摘　　要：利用自行研制的激光定轨软件CASMORD分析阿根廷圣胡安激光测距系统的SLR数据质量。结果表明,阿根廷圣胡安激光测距系统性能良好,具有较小的系统偏差(距离偏差和时间偏差),系统偏差稳定,随时间的变化较小,有效观测圈数和数据观测量处于全球台站前列;经系统偏差修正后,该系统达到了亚厘米级观测水平,具有较高的观测精度,可以为卫星的精密定轨提供在我国本土无法观测的轨道弧段的资料,为我国科学研究和国家的特殊需要提供必须的宝贵资料。Argentina San Juan Laser Ranging System was developed and maintained by three institutes, which are Chinese National Astronomical Observatory, Chinese Academy of Surveying and Mapping, Argentina San Juan University. The SLR data quality of Argentina San Juan Laser Ranging System is analyzed with orbit determination software CASMORD. The results reveal that the SLR system has smaller and much stablc range bias and time bias. The number of efficient observation pass and normal point stands in a front-line position among all SLR observation stations in the world. Its observation precision attains to sub centimeter level after corrected with system bias. Argentina San Juan Laser Ranging System can offer important satellite trace information that is not obtained on our native land for many important applications.
