ZJCORS(浙江省连续运行参考站系统)自2010年10月投入运行以来尚未进行坐标时间序列分析。通过收集近两年来采集的观测数据,采用Bernese V5.0软件进行基线解算与平差,结果表明:2012年7月,站点坐标与启用成果比较“鄞州”站点X方向最大偏移量28 mm(向南),“石浦”站点Y方向最大偏移量27 mm(向西),“鄞州”站点沉降91 mm。文章分析了产生形变原因。
ZJCORS(浙江省連續運行參攷站繫統)自2010年10月投入運行以來尚未進行坐標時間序列分析。通過收集近兩年來採集的觀測數據,採用Bernese V5.0軟件進行基線解算與平差,結果錶明:2012年7月,站點坐標與啟用成果比較“鄞州”站點X方嚮最大偏移量28 mm(嚮南),“石浦”站點Y方嚮最大偏移量27 mm(嚮西),“鄞州”站點沉降91 mm。文章分析瞭產生形變原因。

Although ZJCORS ( Continuously Operating Reference Stations in Zhejiang ) has been running from Octo-ber 2010 ,but the time series analysis of coordinates has not been doing for ZJCORS .In this paper ,two years of observa-tion data were calculated and adjusted by using Bernese V 5.0.The experimental results shows that the station of YINZ have X coordinate offset of 28mm(to south) from October 2010 to july 2012,the station of SHIP have Y coordinate offset of 27mm(to west),the station of YINZ had been subsided for 91mm.The reason of deformation had been analysed .
