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, Sep 30, 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, Sep 30, 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 ------------------------------------------------------------------------------ 1831 Lviv, Ukraine 020507 - 020905 11 3 1863 Maidanak, Uzbekistan (site 1) 020920 - 020922 2 - 1864 Maidanak, Uzbekistan (site 2) 020919 - 020922 3 2 1884 Riga, Latvia 020929 - 020929 2 1 1893 Kazivili, Crimea, Ukraine 020927 - 020927 1 - 7080 McDonald Obs., Fort Davis, TX 020923 - 020930 17 15 7090 Yarragadee, Australia 020924 - 020930 6 11 7105 Greenbelt, Maryland 020924 - 020930 - 8 7110 Monument Peak, California 020923 - 020928 16 10 7124 Papeete, Tahiti 020925 - 020927 2 2 7210 Haleakala Obs., Maui, Hawaii 020923 - 020929 7 8 7237 Changchun, China 020903 - 020929 15 7 7249 Beijing, China 020923 - 020928 2 1 7403 Arequipa, Peru (TLRS-3) 020924 - 020930 - 5 7405 Concepcion, Chile (TIGO) 020926 - 020929 1 3 7501 Hartebeesthoek, SA (MOB-6) 020925 - 020925 - 1 7806 Metsahovi, Finland 020923 - 020929 6 2 7824 San Fernando, Spain 020923 - 020930 9 7 7832 Riyad, Saudi Arabia 020923 - 020930 6 3 7835 Grasse, France 020926 - 020928 3 2 7836 Potsdam, Germany 020930 - 020930 1 - 7837 Shanghai Observatory, China 020923 - 020923 1 - 7838 Simosato Observatory, Japan 020924 - 020924 2 1 7839 Graz, Austria 020925 - 020930 8 5 7840 Herstmonceux, United Kingdom 020923 - 020930 20 15 7849 Mount Stromlo, Australia 020923 - 020930 3 1 8834 Wettzell, Germany 020928 - 020930 5 5 ------ ------ --- --- TOTAL 020507 - 020930 149 118 ------------------------------------------------------------------------------ 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, Sep 19, 2002 to Sun, Sep 29, 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 24 23 Number of Passes 188/187 156/155 Number of Normal Points 1953/1928 1649/1611 RMS of Fit (mm) 31 31 ----------------------------------------------------------------------- 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. This week´s batch of QL data included observations of a new SLR station in Lviv, Ukraine (1831, DOMES number 12368S001). Further information can be obtained from the station log sheet at the ILRS web pages. ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
