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 26, 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, Feb 26, 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 010219 - 010225 6 3 1868 Komsomolsk-na-Amure, Russia 010215 - 010215 1 - 1884 Riga, Latvia 010219 - 010219 2 1 7080 McDonald Obs., Fort Davis, TX 010220 - 010226 9 9 7090 Yarragadee, Australia 010220 - 010225 9 5 7105 Greenbelt, Maryland 010219 - 010224 7 8 7110 Monument Peak, California 010219 - 010222 6 5 7210 Haleakala Obs., Maui, Hawaii 010221 - 010223 3 4 7237 Changchun, China 010219 - 010225 2 3 7249 Beijing, China 010216 - 010219 1 2 7806 Metsahovi, Finland 010226 - 010226 1 - 7811 Borowiec, Poland 010222 - 010225 4 2 7820 Kunming, China 010219 - 010223 8 9 7824 San Fernando, Spain 010219 - 010226 6 4 7832 Riyad, Saudi Arabia 010219 - 010226 3 5 7835 Grasse, France 010218 - 010222 7 5 7836 Potsdam, Germany 010221 - 010226 4 3 7837 Shanghai Observatory, China 010219 - 010219 1 - 7838 Simosato Observatory, Japan 010225 - 010225 2 1 7839 Graz, Austria 010219 - 010223 8 5 7840 Herstmonceux, United Kingdom 010219 - 010225 12 12 7845 Grasse, France (LLR) 010219 - 010226 - 6 7849 Mount Stromlo, Australia 010219 - 010223 10 7 ------ ------ --- --- TOTAL 010215 - 010226 112 99 ------------------------------------------------------------------------------ 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, Feb 15, 2001 to Sun, Feb 25, 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 23 24 Number of Passes 194/186 181/172 Number of Normal Points 1979/1844 1939/1847 RMS of Fit (mm) 30 32 ----------------------------------------------------------------------- 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. The results for station 1824 (Kiev) are still preliminary because of the fact that it concerns a new station with very few observations yet. Initial analysis of the observations (including the estimation of range biases, timing biases and frequency biases, all on a pass-by-pass basis) has not yielded a clear position solution and pass characteristics yet. A more dedicated analysis is needed. ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
