Abstract
A positioning apparatus is arranged by a timepiece unit which is continuously operated, and also a GPS (global positioning system) receiving unit which is operated only when a present position of the own positioning apparatus is measured. A first counter for producing reception timing is provided in this GPS receiving unit, and a second counter is provided in the timepiece unit so as to stop the GPS signal receiving operation by this GPS receiving unit. After the second counter is synchronized with the first counter, the power supply of the GPS receiving unit is turned OFF. When the GPS receiving unit is restarted, the first counter is synchronized with the second counter.
