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, May 28, 2001. 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, May 28, 2001. 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 ------------------------------------------------------------------------------ 1873 Simeiz, Crimea, Ukraine 010526 - 010527 2 - 1884 Riga, Latvia 010522 - 010522 1 - 1893 Kazivili, Crimea, Ukraine 010523 - 010524 3 - 7080 McDonald Obs., Fort Davis, TX 010522 - 010528 11 11 7090 Yarragadee, Australia 010521 - 010528 10 10 7105 Greenbelt, Maryland 010523 - 010527 7 5 7110 Monument Peak, California 010521 - 010527 11 5 7124 Papeete, Tahiti 010516 - 010524 3 3 7210 Haleakala Obs., Maui, Hawaii 010522 - 010525 4 - 7237 Changchun, China 010522 - 010525 2 - 7249 Beijing, China 010524 - 010528 6 - 7339 Tateyama, Japan 010525 - 010525 2 1 7355 Urumqi, China (TROS) 010518 - 010527 9 1 7403 Arequipa, Peru (TLRS-3) 010521 - 010526 8 11 7501 Hartebeesthoek, SA (MOB-6) 010521 - 010521 2 2 7806 Metsahovi, Finland 010522 - 010522 1 - 7810 Zimmerwald, Switzerland 010521 - 010528 13 14 7811 Borowiec, Poland 010521 - 010526 8 - 7824 San Fernando, Spain 010523 - 010528 8 - 7832 Riyad, Saudi Arabia 010527 - 010528 2 2 7835 Grasse, France 010522 - 010528 10 2 7836 Potsdam, Germany 010522 - 010526 8 1 7837 Shanghai Observatory, China 010523 - 010523 1 - 7838 Simosato Observatory, Japan 010524 - 010527 3 - 7839 Graz, Austria 010519 - 010522 3 1 7840 Herstmonceux, United Kingdom 010521 - 010528 18 14 7845 Grasse, France (LLR) 010525 - 010528 1 2 7849 Mount Stromlo, Australia 010521 - 010524 8 6 8834 Wettzell, Germany 010521 - 010526 15 12 ------ ------ --- --- TOTAL 010516 - 010528 180 103 ------------------------------------------------------------------------------ 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, May 17, 2001 to Sun, May 27, 2001. 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 28 17 Number of Passes 251/241 142/141 Number of Normal Points 2561/2391 1596/1581 RMS of Fit (mm) 31 30 ----------------------------------------------------------------------- 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 ******************************************************************************** |
