3) Combination Strategy:
========================
The AC solutions are processed using the following procedure:
3-1) The AC solutions are checked/corrected for possible format problems,
station names inconsistencies, etc...
3-2) The AC solutions are unconstrained according to the information provided
in the SOLUTION/APRIORI Block.
3-3) The AC solutions are aligned (using a 7-parameters) and compared to the
IGS00 stations at the current epoch.
ftp://igscb.jpl.nasa.gov/igscb/station/coord/IGS01P37_RS54.SNX.Z
3-4) The AC are compared to IGS00, to each other, to the previous week
solution and to the cumulative solution in order to identify and remove
outliers.
3-5) The weekly AC solutions are combined and added to the cumulative
combined solution. The cumulative combination is done to ensures 14
parameters singularity.
The weekly combined solution is aligned to the IGS00 of the current
epoch using a 7-parameters transformation. The singular cumulative
combined solution is aligned to the IGS00 of the reference epoch
using a 14-parameters transformation and the 54 ITRF station positions
and velocities. The IGS00 is a realization of ITRF2000.
For more details, see:
Blewitt, G., C. Boucher and J. Kouba, 1997, Procedure for ITRF continuous
realization, the report of the IGS GB, presented to the IGS Governing
Board Meeting held in San Francisco, Dec. 11.
Kouba, J., J. Ray and M.M. Watkins, IGS Reference Frame Realization, 1998

Centre, Darmstadt, Germany.
The combination software was developed at NRCan.
4) Remarks:
===========
ITR = IGS01P37_RS54.SNX
igs = igs03P1209.snx ( Weekly Combination )
IGS = IGS03P11.snx ( Cumulative Solution )
BuA = IERS Bulletin A
mit ncl are used to quality control the weekly combination.

4-1) Starting with GPS week 1143, the solutions are aligned to the
IGS01P37_RS54.SNX realization of ITRF2000.
4-2) Starting with GPS week 1078, UT1-UTC from IERS Bulletin A
is included in the erp files.
5) Results:
===========
5-1) AC (Variance Factor)^0.5 estimates:
==================================================
The residuals used in the estimation of the Variance Factor
are the differences between the cumulative combined solution
and each AC weekly solution.
SF = (Variance Factor)^0.5 = (Chi^2/dof)^0.5
Final(SF) = Apriori(SF) * Aposteriori(SF)
