摘要： There is disclosed a portable GPS (Global Positioning System) receiver carried by a user. The receiver measures the distance traveled by the user and the speed. In the prior art technique, if satellites cannot be captured, no measurements are made. To find the distance and speed accurately, the measurements have to be performed continuously, thus increasing the electric power consumed by the receiver. The inventive receiver once finds the speed from the Doppler frequencies of the carrier waves. Then, a first distance-calculating means finds the distance from the speed. A walk-detecting means detects walking. A step number-calculating means accumulates the number of steps taken in steps. A stride-calculating means finds the stride from the accumulated step number and from the found distance. Then, a second distance-calculating means finds the distance from the stride and from the accumulated number of steps. A speed-calculating means finds the speed. The GPS receiver receives at regular intervals and updates the stride.

摘要： 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.
