Subject: Geodetic Survey Division (GSD), SMRSS, EMR analysis results
for the GPS week # 664 (Sep 29-Oct 02, 1992)

Geodetic Survey Division (GSD), Surveys Mapping & Remote Sensing Sector
(SMRS), Energy Mines and Resources (EMR), 615 Booth Str., Ottawa, K1A 0E3
* on secondment to the Geodetic Survey from the Geophysics Div., Geological
Survey of Canada (GSC), EMR, 1 Observatory cresc., Ottawa, K1A 0Y3
Our analysis utilizes the JPL GIPSY/OASIS II (UNIX) software system
and data from all (up to 7) Canadian stations augmented by up to 10, globally
distributed, core stations (see Table 1 for the list of stations).
Submitted results start with GPS Week # 664 and include only days when
AS was not invoked. This effort is a part of a joint pilot project to test the
so called "Active Control System" in Canada and involves the Geodetic
Survey (GSD), SMRSS, the Geophysics Division and Pacific Geoscience Centre of
the Geological Survey of Canada, all three institutions are part of the
Department of Energy, Mines & Resources (EMR).

SOLUTION CHARACTERISTICS
Reference frame and orientation
Nominally ITRF91 at epoch 1992.5, realized by constraining the
following stations at the IGS coordinates (see IGS message #90):

The remaining stations are considered unknown (with 50 m apriori sigmas).
Orientation is realized through the above coordinates and the fixed DUT1
values from NEOS/IERS (Bull. A).
Constants and models
- no change, see the IGS mess. #101 for details -
Estimation strategies
- no change, see the IGS mess. #101 for details -
ALGO was used as time reference.

OUTLINE OF THE ESTIMATION OF GPS-ORBITS AND EARTH ROTATION PARAMETERS AT THE
ESOC PROCESSING CENTER FOR IGS
J.M.Dow, S.Casotto, J.Feltens, S.Frey, C.Garcia-Martinez, T.Martin-Mur
Description of analysis for period 1992 September 27 - October 03
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
Satellite SV-27 has been included into processing since day 275 (October 1st)
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).
