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, Dec 18, 2000. 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, received by the Quick-Look Data Analysis Center (QLDAC) on Tue, Dec 19, 2000. All data were obtained through 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 ------------------------------------------------------------------------------ 1864 Maidanak, Uzbekistan (site 2) 001210 - 001217 1 2 1884 Riga, Latvia 001212 - 001212 1 - 7080 McDonald Obs., Fort Davis, TX 001213 - 001217 5 3 7090 Yarragadee, Australia 001211 - 001218 9 6 7105 Greenbelt, Maryland 001212 - 001218 8 8 7110 Monument Peak, California 001211 - 001218 17 17 7237 Changchun, China 001211 - 001215 10 4 7249 Beijing, China 001211 - 001215 4 4 7335 Kashima, Japan 001211 - 001215 11 11 7339 Tateyama, Japan 001211 - 001215 11 9 7501 Hartebeesthoek, SA (MOB-6) 001212 - 001217 5 2 7820 Kunming, China 001211 - 001217 6 10 7824 San Fernando, Spain 001212 - 001218 7 3 7835 Grasse, France 001211 - 001217 10 9 7836 Potsdam, Germany 001213 - 001216 5 3 7837 Shanghai Observatory, China 001213 - 001214 2 1 7838 Simosato Observatory, Japan 001208 - 001216 12 10 7839 Graz, Austria 001211 - 001217 5 7 7840 Herstmonceux, United Kingdom 001213 - 001216 9 6 7845 Grasse, France (LLR) 001213 - 001217 2 4 7849 Mount Stromlo, Australia 001211 - 001217 9 11 8834 Wettzell, Germany 001211 - 001218 2 5 ------ ------ --- --- TOTAL 001208 - 001218 151 135 ------------------------------------------------------------------------------ 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, Dec 7, 2000, to Sat, Dec 16, 2000. 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 22 Number of Passes 210/207 188/187 Number of Normal Points 1898/1850 2001/1968 RMS of Fit (mm) 39 40 ----------------------------------------------------------------------- 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. Bias uncertainties are 3 sigma values. -------------------------------------------------------------------------------- Date Time Sat. Obs.

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 5 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. Users of this report are invited to give suggestions for further improvements. ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
