Description of analysis for period 1992 October 04 - 10
1. SOFTWARE USED: GPSOBS/BAHN5
2. MODELS USED AND PARAMETERS ESTIMATED/FIXED
For a description of models and parameters we are using ==> see IGS-Mail 51
For updates of the models and parameters used =============> see IGS-Mail 114
3. GROUND STATIONS (if being estimated, one position (X,Y,Z) every day):
The following table gives an overview over the ground stations, that have
been included into the GPS-data processing at ESOC. Except where otherwise
noted ("remarks"), corrections are taken from IGS Mail No. 90 - IGS site
information and coordinates,updated version of IERS/IGS Tables in IGS Mail
No. 65 - (Boucher and Altamimi).

A-S testing occurred during "03 Oct 92 0100 UT to 05 Sep 92 1000 UT" and
"10 Oct 92 0100 UT to 12 Oct 92 1000 UT", according to the file
pub/gps/gpstd.txt obtained from tycho.usno.navy.mil. Results for Sunday,
Oct 04, and Saturday, Oct 10, are not included in this submission. The
results for Monday, Oct 05, exclude data from Block-II satellites
acquired when A-S was on.
We continue to de-weight data from GPS27 for this week. Although the figures
in the orbit repeatability and broadcast ephemeris comparison tables seem to
indicate a slightly worsening trend for this satellite, it is still reasonably
well-modelled.
WARNING: No warnings for GPS week 665.
