The report consists of (A) a pass summary, (B) an overview of the analysis results, detailed statistics of the analysed measurements, and an accumulative pass overview and (C) the earth rotation parameter solutions submitted to IERS. The report is based on all quick-look data as received until Mon, Aug 5, 2002. Questions and comments should be addressed to: K.F.

PASS SUMMARY The table below gives an overview of the ranging data both on LAGEOS-1 and LAGEOS-2, as received by the Quick-Look Data Analysis Center (QLDAC) on Mon, Aug 5, 2002. All data were obtained through the NASA Crustal Dynamics Data Information system (CDDIS) and the Eurolas Data Center (EDC) in Germany. The data are unscreened and may span more than a week due to late reporting by the stations. ------------------------------------------------------------------------------ Station System/Location Period No. of Passes ID LAGEOS-1 LAGEOS-2 ------------------------------------------------------------------------------ 1884 Riga, Latvia 020729 - 020805 5 - 7080 McDonald Obs., Fort Davis, TX 020730 - 020805 8 5 7090 Yarragadee, Australia 020730 - 020805 9 7 7105 Greenbelt, Maryland 020729 - 020805 13 4 7110 Monument Peak, California 020729 - 020804 17 3 7124 Papeete, Tahiti 020730 - 020802 3 2 7210 Haleakala Obs., Maui, Hawaii 020731 - 020804 7 2 7237 Changchun, China 020803 - 020804 3 - 7403 Arequipa, Peru (TLRS-3) 020731 - 020802 2 2 7405 Concepcion, Chile (TIGO) 020804 - 020804 - 1 7501 Hartebeesthoek, SA (MOB-6) 020730 - 020803 8 9 7810 Zimmerwald, Switzerland 020729 - 020805 12 10 7824 San Fernando, Spain 020727 - 020805 9 - 7832 Riyad, Saudi Arabia 020729 - 020805 15 11 7835 Grasse, France 020802 - 020804 2 - 7836 Potsdam, Germany 020728 - 020803 11 - 7837 Shanghai Observatory, China 020729 - 020805 15 2 7838 Simosato Observatory, Japan 020731 - 020803 5 1 7839 Graz, Austria 020729 - 020803 7 5 7840 Herstmonceux, United Kingdom 020729 - 020805 12 6 7845 Grasse, France (LLR) 020801 - 020801 1 - 7848 Ajaccio, Corsica (FTLRS) 020804 - 020804 1 - 8834 Wettzell, Germany 020729 - 020805 7 7 ------ ------ --- --- TOTAL 020727 - 020805 172 77 ------------------------------------------------------------------------------ B. ANALYSIS RESULTS The analysis is based on two orbit solutions using global quick-look normal points that cover a period of 10 days which are computed simultaneously. This week´s data interval runs from Thu, Jul 25, 2002 to Sun, Aug 4, 2002. The measurement and dynamic models used in this analysis are close to the IERS Standard. The overall model is referred to as QLDACMOD9. The details of this model can be obtained on request. The terrestrial reference frame is provided by a special version of the SSC(DUT) 93L05 station coordinates solution. The general statistics and results of this week´s analysis are thus: ----------------------------------------------------------------------- Satellite LAGEOS-1 LAGEOS-2 Number of Stations 25 17 Number of Passes 237/236 106/105 Number of Normal Points 2418/2383 1022/1008 RMS of Fit (mm) 31 38 ----------------------------------------------------------------------- Residual statistics per station. The header line for each station shows the station id, its name, whether the position is solved for or not and the measurement accuracy in mm. Rejected observations are not used for the calculation of the rms-of-fit, the biases or the scatter. The latter holds w.r.t. the residual trend line described by the bias estimates. Uncertainties are 3-sigma values. -------------------------------------------------------------------------------- Date Time Sat. Obs.

COMMENTS 1. This is a QLDAC analysis report in a new style. Although our old report served quite well for observation campaigns, we have received many requests to adjust our report to the current situation (i.e. a permanent global SLR network with few mobile systems), and to spend more attention to the quality of the data taken by the global network. The most important element of the report is the table with statistics for each individual data pass. Although the numbers will speak for themselves, we must give a warning here that some of you may be disappointed to see that their station appears to be suffering from a data problem. However, we are using a model for station positions that is already 7 years old, and which may be responsible for errors in the station position in the order of 1-5 cm. We intend to introduce a new coordinates solution in the course of this millennium. Readers of this report are invited to provide us suggestions for further improvements. 2. The LAGEOS-1 passes taken by Wettzell (8834), according to the data records taken on June 16, 0h 7m 11sec GMT, proves to be actually taken on June 17 (same epoch in the day). ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
