COMBINATION STRATEGY:
---------------------

Starting with GPS week 860, the IGS Final orbit combination is done directly
in the ITRF without any alignment to the Bulletin B EOP series.

Each centre satellite clock corrections are first transformed to a common 
reference. One of the following two methods can be used (the REMARKS section of
this report gives which method is used):
[1] For each centre, a clock offset and a drift are estimated with respect to
    the broadcast clock corrections using only non-SA satellites;
[2] A chosen reference centre is aligned to the broadcast clock corrections
    using all satellites. All other centres are then aligned to that reference
    centre. 
The offsets and drifts are used to align each centre satellite clock
corrections to GPS time. Ephemerides and clock corrections are then combined
as weighted averages computed over all centres. Each centre is given a
position weight and a clock weight. The position weights are computed from
each centre's absolute deviation to the unweighted average orbit after the
estimation of a 7-parameter Helmert transformation. The clock weights are
either computed from [1] the absolute deviation of the initial alignment to
broadcast clock for the non-SA satellites, or [2] from the absolute deviation
of centre's aligned clock corrections with respect to the unweighted mean.
Finally, a 7-parameter Helmert transformation and clock offset and drift are
estimated for each centre with respect to the combined solutions and parameters
and RMS of fit reported. All the above estimations are performed using the
L1-norm robust scheme.

  Each centre ephemerides are also evaluated individually and independently from
the orbit combination by using week long arcs. The Earth Orientation Parameters
(EOP) used in this evaluation are those submitted by the respective centres.
The IGS combined orbits/clocks and all centres providing both orbit and clock 
solutions are further evaluated by an independent point positioning (navigation)
program that uses both phase and pseudorange data. This is primarily intended 
for testing clock solution precision as well as the orbit/clock consistency.

 Like the clock solutions broadcast in the navigation message, the combined
satellite clocks are corrected for the periodical relativistic correction (see
e.g. GPS interface Control document ICD-GPS-200, p.73):

                              -2*(X.V)/c  [distance unit],

where X and V are the inertial sv state and velocity vectors and c is the speed
of light. Also for compatibility, no satellite L1/L2 delay calibration should be
applied.


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:

  Analysis Centers, Bulletin Geodesique, 69, pp 200-222.

PRODUCTS GENERATED:
-------------------

The resulting average ephemeris and clocks are output to daily files in SP3
format. The satellite accuracy codes displayed in the header are based on the
weighted RMS for each satellite. Note that each file contains all the
satellites that appear in any of the centre ephemeris files. If a satellite or
centre was excluded from combination, a note in the REMARKS section of this
report will identify the exclusion and the reason.

  The resulting x and y earth rotation parameters (ERP) associated with the IGS
ephemeris files and their rates (xrt, yrt) are computed using a weighted average
of all available centres (as part of the separate SINEX combination since GPS
week 1051; weighted according to the orbit combination before that time). 

  Starting with GPS wk 0894, IGS LOD combinations were implemented in the 
Final IGS solutions.  AC LOD biases with respect to Bulletin A are estimated
using Bulletin A most recent 3 weeks (21 days), i.e. up to 5 days prior to
the last non-predicted day of Bulletin A.  AC LOD biases are removed and the
new AC bias-free LODs are used to compute a weighted IGS LOD which in turn
is integrated into IGS UT1-UTC. The starting UT1-UTC value is chosen as
Bulletin A fifth day prior to its last non-predicted day. Both IGS LOD and 
UT1-UTC values are printed in the IGS Final erp file.



The Final Orbit files generated and uploaded into CDDIS @ NASA/GSFC are:

REMARKS concerning the IGS Orbit Combination:                                  
---------------------------------------------

 1. The centres used in the clock combination are COD, EMR, ESA, GFZ, MIT, and JPL.
    The other centres are excluded because of poorer consistency (GRG), they provide
    broadcast clocks (NGS), or clock corrections are not provided (SIO).  The clock
    information not used is still compared to combination for completeness. The
    value of 999999.999999 microseconds, according to the sp3 format convention,
    signifies that no clock solution is available and therefore must not be used.
    
    In general, if an AC does not contribute to the terrestrial reference frame
    (i.e. the SINEX combination), then any corresponding orbits & clocks contributed
    from that AC should not be included with weight in this combination. This is
    done to ensure a high level of consistency between the TRF and the orbital
    frame. However, there is an exception for the clocks if the AC is the reference
    center. In that case, only the clocks from that AC are included with weight.
    
    Starting 12-Aug-2012 (GPS Week 1701, day 0, MJD 56151), GRG clocks are included
    after changing their procedures to generate estimates in the center-of-figure
    frame instead of the center-of-mass frame. Starting 16-Sep-2012 (GPS Week 1706,
    day 0, MJD 56186) the CODE Analysis Center began submitting two solutions: COD
    (1d SNX with 3d orbital arcs) and COF (1d SNX with 1d orbital arcs). The COD
    clocks and orbits are included for comparison only; the COF solution is
    included with weight, and is the reference clock center.
    

 2. Rapid (IGR) orbits/clocks are included in the combination for statistics only.
    Starting week 1582, a new solution from CNES/GRGS (GRG) is included with
    weight except for the clock and LOD combinations.

 3. The following centre clock solutions, which provide broadcast clock
    corrections, were excluded from the combination but kept in the combination
    statistics:
             -> Centre: NGS 

 4. The following clock solutions were excluded from the combination because they
    were biasing the combined clock solutions (clock shifts/outliers) but were
    kept for the RMS computation.  Duplicate entries can arise due to separate
    combination runs for the 30-s clocks ACs (listed first) and the 5-min clock
    ACs (listed second).

 5. Velocity changes were estimated to alleviate the effects of modeling
    problems, experienced by all centres,in the Long Arc (LA) process.
    
             Velocity changes per day and affected satellites:

 6. Starting 5-Nov-2006 (GPS Week 1400, day 0, MJD 54044) until 16-Apr-2011
    (GPS Week 1631, day 6, MJD 55667) all IGS products, including the IGS
    combined orbits, are based on the IGS realization of the ITRF2005 reference
    frame (IGS05).   For more information see IGSMAIL #5447.  The IGS05 frame
    is also the basis for 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) all IGS products,
    are based on the IGS realization of the ITRF2008 reference frame (IGS08).
    For more information see IGSMAIL #6354.
    

 7. Small rotations were applied to all the AC orbit and ERP values in order
    to align them to the current IGS reference frame. These rotations were
    estimated in the IGS SINEX combination process, performed by the IGS Reference
    Frame Coordinator at the Institut Geographique National (IGN). Starting on
    19-Aug-2012 (GPS Week 1702; mjd=56158), ACs began contributing products based
    on 1d SINEX integrations. As a result, the SINEX combinations are now done
    daily instead of weekly, and the associated daily rotations are applied here
    to the orbits and ERPs.  The estimated 7 transformations, from which only the
    3 rotations are applied to the orbit and ERP values, are:

 8. Starting on 22-Oct-2000 (GPS Week 1085-0; mjd=51839) all IGS clock products
    are based on the new clock combination scheme which uses the clock RINEX
    files as input if available, otherwise SP3 clocks are used. 
    The navigation solution is still based on the SP3 clocks but this will soon
    adopt the clock RINEX files as well.

 9. Starting on 27-Feb-2000 (GPS Week 1051-0; MJD 51601) the IGS final products
    are aligned to the IGS reference frame products (station coordinates and ERPs
    as generated by IGN). For more information see IGSMAIL #2750. Because of this
    change in alignment, Table 2 has been enhanced with one additional line per AC.
    This additional line shows daily X- and Y-rotations, i.e. RX_sp3(ac) and
    RY_sp3(ac), used to align each daily AC orbit to the combined SINEX prior to
    the orbit combination. These a-priori rotations are derived from three sources:
    the daily AC polar motion estimates, XPO(ac) and YPO(ac), provided in their ERP
    files; the combined polar motion values, XPO(cmb) and YPO(cmb), from the SINEX
    combination; along with the AC TRF rotations, RX_snx(ac) and RY(ac), also from
    the SINEX combination: 
    
                      RX_sp3(ac) = YPO(ac) - YPO(cmb) + RX_snx(ac)
                      RY_sp3(ac) = XPO(ac) - XPO(cmb) + RY_snx(ac)
    
    Thus, the total rotation of the individual AC orbits w.r.t. the IGS combined
    orbit is the sum of the values in the two lines of Table 2.
    
    Starting on 19-Aug-2012 (GPS Week 1702; mjd=56158), the AC TRF rotations are
    daily values, instead of weekly ones, based on the combination of daily AC
    SINEX files.

10. 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
    The JPL solution did not use IGS08/igs08.atx until GPS Week 1649, which
    caused their RMS clock residuals to be higher during that period than for
    the other centres; since GPS Week 1632 the JPL solution is excluded from
    the weekly SINEX combination.

    
ORBIT COMBINATION AND EVALUATION STATISTICS:                                    
--------------------------------------------                                    
      
Most combination statistics are with respect to the combined orbits and
consist of five parts. The first, 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 (table 1.1706.a). It also displays the computed satellite
position sigmas for the combined orbits (table 1.1706.b).
The second part, 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 2.1706.[0-6]).
The third part, 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 3.1706.[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. The fourth part, Table 4, is a
weekly summary of the daily precise navigation summaries for centres
providing both orbit and clock solutions.  It contains weekly station RMS
w.r.t. the initial coordinates for the Latitude, Longitude and Height 
components for up to three IGS stations (table 4.1307). The fifth and final
part, Table 5, is similar to Table 4 and contains daily precise navigation
statistics (tables 5.1706.0-6).

In tables 1-3, the most important statistic which is meaningful for intra
centre/satellite analysis is labeled WRMS. It is a weighted RMS where
normalized weights are based on accuracy codes given in the SP3 files, and
should not be affected by downweighted/problem satellites when acknowledged
by individual centres in their SP3 file.

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 IGS column gives resulting satellite accuracy measures found in
         SP3 header. The last IGS column gives the RMS fit of the IGS 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 IGS 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.
