COMBINATION STRATEGY:                                                            
---------------------                                                            
                                                                               
Ephemeris are combined as weighted averages computed over all centres.          
Each centre and satellite is given a position weight computed from the centers  
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 2.1616.
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:                                  
---------------------------------------------

 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.

 3. Starting on 01-May-2005 (GPS Week 1321; MJD 53491)[IGSMAIL-5151] 
    BKG, ESA, and CODE will start to refer their GLONASS orbit products 
    to the following satellite antenna offset (SAO) values:
    
      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.
    

 4. The satellite clock values in the combined orbit files are taken from the
    broadcast files. The following gps/glonass time offsets derived from the
    bkg summary files were added to the broadcast clocks.
    
               Day | applied clock offset
               ----+---------------------
                0  |    384.6 ns
                1  |    401.1 ns
                2  |    399.0 ns
                3  |    442.5 ns
                4  |    442.4 ns
                5  |    380.0 ns
                6  |    390.1 ns

 5. The following orbit solutions were excluded from the combination
    because they were biasing the weighted average (generally indicated
    by long arc RMS).

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 1.1616, 1a.1616).
        
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 2.1616.0-6)                                                                                
    
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 3.1616.0-6). 
        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.

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.
         "MD"
         Units: mm.
