SLR Global Performance Report Card

March 1, 2012 through February 28, 2013

The performance report card is divided into three tables for readability. Table 1 contains performance parameters based on data volume, on-site processing statistics and operational compliance issues. Table 1 L contains information about Lunar Laser Ranging during the past year. Table 2 contains performance parameters based on various Analysis Centers' rapid orbital analysis results.

Below are the detailed descriptions of each column in Table 1 plots of the columns are linked in this description and in Table 1:

• 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.

The first entry in each table is for the performance baseline goal. Note: There are no baseline goals for NP data quantities, single shot RMS's.

Additional Notes: Blanks in any columns implies either that there was no data or that there was insufficient data. Only stations that have supplied data within the last year are included in the table. The table is sorted in descending order by total passes.

Below are the detailed descriptions of each column in Table 2:

• the first column is the station location name.
• the second column is the monument marker number.
• following columns are in grouped by analysis center with four columns for each
• the first AC column is the average LAGEOS normal point RMS, in millimeters, during the last quarter
• the second AC column is the measure of short term bias stability, in millimeters, during the last quarter. The short term stability is computed as the standard deviation about the mean of the pass-by-pass range biases (minimum number of passes in quarter is 10)
• the third AC column is the measure of long term bias stability, in millimeters, during the past year. The long term stability is the standard deviation of the monthly range bias estimates. A station must have tracked LAGEOS (1,2) in at least 8 of the last 12 months in order to compute this metric.
• the fourth AC column is the percentage of LAGEOS normal points that were accepted in the analysis.

The first entry in each table is for the performance baseline goal.

Additional Notes: Blanks in any columns implies either that there was no data or that there was insufficient data. Only stations that have supplied data within the last year are included in the table. The table is sorted in descending order by total data volume.
