WEEK 40, 2000


This is a weekly report, presenting the results of a continuing analysis of the
most recent global LAGEOS-1 and LAGEOS-2 quick-look laser ranging data. 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 2, 2000.

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,
Oct 3, 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.

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, Sep 21, 2000, to Sat, Sep 30, 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 32 21
Number of Passes 232/228 144/144
Number of Normal Points 2416/2341 1662/1653
RMS of Fit (mm) 49 52
-----------------------------------------------------------------------


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.

C. 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.

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 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.
