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, Oct 24, 2005. 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, Oct 24, 2005. 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 ------------------------------------------------------------------------------ 1873 Simeiz, Crimea, Ukraine 051023 - 051023 - 1 6405 Concepcion, Chile (TIGO 847) 051022 - 051024 4 5 6810 Zimmerwald 846, Switzerland 051023 - 051024 2 2 7090 Yarragadee, Australia 051022 - 051023 2 2 7110 Monument Peak, California 051022 - 051022 1 1 7810 Zimmerwald 423, Switzerland 051024 - 051024 1 2 7824 San Fernando, Spain 051021 - 051024 3 2 7825 Mount Stromlo, Australia 051022 - 051023 3 4 7832 Riyad, Saudi Arabia 051022 - 051024 7 5 7838 Simosato Observatory, Japan 051022 - 051022 1 1 7840 Herstmonceux, United Kingdom 051022 - 051023 2 1 7941 Matera, Italy (MLRO 532) 051023 - 051023 - 1 8834 Wettzell, Germany 051022 - 051024 2 2 ------ ------ --- --- TOTAL 051021 - 051024 28 29 ------------------------------------------------------------------------------ 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 Sun, Oct 16, 2005 to Mon, Oct 24, 2005. 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 23 20 Number of Passes 175/173 149/148 Number of Normal Points 1763/1753 1648/1635 Weighted RMS of Fit (mm) 15 14 ----------------------------------------------------------------------- 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.

EARTH ROTATION PARAMETER SOLUTIONS FOR IERS The following solutions for the polar motion and the UT1-UTC time difference were also obtained in the 10-day data arc analysis described in the previous section. Only solutions submitted to IERS are presented here. -------------------------------------------------------------- DATE X Y UT1-UTC (YYMMDD.D) (MAS) (MAS) (MS) -------------------------------------------------------------- 051017.0 69.2 +/- 0.1 408.6 +/- 0.1 -32670.25 +/- 0.01 051018.0 70.3 +/- 0.1 408.0 +/- 0.1 -32671.41 +/- 0.02 051019.0 71.1 +/- 0.1 408.2 +/- 0.1 -32672.39 +/- 0.03 051020.0 71.0 +/- 0.1 407.7 +/- 0.1 -32673.11 +/- 0.04 051021.0 70.4 +/- 0.1 406.7 +/- 0.1 -32673.62 +/- 0.04 051022.0 70.6 +/- 0.2 406.3 +/- 0.1 -32673.89 +/- 0.05 051023.0 70.7 +/- 0.1 406.3 +/- 0.1 -32674.18 +/- 0.06 -------------------------------------------------------------- D. 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, 2003, 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. 4. As of July 7, 2004, similar provisions for handling the dual-wavelength syste 7941 properly have been installed. This is done by introducing a dummy station id 6941 for the observations taken on 2nd wavelength. From: Ron Noomen ******************************************************************************** |
