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, Mar 12, 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, Mar 12, 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 010307 - 010307 1 - 1884 Riga, Latvia 010305 - 010309 6 2 7080 McDonald Obs., Fort Davis, TX 010306 - 010311 4 4 7090 Yarragadee, Australia 010305 - 010312 11 10 7105 Greenbelt, Maryland 010306 - 010312 15 12 7110 Monument Peak, California 010308 - 010308 1 1 7210 Haleakala Obs., Maui, Hawaii 010306 - 010308 3 3 7237 Changchun, China 010307 - 010311 3 3 7249 Beijing, China 010306 - 010309 2 2 7501 Hartebeesthoek, SA (MOB-6) 010307 - 010311 4 4 7806 Metsahovi, Finland 010305 - 010308 5 2 7811 Borowiec, Poland 010306 - 010308 5 1 7820 Kunming, China 010307 - 010307 1 1 7824 San Fernando, Spain 010307 - 010311 - 4 7832 Riyad, Saudi Arabia 010309 - 010310 - 2 7836 Potsdam, Germany 010305 - 010309 5 4 7837 Shanghai Observatory, China 010301 - 010308 6 5 7838 Simosato Observatory, Japan 010305 - 010311 2 6 7839 Graz, Austria 010305 - 010312 3 4 7840 Herstmonceux, United Kingdom 010305 - 010308 5 4 7845 Grasse, France (LLR) 010305 - 010309 2 3 7849 Mount Stromlo, Australia 010308 - 010310 5 5 ------ ------ --- --- TOTAL 010301 - 010312 89 82 ------------------------------------------------------------------------------ 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, Mar 1, 2001 to Sun, Mar 11, 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 20 21 Number of Passes 125/124 114/111 Number of Normal Points 1307/1292 1264/1228 RMS of Fit (mm) 32 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 ******************************************************************************** |
