IGLOS Orbit Combination - Week 1987 (Feb 04, 2018 - Feb 10, 2018)
Contact: acc at igs.org
COMBINATION STRATEGY:
---------------------
Ephemeris are combined as weighted averages computed over all centres.
Each centre and satellite is given a position weight computed from the
center's absolute deviation to the unweighted average orbit after removing
small differences in the reference frames. These weights were applied in a
second iteration to estimate Helmert transformation parameters for each
center. Finally the transformation parameters with respect to the combined
solution and the RMS of the fit are reported in Tables 2.1987.
For long arc computations the Earth Orientation Parameters (EOPs) are fixed
to the values of the final IGS (GPS) combination.
SOFTWARE:
---------
The weighted average software used was originally developed by T. Springer
and G. Beutler in 1993. The GPS long arc orbit analysis software used here for
individual centre ephemeris evaluation was developed by Beutler et al. at the
Astronomical Institute of the University of Bern (AIUB). For more details on
the orbit combination and complete references for both software see:

-------------------
The combined IGL-ephemerides are written to daily files in the SP3-format.
The satellite accuracy codes in the header are based on the weighted rms.
for each satellite. Note, that the result files contain all satellites
that were analysed by at least one center. We refer to the 'REMARKS' section
below, in case a satellite or center was excluded from the combination.
The following naming convention is used for the result files:

REMARKS concerning the IGL Orbit Combination:
---------------------------------------------
Starting 16-Sep-2012 (GPS Week 1706, day 0, MJD 56186) the CODE Analysis Center
began submitting two solutions: COD (3d SNX with 3d orbital arcs) and COF (1d
SNX with 1d orbital arcs). The COF clocks and orbits are included for
comparison only; the COD solution is included with weight.
1. Broadcast (brd) orbits and clocks are included in the combination for
statistics only.
2. Having only a few satellites the mcc orbits are included in the combination
for statistics only. The grg orbits are introduced for the first time
starting 02-Jan-2011 (GPS Week 1617) but only for statistics until
22-May-2011 (GPS Week 1637). The bkg orbits were no longer included after
21-May 2011 (GPS Week 1636). The emx orbits are introduced with full weight
for the first time starting 11-Sep-2011 (GPS Week 1653).
3. From 01-May-2005 (GPS Week 1321; MJD 53491) [IGSMAIL-5151] until 4-Nov-2006
BKG, ESA, and CODE referred their GLONASS orbit products to the following
satellite antenna offset (SAO) values (expressed in the spacecraft body
frame):
X/Y/Z = 0.000/0.000/0.000 meter for GLONASS and
X/Y/Z = -0.545/0.000/0.000 meter for GLONASS-M SVs.
Starting 5-Nov-2006 (GPS Week 1400, day 0, MJD 54044) until 16-Apr-2011
(GPS Week 1631, day 6, MJD 55667) the absolute antenna model is introduced
(IGSMAIL #5438). The antenna phase center offsets and phase center variations
are given in the file:
ftp://igs.org/igscb/station/general/igs05.atx
These antenna calibrations are also used in the homogeneously reprocessed IGS
products from GPS Weeks 730 to 1459 (1994-2007); see IGSMAIL #6136.
Starting 17-Apr-2011 (GPS Week 1632, day 0, MJD 55668) the absolute antenna
model is updated (IGSMAIL #6255 & #6374) as given in the file:
ftp://igs.org/igscb/station/general/igs08.atx
Starting 29-Jan-2017 (GPS Week 1934, day 0, MJD 57782) the absolute antenna
model file has been updated to igs14.atx to be consistent with IGS14.
See IGSMAIL #7399 for more information
ftp://igs.org/pub/station/general/igs14.atx
4. The satellite clock values in the combined orbit files are taken from the
broadcast files. The following gps/glonass time offsets were added to the
broadcast clocks. Before GPS Week 1637, the time offsets were derived
from the bkg summary files; starting Week 1637 the offsets are derived
from the gfz summary files.
Day | applied clock offset
----+---------------------
0 | 9.9 ns
1 | 12.7 ns
2 | -17.3 ns
3 | 5.1 ns
4 | -10.5 ns
5 | 4.8 ns
6 | 7.7 ns
5. The following orbit solutions were excluded from the combination
because they were biasing the weighted average (generally indicated
by long arc RMS).

ORBIT COMBINATION AND EVALUATION STATISTICS:
--------------------------------------------
Table 1 summarizes all statistics for the week. It contains means and standard
deviations over the week of satellite ephemeris and clock correction
transformation parameters for each centre (Tables 1.1987, 1a.1987).
Table 2 contains the complete ephemeris and clock correction transformation
parameters (includes both the apriori and a posteriori values) for each
centre and each day (Tables 2.1987.0-6)
Table 3 contains two types of daily RMS for each satellite and centre, along
with the computed satellite position sigmas for the combined orbits
(tables 3.1987.0-6).
The first type of satellite RMS is based on orbit combination and the
second RMS type is a result of the 7-day arc evaluation of each centre
ephemerides.

SP3 header. The last IGL column gives the RMS fit of the IGL orbit
when processed through the 7-day arc evaluation.
"E" stands for eclipsing satellites (earth).
"M" stands for eclipsing satellites (moon).
"X" stands for excluded from the statistics but included in IGL orbit.
"T" stands for Total long arc orbit RMS for all satellites.
"NE" stands for long arc orbit RMS for Non-Eclipsing satellites only.
"MEDI" stands for median of the centre's satellite RMS.
"MD"
Units: mm.
