Abstract
A position determining system, a receiving system, a method of determining the position of a movable object and a method of receiving data regarding the position of the movable object are provided. The position determining system comprise a position determining unit, a display unit and a controller. The position determining unit determines the position of a movable object based on position information sent from GPS satellites. The display unit displays the position of the movable object which has been determined by the position determining unit. The controller controls a time interval at which the position of the movable object is determined by said position determining unit, in accordance with a degree of position change occurring in the position to be displayed on the display unit. Accordingly, in the position determining system, elimination of consumption power can be realized in a position determination process which is not necessarily performed, while the system is advantageously handled.
