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, Feb 11, 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, Feb 11, 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 ------------------------------------------------------------------------------ 1868 Komsomolsk-na-Amure, Russia 020204 - 020204 1 1 7080 McDonald Obs., Fort Davis, TX 020206 - 020209 5 10 7090 Yarragadee, Australia 020204 - 020211 21 17 7105 Greenbelt, Maryland 020205 - 020209 10 12 7110 Monument Peak, California 020204 - 020209 13 13 7124 Papeete, Tahiti 020205 - 020209 3 1 7237 Changchun, China 020204 - 020210 6 9 7249 Beijing, China 020204 - 020207 1 2 7501 Hartebeesthoek, SA (MOB-6) 020205 - 020211 6 8 7810 Zimmerwald, Switzerland 020204 - 020205 3 1 7811 Borowiec, Poland 020205 - 020206 - 2 7820 Kunming, China 020204 - 020210 2 6 7824 San Fernando, Spain 020205 - 020211 4 4 7832 Riyad, Saudi Arabia 020204 - 020211 10 5 7835 Grasse, France 020204 - 020211 2 4 7838 Simosato Observatory, Japan 020206 - 020210 1 3 7839 Graz, Austria 020202 - 020211 17 10 7840 Herstmonceux, United Kingdom 020205 - 020210 8 6 7849 Mount Stromlo, Australia 020207 - 020211 11 11 8834 Wettzell, Germany 020204 - 020205 2 3 ------ ------ --- --- TOTAL 020202 - 020211 126 128 ------------------------------------------------------------------------------ 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, Jan 31, 2002 to Sun, Feb 10, 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 24 Number of Passes 186/183 182/177 Number of Normal Points 2006/1939 2187/2108 RMS of Fit (mm) 34 36 ----------------------------------------------------------------------- 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. ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
