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。学校的孩子们都带着GPS（全球定位系统）接收器。这个接收器从卫星接收定位数据。最初定位数据在100米以上，而差分GPS定位数据在20米以内。该GPS系统显示人的运动分析。但该系统具有很大的局限性。如果是这样的话，它会更小，更方便体育活动，特别是学校的孩子。在未来的学校里，孩子们将被控制使用GPS接收器来测量身体活动。该方法对分析人体活动是有效的。该方法将有望应用于例如检测流浪秩序人等的检测中。

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.
