Claim Text:
1. A GPS receiving apparatus, comprising: a memory which stores (i) course data representing a course, along which a plurality of corners are set as transit positions from a start position to a goal, and (ii) distance data indicating respective distances from the start position to the respective transit positions; a GPS receiver which detects a position based on GPS signals received from a GPS satellite; a motion sensor which detects motion and change in movement direction of a user; and a processor which is configured to: obtain a moving distance of the user based on the motion of the user detected by the motion sensor; determine, based on the obtained moving distance and based on a distance to each of the transit positions indicated by the distance data stored in the memory, whether the user has come within a predetermined distance to a next transit position along the course represented by the course data stored in the memory; determine, based on changes in the position detected by the GPS receiver and the motion and change in movement direction of the user detected by the motion sensor, whether the user has turned and passed through the next transit position along the course; start operation of the GPS receiver so that the GPS receiver receives GPS signals from the GPS satellite when it is determined that the user has come within the predetermined distance to the next transit position along the course; and stop operation of the GPS receiver so that the GPS receiver stops receiving GPS signals from the GPS satellite when it is determined that the user has turned and passed through the next transit position along the course, based on changes in the position detected by the GPS receiver and the motion and change in movement direction of the user detected by the motion sensor.
