Portable GPS positioning apparatus
First Claim
1. A portable GPS positioning apparatus for receiving a signal from a GPS satellite and measuring at least one of a position and a speed of the portable GPS positioning apparatus, the portable GPS positioning apparatus comprising:
- GPS receiving means for receiving a signal from a GPS satellite;
movement pitch detecting means for detecting the pitch of a repetitive movement of a portion of a human body corresponding to ambulatory motion of the human body;
timer means for determining an operating period at which to intermittently receive a signal from a GPS satellite to obtain positioning data used for determining the position of the GPS positioning apparatus;
stride calculating means for calculating, at a respective operating period, a stride of the human body during said ambulatory motion in accordance with positioning data corresponding to two positions and a movement pitch detected by the movement pitch detecting means during receipt of the positioning data; and
speed/distance calculating means for calculating, at a respective operating period, a speed and a distance of the ambulatory motion based on the stride determined by the stride calculating means and the pitch detected by the movement pitch detecting means.

Abstract
A portable GPS receiver receives a signal from a GPS satellite by a GPS receiving means to measure a position and a speed of the own receiver. A traveling pitch detector detects a traveling pitch of a human body. A timer determines an operating period to intermittently operate reception from the GPS satellite. A stride calculator calculates, on the operating period, a traveling stride from received positioning data between two points and a pitch detected by the traveling pitch detector during obtaining the positioning data. A speed/distance calculator calculates, on the operating period, a traveling speed and a traveling distance from the stride determined by the stride calculator and the pitch detected by the traveling pitch detector.
