Quantative analysis of School Child Physical Activity using Satelite as a Navigation System

本研究对人体运动进行了定量分析。学童携带GPS（全球定位系统）接收器。该接收机从卫星上获得定位数据。最初定位数据在100m以上，但使用差分GPS时，定位数据在20m以内。这个GPS系统显示了人体运动分析。但是这个系统的重量很大。如果，它会更小，它方便体育活动，特别是，学校的孩子。在未来的学校里，他将控制孩子们使用GPS接收器来测量身体活动。这种方法对分析人类活动是有效的。这种方法有望应用于福利，例如，检测流浪秩序人。

This study has cone quantative analysis of human movement. School Children have carried GPS (global Postioning System) recitver. This receieve gets a positioning data from satilite. At first, data of positioning were over 100m, but using differenciol GPS,dat were within 20m. This GPS system indicated human movenment analysis. But this system had heavy weight stally. If, it will be smaller, it convenient to physical activity, specialy, school children. In future school children will he contralled to measure physial activity by using GPS receiver. This method will be effective to analysis human actreity. And this method will be expected to apply wefare, for exampl, to detect wandering order people.
