OUTLINE OF THE ESTIMATION OF GPS-ORBITS AND EARTH ROTATION PARAMETERS
AT THE ESOC PROCESSING CENTRE FOR IGS
J.M.Dow, T.Martin-Mur, J.Feltens, C.Garcia-Martinez
Description of analysis for period 1993 Dec 26 - Jan 01
(week 0729)
1. SOFTWARE USED: GPSOBS/BAHN-Version 5
2. MODELS USED AND PARAMETERS ESTIMATED/FIXED:
For a description of models and parameters used ==> see IGS - Mail 51
For updates of the models and parameters used ==> see IGS - Mail 114 and
see IGS - Rep. 224,277
- From this week we will use the ITRF92 station coordinates from
IGS Mails 421 and 430. Antenna heights were obtained from the
file localtie.tab from sideshow.jpl.nasa.gov /igscb/station/tie.
We are now fixing the coordinates of the 13 stations included in the
IGS Mail 430.
We have run the GPS week 0729 with the old and the new coordinates
and the statistics for the difference between the erps calculated
with the new coordinates and the erps calculated with the old are:
erp mean diff. (itrf92 - itrf91) standard deviation
---- ---------------------------- ------------------
xp -0.75 mas 0.08 mas
yp -0.12 mas 0.09 mas
lodr 0.040 ms/day 0.041 ms/day
- We are also now able to provide the correlations between erp
parameters and they will be included in the erp file.
3. REMARKS: none
4. GROUND STATIONS: Altamimi and Boucher, IGS Mails 421 and 430,
ITRF92 at 1994.0 and localtie.tab.
