Abstract

본 발명은 위성위차 측정시스템(Global Positioning System : 이하, GPS)의 위치 데이타와 연계한 평균지연(avarage delay)을 측정하기 위한 방법에 관한 것으로, GPS를 기반으로 하는 위치측정 장치의 위치 데이타를 이용하여 송신점과 수신점의 실제거리를 산출하는 제1과정; 및 상기 수신점에서 관측된 파형으로부터 실제거리에 해당되는 시간지연을 보정하여 평균지연을 산출하는 제2과정으로 수행되는 것을 특징으로 하여, 평균 지연을 신속하고 정확하게 측정할 수 있는 효과가 있다.The present invention relates to a method for measuring an average delay associated with the position data of a Global Positioning System (GPS), using position data of a GPS-based position measuring apparatus. Calculating a real distance between a transmission point and a reception point; And a second process of calculating an average delay by correcting a time delay corresponding to an actual distance from the waveform observed at the receiving point, thereby measuring the average delay quickly and accurately.
