青岛市连续运行基准站系统(QDCORS)稳定性分析
Stability Analysis of Qingdao CORS Reference Stations
摘要
Abstract
In this paper,GNSS observational data from the Qingdao continuously operating reference station system(QDCORS) from 2014 and 2015 are processed by GAMIT / GLOBK software combined with 16 IGS stations.The regional network calculation of ITRF2008 is acquired by time series analysis of coordinates.The variation trend between QDCORS and the surrounding stations of the crustal movement observation network of China is nearly consistent,with horizontal velocity of 34.41 mm/a in the direction of E19.62°S under ITRF2008.Using one fiducial station as a fixed reference,the velocity of other fiducial stations is around 1 mm/a horizontally and less than 5 mm/a vertically,which reflects the overall stability of QDCORS.Con sidering the environment of fiducial stations,the conclusion can be made that the main factors causing anabnormal fiducial station is the multipath effect of GNSS and urban construction procedures.关键词
