A GPS signal receiving section measures a Doppler frequency of a carrier wave to output a three-dimensional velocity vector to a CPU 100. The CPU 100 calculates a cumulative distance from a signal receiving interval and velocity data to compare between the cumulative distance stored in a RAM 104 and the distance point data previously stored in the RAM 104. Where the cumulative distance exceeds the distance point data, a lap time is calculated and displayed on a display section 106 based on the time count data sent from the time count circuit 105. Further, the CPU 100 calculates and displays on the display section 106 a time to arrive at the predetermined moving distance from the velocity data, the cumulative distance and the predetermined moving distance stored in the RAM 104.
