Abstract

In this paper, we analyzed the influence of different observation stations distributions on satellite clock offset estimation based on the PANDA software. The result shows that, when the distance between stations is shorter than 200km, the correlation of troposphere parameter and satellite clock offset parameter is strong, the accuracy of satellite clock offset estimation will be up to 0.8ns; when the distance between stations is up to 500km, as the correction of troposphere parameter and satellite clock offset parameter is significantly reduced, and the two kinds of parameters can be distinguished.

본 논문에서는 관측소 지리적 위치에 의한 대류권 파라미터에 따른 위성 클럭오차 특성을 분석한 것으로 PANDA 소프트웨어를 이용하여 관측소 거리의 간격에 따른 GPS 위성 클럭오차에 따른 정밀단독측위의 성능을 연구하여 결과를 제시하였다. 분석 결과에 의하면 거리의 간격이 200km 이하인 경우에는 대류권 파라미터와 위성 시계 오차 파라미터의 관련성이 크며, 최대 0.8ns의 클럭 오차를 발생하였다. 또한 거리의 간격이 500km이상인 경우에는 위성 클럭 오차와 대류권 파라미터의 관련성이 현저하게 감소됨을 알 수 있었다.
