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, Jan 29, 2001. Questions and comments should be addressed to: K.F.

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, Jan 29,2001. 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 ------------------------------------------------------------------------------ 1824 Kiev, Ukraine 010123 - 010124 5 4 1873 Simeiz, Crimea, Ukraine 010126 - 010126 1 1 1884 Riga, Latvia 010123 - 010123 1 2 7080 McDonald Obs., Fort Davis, TX 010122 - 010127 7 6 7090 Yarragadee, Australia 010123 - 010129 10 7 7105 Greenbelt, Maryland 010122 - 010129 18 13 7124 Papeete, Tahiti 010124 - 010126 2 - 7210 Haleakala Obs., Maui, Hawaii 010123 - 010126 3 2 7249 Beijing, China 010126 - 010129 6 5 7501 Hartebeesthoek, SA (MOB-6) 010122 - 010127 3 - 7811 Borowiec, Poland 010124 - 010127 6 3 7820 Kunming, China 010121 - 010127 3 6 7824 San Fernando, Spain 010122 - 010123 - 2 7832 Riyad, Saudi Arabia 010122 - 010128 3 4 7835 Grasse, France 010125 - 010125 1 - 7836 Potsdam, Germany 010123 - 010127 3 3 7837 Shanghai Observatory, China 010126 - 010129 2 1 7838 Simosato Observatory, Japan 010123 - 010128 2 3 7839 Graz, Austria 010123 - 010123 - 1 7840 Herstmonceux, United Kingdom 010124 - 010126 6 4 7845 Grasse, France (LLR) 010129 - 010129 - 1 7849 Mount Stromlo, Australia 010122 - 010129 6 5 ------ ------ --- --- TOTAL 010121 - 010129 88 73 ------------------------------------------------------------------------------ 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 18, 2001 to Sun, Jan 28, 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 24 21 Number of Passes 139/134 114/110 Number of Normal Points 1359/1309 1168/1114 RMS of Fit (mm) 38 34 ----------------------------------------------------------------------- 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. Because of a software problem the report that was disseminated last week contained no pass statistics, and incorrect general statistics. This report replaces the previous one. ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
