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, Jul 8, 2002. 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, Jul 8, 2002. 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 020703 - 020705 4 - 1863 Maidanak, Uzbekistan (site 1) 020628 - 020702 4 1 1873 Simeiz, Crimea, Ukraine 020706 - 020706 1 - 1893 Kazivili, Crimea, Ukraine 020702 - 020704 3 - 7080 McDonald Obs., Fort Davis, TX 020704 - 020706 2 1 7090 Yarragadee, Australia 020702 - 020708 13 10 7105 Greenbelt, Maryland 020702 - 020706 7 2 7110 Monument Peak, California 020701 - 020708 12 1 7210 Haleakala Obs., Maui, Hawaii 020701 - 020704 1 1 7237 Changchun, China 020701 - 020707 8 - 7403 Arequipa, Peru (TLRS-3) 020702 - 020708 4 3 7405 Concepcion, Chile (TIGO) 020701 - 020707 9 8 7501 Hartebeesthoek, SA (MOB-6) 020701 - 020708 22 15 7810 Zimmerwald, Switzerland 020617 - 020708 10 9 7811 Borowiec, Poland 020706 - 020707 2 - 7824 San Fernando, Spain 020420 - 020708 14 - 7832 Riyad, Saudi Arabia 020701 - 020708 6 15 7835 Grasse, France 020703 - 020707 6 2 7836 Potsdam, Germany 020704 - 020707 5 - 7837 Shanghai Observatory, China 020705 - 020705 1 - 7839 Graz, Austria 020701 - 020708 14 8 7840 Herstmonceux, United Kingdom 020704 - 020706 2 2 7845 Grasse, France (LLR) 020702 - 020705 3 - 7848 Ajaccio, Corsica (FTLRS) 020627 - 020705 5 - 7849 Mount Stromlo, Australia 020702 - 020708 7 6 8834 Wettzell, Germany 020701 - 020708 3 4 ------ ------ --- --- TOTAL 020420 - 020708 168 88 ------------------------------------------------------------------------------ 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, Jun 27, 2002 to Sun, Jul 7, 2002. 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 27 18 Number of Passes 244/239 126/125 Number of Normal Points 2497/2433 1380/1339 RMS of Fit (mm) 42 37 ----------------------------------------------------------------------- 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 LAGEOS-1 passes taken by Wettzell (8834), according to the data records taken on June 16, 0h 7m 11sec GMT, proves to be actually taken on June 17 (same epoch in the day). ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
