Abstract
Virtual golf system for playing golf, comprising a plurality of trackable golf balls, wherein each golf ball comprises transmitting means for broadcasting electromagnetic beacon signals for detecting a position of the golf ball, a position determination unit comprising three receiving antenna'"'"'s arranged for receiving beacon signals broadcasted by any of said plurality of trackable golf balls, and wherein said position determination unit is arranged to determine a position of said golf ball on a driving range based on time differences of a broadcasted beacon signal received by said receiving antenna'"'"'s. A plurality of trackable golf balls and a plurality of players may be active at the same time. Trackable golf balls may be paired with specific players. A game controller advances a virtual game of golf each time a trackable golf ball is stroked by a player.
