Calculation Of Station Coordinates Based On SLR

In recent years,with the rapid development of geodesic technology in space,there is an increasing demand for high precision and high quality scientific research results.Various disciplines and fields urgently need high precision earth reference framework as support.Accurate determination of SLR station coordinates is of great importance to the establishment and maintenance of high precision International Terrestrial Reference Frame(ITRF),the study of plate motion and texture motion.Based on this,the following work is carried out in this paper:1)Coordinate calculation based on SLR.The range data of four satellites were selected,and the calculation strategy was formulated based on the precise orbit determination technology.The station coordinates of five SLR stations in China were calculated by using GEODYN ? software.The time series of X,Y and Z coordinate components of five stations are obtained.2)Analysis of calculation results.The results of the calculation of SLR7237 station were compared with the data of ILRS,and then the MORLET wavelet analysis of the results of the calculation of SLR7237 Changchun station was carried out on the MATLAB platform to analyze the time-varying law and physical mechanism.3)Program implementation.Design an automatic station coordinate calculation software.This paper analyzes the software requirements,introduces the software design process and functions,and finally packages and packages various programs used in the calculation to form a visual software interface.
