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 11, 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 12, 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 ------------------------------------------------------------------------------ 1893 Kazivili, Crimea, Ukraine 001201 - 001202 1 1 7080 McDonald Obs., Fort Davis, TX 001205 - 001211 11 10 7090 Yarragadee, Australia 001204 - 001211 10 13 7105 Greenbelt, Maryland 001204 - 001211 10 10 7110 Monument Peak, California 001204 - 001211 10 9 7124 Papeete, Tahiti 001205 - 001211 4 3 7210 Haleakala Obs., Maui, Hawaii 001206 - 001208 3 - 7231 Wuhan, China (new) 001205 - 001205 2 1 7237 Changchun, China 001210 - 001210 2 - 7249 Beijing, China 001204 - 001210 5 4 7339 Tateyama, Japan 001204 - 001208 17 16 7810 Zimmerwald, Switzerland 001205 - 001206 2 1 7820 Kunming, China 001204 - 001210 8 10 7824 San Fernando, Spain 001208 - 001210 4 5 7835 Grasse, France 991220 - 001211 7 7 7836 Potsdam, Germany 001201 - 001209 4 2 7837 Shanghai Observatory, China 001205 - 001208 6 5 7838 Simosato Observatory, Japan 001204 - 001210 7 8 7840 Herstmonceux, United Kingdom 001204 - 001211 3 3 7845 Grasse, France (LLR) 001204 - 001204 1 1 7849 Mount Stromlo, Australia 001203 - 001211 25 20 8834 Wettzell, Germany 991222 - 001211 3 3 ------ ------ --- --- TOTAL 991220 - 001211 145 132 ------------------------------------------------------------------------------ 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, Nov 30, 2000, to Sat, Dec 9, 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 23 Number of Passes 182/180 162/159 Number of Normal Points 1715/1676 1735/1688 RMS of Fit (mm) 31 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. 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. 2. This week´s batch of data contained a number of passes taken during the month of December of 1999: SAT STAT START-TIME STOP-TIME # ---------------------------------------------------- 9207002 7835 991220 184323 - 991220 190300 11 7603901 7835 991220 190653 - 991220 193222 14 7603901 7835 991220 222319 - 991220 223640 8 9207002 7835 991220 225105 - 991220 233254 19 9207002 7835 991221 131517 - 991221 132707 7 7603901 7835 991221 142946 - 991221 150036 17 9207002 8834 991222 111154 - 991222 114419 18 7603901 8834 991222 130715 - 991222 133011 13 A simple confrontation with the orbit solutions obtained a year ago showed no significant data problems for any of these passes. ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
