Abstract:Based on the platform of typical SLR system, according to generation flow of SLR measurement data, extracting the difference between satellite measurement and calibration, measuring and analyzing the influence of various factors due to range bias of SLR measurement data, and technical approaches to improve the stability of SLR measurement data is provided in the paper. After applying the above research results, the long-term stability, short-term stability, and normal points accuracy of Lageos satellite at Shanghai SLR station, have been decreased from 12.7 mm, 22.7 mm and 2.0 mm in 2014 to 4.1 mm, 9.3 mm and 1.0 mm in 2015 respectively, which firstly reached the data quality standards of ILRS (10 mm, 20 mm, and 5 mm) in China ,and also improve international position in the field of SLR and the weight of observational data, with good prospects for promotion and application.
