Determining a position on a golf course is useful in several circumstances, however there are challenges in doing it with accuracy. Disclosed is a system for determining a position on a golf course, comprising a master unit and at least one slave unit, wherein the master unit and the at least one slave unit are adapted to communicate through a telecommunications network, wherein the master unit comprises a receiver for a satellite navigation system, the receiver being operable at a fixed position on the golf course, and wherein the master unit is configured to: obtain a position determined by the receiver; process the displacement between the obtained position and the fixed position; and make the processed displacement available to the at least one slave unit through the telecommunications network. A slave unit then makes use of the processed displacement to improve positions determined by itself.
