摘要
稠林矶信标台属于新增的内河RBN-DGPS台站,也是长江首座北斗/GPS双模差分信标台。该文主要采用GAMIT软件与IGS站整体平差,统一框架计算,从而获得稠林矶基准站精确成果。由于两次解算时间间隔较长,则对四年间的坐标进行了连续监测,验证该信标台基准站的稳定性,其水平和高程方向的精度均满足我国长江航运的导航需求,为长江下游以信标台为中心的300km航道提供高精度的导航服务。
The Choulinji Beacon Station is a newly added RBN-DGPS station for inland river and the first Beidou/GPS dual-mode differential beacon station in the Yangtze River.This paper mainly uses GAMIT software and IGS station overall adjustment,unified the frame calculation,so as to obtain the accurate results of Choulinji Beacon Station.Due to the long time interval between the two solutions,the four years coordinates of the beacon station are continuously monitored to verify the stability of the reference station of the beacon station.The accuracy of the horizontal and vertical directions all can meet the navigation requirements of the Yangtze River navigation in China,and the high-precision navigation services is provided for the 300 km channel centered on the beacon station in the lower reaches of the Yangtze River.
