SLR Global Performance Report Card

January 1, 1998 through December 31, 1998

In addition to the report card are the following graphs. 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.

Below is the detailed descriptions of each column in the performance report card:

  • 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 segment total during the past 12 months.
  • Column 6 is the average single-shot LAGEOS RMS, in millimeters, during the last quarter.
  • Column 7 is the average LAGEOS normal point RMS, in millimeters, during the last quarter, based on CSR 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 CSR Weekly LAGEOS analysis.
  • Column 9 is the measure of long term bias stability, in millimeter, during the past year. A station must have tracked LAGEOS-1 in at least 8 of the last 12 months for a valid measurement. The long term stability is the standard deviation about the mean of the 15 day LAGEOS-1 range biases from CSR LAGEOS-1 long arc analysis.
  • Column 10 is the average data delivery time, in days, to the data centers, during the last quarter.
  • Column 11 is the CSTG normal point format revision number used within the last quarter.
  • Column 12 is a yes/no answer to the question of whether or not configuration files have been provided to the data centers.

The first entry in the table is for the performance baseline goal. Note: There is no baseline goal for single shot RMS or normal point RMS.

Additional Notes: Blanks in any columns mean either that there was no data or that there was insufficient data. A blank in the last column means that the system has been deactivated with no plans for operations in the foreseeable future. Only stations that have supplied data within the last year are included in the table.
