SLR Global Performance Report Card

July 1, 2001 through June 30, 2002

In addition to the report card are the following graphs. (Performance Graphs in GIF format (compressed)). Note: Click on the hyperlinks below to go the appropriate graph. Please don't forget to change your printer page format to landscape if you want to print the charts.

The performance report card is divided into two tables for readability. Table 1 contains a list of performance parameters based on data volume, on-site processing statistics and operational compliance issues. Table 2 contains a list of performance parameters based on orbital analysis results from CSR and MCC weekly LAGEOS reports.

Below are the detailed descriptions of each column 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 tracking minutes total (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 ERS RMS, in millimeters, during the last quarter.
  • Column 14 is the average single-shot LAGEOS RMS, in millimeters, during the last quarter.
  • Column 15 is the median data latency, in hours, to the data centers, during the last quarter.
  • Column 16 is the ILRS normal point format revision number used within the last quarter.
  • Column 17 is a yes/no answer to the question of whether or not a site log has been provided to the central bureau. Site logs will be a replacement for the configuration files.

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, and normal point RMS.

Additional Notes: Blanks in any columns mean 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.

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

  • Column 1 is the station location name.
  • Column 2 is the monument marker number.
  • Column 3 is the average LAGEOS normal point RMS, in millimeters, during the last quarter, based on CSR Weekly LAGEOS analysis.
  • Column 4 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 from the CSR Weekly LAGEOS analysis.
  • Column 5 is the measure of long term bias stability, in millimeter, during the past year. The long term stability is the standard deviation of the monthly range bias estimates from the CSR Weekly LAGEOS analysis. A station must have tracked LAGEOS (1,2) in at least 8 of the last 12 months in order to compute this metric.
  • Column 6 is the percentage of LAGEOS normal points that were accepted in CSR weekly LAGEOS analysis.
  • Column 7 is the average LAGEOS normal point RMS, in millimeters, during the last quarter, based on MCC Weekly LAGEOS analysis.
  • Column 8 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 from the MCC Weekly LAGEOS analysis.
  • Column 9 is the measure of long term bias stability, in millimeter, during the past year. The long term stability is the standard deviation of the monthly range bias estimates from the MCC Weekly LAGEOS analysis. A station must have tracked LAGEOS (1,2) in at least 8 of the last 12 months in order to compute this metric.
  • Column 10 is the percentage of LAGEOS normal points that were accepted in MCC weekly LAGEOS analysis.
