of Sciences. The performance of the SLR system has been greatly improved since August 1997. The single shot precision is improved
from 5–7 cm to 1–2 cm and the normal point precision reaches 4–7 mm. The long-term stability is better than 1 cm. The amount
of observation has been increased from 1000 to over 3000 passes. The whole performance of Changcun SLR system has reached
the advanced level among the worldwide SLR stations.
