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, Jun 28, 2004. Questions and comments should be addressed to: R. Noomen Delft University of Technology Faculty of Aerospace Engineering Delft Institute for Earth-Oriented Space Research Kluyverweg 1 2629 HS Delft The Netherlands Telephone: +31-15-2785377 Telefax : +31-15-2785322 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, Jun 28, 2004. 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 ------------------------------------------------------------------------------ 1864 Maidanak, Uzbekistan (site 2) 040619 - 040627 12 3 1893 Kazivili, Crimea, Ukraine 040609 - 040610 2 - 6810 Zimmerwald 846, Switzerland 040621 - 040621 1 - 7080 McDonald Obs., Fort Davis, TX 040622 - 040622 1 - 7090 Yarragadee, Australia 040621 - 040628 11 16 7105 Greenbelt, Maryland 040628 - 040628 2 1 7110 Monument Peak, California 040622 - 040625 13 12 7124 Papeete, Tahiti 040621 - 040623 3 - 7237 Changchun, China 040621 - 040624 2 1 7249 Beijing, China 040622 - 040622 1 - 7355 Urumqi, China (TROS) 040621 - 040622 3 1 7501 Hartebeesthoek, SA (MOB-6) 040621 - 040624 - 10 7810 Zimmerwald 423, Switzerland 040621 - 040627 9 9 7811 Borowiec, Poland 040626 - 040626 1 - 7823 San Fernando, Spain (FTLRS) 040624 - 040626 2 - 7824 San Fernando, Spain 040622 - 040624 4 1 7832 Riyad, Saudi Arabia 040621 - 040628 9 16 7835 Grasse, France 040618 - 040618 1 - 7838 Simosato Observatory, Japan 040622 - 040627 4 - 7839 Graz, Austria 040621 - 040628 9 4 7840 Herstmonceux, United Kingdom 040621 - 040628 17 7 7841 Potsdam, Germany 040621 - 040626 6 3 7845 Grasse, France (LLR) 040621 - 040624 4 - 7941 Matera, Italy (MLRO) 040618 - 040628 23 11 8834 Wettzell, Germany 040621 - 040628 17 10 ------ ------ --- --- TOTAL 040609 - 040628 157 105 ------------------------------------------------------------------------------ B. ANALYSIS RESULTS The analysis is based on two orbit solutions using global quick-look normal points that cover a period of 8 days which are computed simultaneously. This week´s data interval runs from Sat, Jun 19, 2004 to Sun, Jun 27, 2004. The measurement and dynamic models used in this analysis are close to the IERS Standard. The overall model is referred to as QLDACMOD11. The details of this model can be obtained on request. The terrestrial reference frame is provided by the ITRF2000 station coordinates solution (extended with coordinates of new stations, where necessary). The general statistics and results of this week´s analysis are thus: ----------------------------------------------------------------------- Satellite LAGEOS-1 LAGEOS-2 Number of Stations 24 16 Number of Passes 160/156 109/108 Number of Normal Points 1525/1472 1143/1129 Weighted RMS of Fit (mm) 11 12 ----------------------------------------------------------------------- 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. The analysis covered in this report is based on a new set of station coordinates: instead of the solution SSC(DUT)93L05, which was extrapolated over some 10 years beyond the epoch of the latest observations, the current analysis relies on the ITRF2000 solution. Tests performed during the last year show that the rms-of-fit that can be obtained when using ITRF2000 can be reduced to about 2 cm (instead of the 3+ cm which was achieved with the old model, for present-day epochs). Other model modifications are to be expected. We hope to serve the community with this development. 2. As of July 1, a new computation model and analysis strategy are in use: in terms of geometric modeling, models for ocean loading and atmospheric pressure loading have been turned on. The frequency of the solutions for the Earth Orientation Parameters has been increased to once per day (rather than once per 3 days). As a consequence, the arc length has been changed from 10 days to 8 days. Also, the empirical accelerations acting on the spacecraft are estimated twice per arc (i.e. for 4-day periods). To absorb (unmodeled) geocenter motion, 3 coefficients of the gravity field model are estimated: C(1,0), C(1,1) and S(1,1). Finally, the overall weighting scheme for the individual SLR observations is also modified slightly. 3. As of the same date, provisions for handling the dual-wavelength systems 7405 and 7810 properly have been installed. This is done by introducing dummy station ids 6405 and 6810 for the observations taken on 2nd wavelength. The specific analysis results are easily recognizable because the wavelength has been added to the printout of the station name. ”/DGFI3/home/slreport/mbox” complete From: Ron Noomen ******************************************************************************** |
