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 Tue, Apr 4, 2006. 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 Tue, Apr 4, 2006. 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) 060403 - 060404 2 - 1873 Simeiz, Crimea, Ukraine 060404 - 060404 1 - 6810 Zimmerwald 846, Switzerland 060403 - 060404 4 4 7090 Yarragadee, Australia 060403 - 060404 5 4 7124 Papeete, Tahiti 060403 - 060403 1 1 7406 San Juan, Argentina 060404 - 060405 3 5 7501 Hartebeesthoek, SA (MOB-6) 060403 - 060404 4 3 7810 Zimmerwald 423, Switzerland 060403 - 060404 3 4 7824 San Fernando, Spain 060404 - 060404 1 - 7825 Mount Stromlo, Australia 060403 - 060404 5 4 7832 Riyad, Saudi Arabia 060403 - 060404 4 2 7838 Simosato Observatory, Japan 060403 - 060403 1 - 7839 Graz, Austria 060331 - 060404 5 5 7841 Potsdam, Germany 060404 - 060405 3 1 7941 Matera, Italy (MLRO 532) 060403 - 060405 8 3 ------ ------ --- --- TOTAL 060331 - 060405 50 36 ------------------------------------------------------------------------------ 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 Mon, Mar 27, 2006 to Tue, Apr 4, 2006. 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 26 17 Number of Passes 173/173 103/103 Number of Normal Points 1690/1679 1204/1197 Weighted RMS of Fit (mm) 18 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.
