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 2.1766.
For long arc computations the Earth Orientation Parameters (EOPs) are fixed
to the values of the final IGS (GPS) combination.

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:

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
    

 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.

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 1.1766, 1a.1766).
        
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 2.1766.0-6)                                                                                
    
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 3.1766.0-6). 
        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.

         clocks for each day of the week. The transformation displayed is the
         sum of a priori and estimated transformations.
         WRMS - RMS weighted by the centres SP3 header accuracy codes.
         STA  - Number of stations in the daily solutions.

Table 3: Daily fit for each satellite and each centre resulting from weighted
         average combination and from long arc orbit dynamics (7-day). The
         first IGL column gives resulting satellite accuracy measures found in
         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.
