Abstract
In this paper, SLR observations are used to validate the CODE precise orbit of GPS36 satellite. First, the comparison of orbit validation is performed by using the SLR normal point (NP) data provided by EDC and CDDIS from July 1 2013 to May 1 2012. Then, a long-term validation of the CODE precise orbit is carried out by using the SLR data from January 1 2003 to March 3 2014 of EDC. The results show that the number of SLR data provided by EDC is larger than those by CDDIS in the same time span, and the orbit validation results have a very good consistency by using EDC data and CDDIS data. The validation from ten years shows that SLR observation accuracy is about in one centimeter level. The data quality of SLR stations is relatively stable, and there is also a relatively stable system error between SLR observation and the computed range between satellite and station. The accuracy evaluated by the SLR data for GPS36 satellite is mostly less than 4 cm.
