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 26, 2002. Questions and comments should be addressed to: K.F. Wakker Delft University of Technology Faculty of Aerospace Engineering Delft Institute for Earth-Oriented Space Research Kluyverweg 1 NL-2629 HS Delft The Netherlands Telephone: +31-(0)15-2782065/2785377 Telefax : +31-(0)15-2785322 E-mail : ron.noomen@deos.tudelft.nl A. 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 26, 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 020819 - 020823 6 - 7080 McDonald Obs., Fort Davis, TX 020820 - 020826 6 10 7090 Yarragadee, Australia 020819 - 020826 12 11 7105 Greenbelt, Maryland 020819 - 020826 7 2 7110 Monument Peak, California 020819 - 020826 20 12 7124 Papeete, Tahiti 020815 - 020822 2 3 7210 Haleakala Obs., Maui, Hawaii 020819 - 020825 6 4 7237 Changchun, China 020819 - 020825 4 - 7403 Arequipa, Peru (TLRS-3) 020820 - 020823 1 1 7501 Hartebeesthoek, SA (MOB-6) 020820 - 020823 7 8 7806 Metsahovi, Finland 020821 - 020821 1 - 7810 Zimmerwald, Switzerland 020819 - 020825 6 5 7824 San Fernando, Spain 020815 - 020821 5 - 7832 Riyad, Saudi Arabia 020819 - 020826 10 13 7835 Grasse, France 020818 - 020824 6 1 7836 Potsdam, Germany 020820 - 020824 9 1 7837 Shanghai Observatory, China 020822 - 020822 - 1 7838 Simosato Observatory, Japan 020819 - 020822 4 - 7839 Graz, Austria 020819 - 020826 17 6 7840 Herstmonceux, United Kingdom 020817 - 020826 20 12 7845 Grasse, France (LLR) 020820 - 020823 2 - 7848 Ajaccio, Corsica (FTLRS) 020822 - 020823 2 - 7849 Mount Stromlo, Australia 020819 - 020825 6 5 8834 Wettzell, Germany 020819 - 020826 5 6 ------ ------ --- --- TOTAL 020815 - 020826 164 101 ------------------------------------------------------------------------------ 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, Aug 15, 2002 to Sun, Aug 25, 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 23 18 Number of Passes 234/233 126/125 Number of Normal Points 2460/2385 1300/1265 RMS of Fit (mm) 32 41 ----------------------------------------------------------------------- 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.

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 table with residual statistics shows a large number of rejected observations for some of the passes taken by Zimmerwald (7810). This is purely artificial, and due to the fact that dual-wavelength observations were submitted whereas the QLDAC analysis software has not been updated to accomodate this yet. We apologize for any inconvenience. ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
