into consideration at least a difference between the end location of the golf shot and the target location, and a skill level associated with the golfer. A skill level management component is provided for updating the skill level associated with the golfer based on the grade.

  • Patent number: 10605910
    Abstract: The invention discloses a golf ball tracking system, which includes a distributed sensor and processor system adapted to simultaneously track the trajectories of multiple golf balls hit by one of more golfers. The system is adapted to keep track of the location of the golfers to enable the allocation of shots to the correct golfer. The system is operated at a golf driving range, where multiple players can hit balls from anywhere within a designated area and/or fixed hitting bay locations. Multilateration is used to determine the location of multiple targets in 3D space, based on the reported range and Doppler from distributed radar sensors.
