Abstract
In response to the difficulty of directly obtaining CGCS2000 coordinates in areas lacking network signals and with insufficient CORS coverage,this paper proposes a high-precision autonomous solution method based on joint observation with international IGS tracking stations.GNSS observation data in the survey area are simultaneously collected,and contemporaneous observation data from IGS tracking stations are downloaded.The high-precision baseline processing is then performed using GAMIT/GLOBK software.The results are then transformed to the ITRF97 framework at epoch 2000.0 through ITRF frame transformation and epoch transformation models,and finally,the CGCS2000 coordinates of the survey area targets are obtained through network adjustment.Validation using a water conservancy project control network construction as an example shows that the plane position discrepancies between the coordinates obtained by this method and those from traditional control survey methods are no more than 1.3 centimeters,meeting the accuracy requirements of high-grade engineering surveys.This method enables the acquisition of CGCS2000 coordinates in remote areas without network or CORS services,with strong practical value.关键词
