2018年第一季度观测情况：

        从表1可以看出，每个激光测距站的基本观测圈（卫星的一次通过）数比以前的1800大幅度提高了。应该是和激光器的发展有关。随着半导体激光器的普及，千赫兹频率的激光脉冲用于卫星激光测距观测，使得采集数据的效率大大提高。此表中，我国的四个站是长春、北京、上海、昆明（年初实现了月球激光测距）。

                                            Table 1

表1中各栏的含义：1-2：分别为站名、站号，3-5：过去12个月的低轨卫星、地球动力学卫星和高轨卫星的圈数；6：12个月的总圈数、7-9过去12个月的低轨卫星、地球动力学卫星和高轨卫星的正则点数。

• Column 1 is the station location name.

• Column 2 is the monument marker number.

• Column 3 is the LEO pass total during the past 12 months.

• Column 4 is the LAGEOS pass total during the past 12 months.

• Column 5 is the high satellite pass total during the past 12 months.

• Column 6 is the pass total (i.e., all satellites) during the past 12 months.

• Column 7 is the LEO NP total during the past 12 months.

• Column 8 is the LAGEOS NP total during the past 12 months.

• Column 9 is the high satellite NP total during the past 12 months.

• Column 10 is the NP total (i.e., all satellites) during the past 12 months.

• Column 11 is the total tracking minutes (i.e., all satellites) during the past 12 months. This is computed by                the summation of the number of normal points multiplied by its bin size in minutes.

• Column 12 is the average single-shot calibration RMS, in millimeters, during the last quarter.

• Column 13 is the average single-shot Starlette RMS, in millimeters, during the last quarter.

• Column 14 is the average single-shot LAGEOS RMS, in millimeters, during the last quarter.
